Ed: ticking "Use Windows default audio device" should uncheck the other cards and stop
them being ticked again until the default is turned back off - in both the app and the
service. This replaces the old optional "shall I untick the others?" prompt with a hard
rule.
Behaviour (all follower lists: app received-outputs, outputs-to-send and inputs-to-send;
service outputs):
- Ticking the follower unticks every specific card in that list.
- While the follower is on, trying to tick a specific card is refused (the ItemCheck is
vetoed straight back to unticked) - you're either following the Windows default or
picking cards, never both.
- Unticking the follower frees the cards again.
- Enforced on load too, so a hand-edited/legacy profile carrying both comes up clean.
Shared, not duplicated: the veto + clear + follower-checked helpers live in
AudioDefaultFollower and are used by MainForm and the service dialog alike.
Removed the now-obsolete soft prompt and everything that hung off it:
- MainForm.MaybeUntickOthersForDefault + ResetDefaultAudioDevicePrompt.
- The "Reset the default audio device prompt" Options item (and its Alt+O,R).
- AppConfig.UntickOthersWhenUsingDefaultOutput/Input.
- Manual + About-box references to the prompt / reset item; the manual now documents
the exclusive rule and lists all three follower lists (the outputs-to-send follower
had been undocumented).
Test: "Default follower exclusivity" self-test - follower on clears + locks specific
cards, follower off frees them, unticking and the follower entry itself are never
vetoed. Gate 45/45.

Parallel code review of this session's changes surfaced several real bugs; fixed the
substantive ones (judgment/cleanup calls held for Ed):
- HIGH Clearing "remembered peers" was resurrected on the next launch: the per-profile
-> global migration re-ran every startup and re-unioned the profile file's stale copy.
Added a one-time AppConfig.RememberedPeersMigrated marker so migration runs once and a
cleared list stays cleared. Self-test pins the clear-then-reload scenario.
- MED PushModeWasapiBackend.Start rethrew on a device-open failure; nothing up the stack
wraps it, so device churn (a push-eligible single WASAPI source unplugged mid-open)
could crash the app. Now logs and stays stopped like MixingEngine/ASIO; the device
watcher / self-heal re-open when a device returns.
- MED Service self-heal: (a) the re-open "no send sources" path left PerformanceMode ON
and presence up while streaming nothing - now releases cleanly; (b) the 3-attempt
ladder never refunded, so 3 hiccups over a days-long stint meant permanent silence -
now refunds when real audio is heard, and resets on a device hot-plug.
- MED ApplyProfile resolved peers (DNS) and enumerated devices INSIDE the gate lock -
a boot-time DNS hang as SYSTEM stalled Suspend()/yield/self-heal. Moved outside the lock.
- LOW AudioSessionStartWatcher leaked the AudioSessionManager on every Rehook (the WASAPI
handle-leak fingerprint) - now disposed. New lifecycle self-test.
- LOW stale docstrings (send-all master toggle; ServiceUpdate in-place scheme; Profile
.SendAllApplications "neither reads nor writes").
Gate: 42/42 (added peers-migration + session-watcher-lifecycle tests).

Per-app capture (the "foobar alone = no sound" report):
- ProcessLoopbackCapture: take ActivateAudioInterfaceAsync's out operation as a raw
IntPtr (released after completion) instead of a typed interface. The eager RCW cast
of the not-yet-realised operation object threw InvalidCastException / E_NOINTERFACE
and killed EVERY specific-app capture at start.
- CompositeCaptureBackend: single IsPushEligible authority shared by Start,
UpdateSources and the coalesced rebuild. The update paths were missing the
ProcessLoopback exclusion, so switching whole-device -> one app kept the push
backend and fed it "proc:<pid>" (GetDevice ArgumentException).
- PushModeWasapiBackend: loud backstop rejecting process-loopback specs.
- Self-test: lifecycle test now FAILS on an activation error (it previously passed
green with the feature completely dead) + pure routing-rule checks.
Apps-mode UI (Ed 2026-07-16): the "Send all applications" checkbox is GONE from the
main window - applications mode always means picking specific apps; whole-system
audio is devices mode's job. Active list = running apps + any ticked app that is not
running ("(not running)" so it can be unticked); Remembered list = global address
book minus whatever is ticked. In-place list reconcile (no Clear+rebuild) kills the
NVDA double-read of the toggled row. Profile.SendAllApplications stays for the
SERVICE (deliberate divergence - a headless lock-screen sender wants system audio).
Remembered lists now genuinely machine-wide (AppConfig-backed): the settings store is
an intra-process cache, so remembered applications were forgotten on every exit and
remembered peers were per-profile in practice. Both books moved to AppConfig; legacy
per-profile peers are unioned in on profile load; profile save snapshots the global
book back for old-build compat. Cross-instance persistence pinned by self-test.
Service (issue #23): 15s capture pulse (callbacks/bytes/pre-encode peak/frames sent)
while sending - distinguishes "endpoint mix is genuinely silent at the lock screen"
from a pipeline fault, which callbacks alone cannot.
Gate: 38/38.

New global setting in Preferences -> General, right after "Browse for
profiles folder": a list "Auto-save non-read-only profiles" with Never /
Every 2 / 5 / 10 / 15 / 20 / 30 minutes. When enabled, RemSound periodically
saves the current profile, but ONLY if it is a real saved profile, is NOT
read-only, and has unsaved changes -- and it saves SILENTLY (no save cue,
no confirmation), so it never interrupts the user.
- AppConfig.AutoSaveNonReadOnlyMinutes (machine-wide, 0 = Never = default).
- SaveProfileTo gains a playCue flag; auto-save passes playCue: false.
- MainForm autoSaveTimer + ApplyAutoSaveTimer + ShouldAutoSave guard,
re-applied live when the setting changes in Preferences.
- New self-test "Auto-save non-read-only profiles": options list, AppConfig
persistence, the guard (read-only / blank / unchanged all skipped), and the
timer turning on/off. Gate 28/28.

Local checkpoint - NOT for public release. Ed: the service profile must never be
reachable except through the Service menu.
Also fixes a real bug: the service runs as SYSTEM, whose per-user data folder is NOT the
interactive user's - so a profile saved in the user's profiles folder (or AppConfig, both
per-user) was invisible to the service. It would have idled, never streaming.
- New RemSound.Core.ServiceStore: the service profile + its settings (logging) live in a
MACHINE-WIDE ProgramData\RemSound\service location - same absolute path for the user
(config dialog) and SYSTEM (service). Moved ServiceProfileName/ServiceLoggingEnabled off
AppConfig (per-user) onto this store.
- ServiceSendHost.FromConfig + RemSoundService now read ServiceStore; ConfigureServiceProfile
saves there (and migrates + deletes any profile left in the old user-folder location).
- Because it's no longer in the user's profiles folder, it can't appear in the startup
picker, File->Open, Recent profiles, or the password manager (all of which read the user
ProfileStore); the reserved-title filter in ListProfileTitles stays as belt-and-braces.
- Password button renamed "Set service profile password".
- New self-test "Service profile isolation": store is under ProgramData, the reserved title
is filtered from the listing, and it round-trips through the machine-wide store.
Gate 27/27.

Local checkpoint - NOT for public release. First increment of the send-only
Windows service feature (design in memory/project_remsound_service).
THE SPIKE PASSED: the send engine runs fully headless (no window, no message
pump) and streams, proven by a real self-test — the one genuine unknown that
gated the whole feature. Also proves the app-yield model end to end.
What's in this increment (all headless, all tested, 19/19 gate):
- AppConfig: ServiceProfileName + ServiceLoggingEnabled (machine-wide).
- InteractivePresence (Core): the cross-session app-yield token. App holds a
Global\ mutex for its lifetime; the service checks it and yields while an
interactive app is present, resuming when it closes OR crashes (OS frees the
mutex). Name-parameterised internal seams for isolated testing.
- ServiceSendHost (App): loads a send-only profile and streams it to its peers,
WASAPI-only, no ASIO/receive. ApplyProfile/Suspend/Resume + a RunLoop that
drives them from the presence token with a settle delay. v1 sends to direct
peer addresses (LAN/port-forwarded); NAT/relay discovery stays the app's job.
- Program.cs: the interactive app now acquires the presence token at startup so
a future service yields to it.
- Tests: "Service app-yield token" (held=present, released=absent) and "Service
send host (headless stream + yield)" — streams a captured device to a local
receiver over loopback, verifies start/suspend/resume, then drives the full
RunLoop against the token (held=suspended, released=resumes-and-flows).
Still to come (later increments): the --run-service entry + Windows-service
registration, the Service menu, the 3-tab config dialog, updater integration,
docs. None user-facing yet, so nothing deployed.

Local checkpoint - NOT for public release. Builds on the engine core commit.
Ed's revisions to the plan: the send-mode chooser lives on the Input/Output tab
(not Preferences), right after "Send my audio", and the setting saves per profile.
Input/Output tab:
- New "How to send WASAPI audio" listbox (Alt+6) after the send checkbox, with
two rows: send whole sound devices (classic) or send specific applications.
Switching it swaps the tab live between the loopback-outputs list and the app
section. Hidden entirely on Windows too old for process loopback (mode pinned
to devices), so nothing changes for Win7.
- Applications section: "Send all applications" master checkbox (Alt+7, ticked by
default = whole system audio, same as today) and an "Applications to send"
checked list (Alt+8) shown only when the master is unticked.
- All house controls (AccessibleCheckBox, MnemonicLabel, WireCheckedListAccessibility),
accessible names + Alt-shortcut suffixes, tab order slotted in.
Behaviour:
- App list reconciles on a 3s timer while visible: apps appear/disappear as they
open and close, ticks preserved by process NAME, and a ticked app that closes
stays in the list marked "(not running)" and resumes when it reappears.
- ApplySendSources: devices mode unchanged; applications mode sends either the
default-render loopback (send all) or one process-loopback spec per running
process of each ticked app. WASAPI mics and ASIO run alongside in both modes.
- Process-loopback sources are excluded from the single-source push-mode fast
path (it opens an MMDevice; a "proc:<pid>" id has none) - they go via MixingEngine.
- "Is anything being sent" status/tray gates account for applications mode.
Persistence moved from AppConfig to Profile: WasapiSendMode / SendAllApplications /
SelectedSendApplications. Profile round-trip self-test extended. Gate: 15/15.

Local checkpoint - NOT for public release.
Fan-out (every received stream to every selected output, no added latency):
- SessionPlayout mirror replicas fed the same decoded bytes; delicate ReadFloats untouched.
- PlayoutEngine reconciles replicas per active output lane; per-route tuner
aggregation keeps lanes from disturbing each other. Recording dispatch gated
to the recording route only.
- PeerDspChain.Clone() gives each output lane independent biquad state.
- ReceiverSelfChecks.FanOutToBothOutputs proves both lanes get audio (self-test).
Offline-marker pile-up fix:
- ResolvePeerDisplayName strips the " (offline)" marker before reuse, so a ghost
peer no longer compounds the suffix hundreds of times in the status line.
Issue #19 (Use-Windows-default follower in the loopback send list):
- DefaultLoopbackSendFollower resolves to the current default render device's
loopback spec, re-applied when the default changes.
Per-application send engine core (issue #20) - WASAPI-only, Win10 19041+ gated:
- CaptureKind.ProcessLoopback + ProcessLoopbackId ("proc:<pid>").
- AudioAppEnumerator: snapshots apps with audio sessions, tracked by process
name, releasing every session object each pass so nothing piles up.
- ProcessLoopbackCapture: IWaveIn over the process-loopback activation API
(hand-rolled COM interop; NAudio has no binding). Fixed 48k/float/stereo.
- CaptureSource IWaveIn overload; MixingEngine opens "proc:<pid>" sources with
no MMDevice and no render keepalive. ASIO path untouched.
- Self-test enumerated real apps on hardware; support gate verified.
UI (Preferences device/app mode + app checklist), ApplySendSources app specs,
and the reconcile timer are still to come. Gate: 15/15.

Adds an Appearance tab (after General) and moves the colour theme and "show volume/pan/EQ tab" into
it, per Ed. New on that tab:
* Main tab order — a list of the four main-window tabs (all shown, even when the pan/EQ tab is
hidden) with Move up / Move down buttons to reorder them. Saved to AppConfig.MainTabOrder and
applied by the new ApplyMainTabLayout (rebuilds the tab strip in order, dropping pan/EQ when off,
preserving selection). Replaces RefreshPanEqTabVisibility.
* Enable discovered / remembered peers lists on the Connectivity tab (AppConfig.ShowDiscoveredPeers
/ ShowRememberedPeers, both default on). RefreshConnectivityListVisibility hides the row's label
and its list wrapper when off. Row labels are now captured for this.
All apply when Preferences closes. Manual updated. Build clean; --selftest passes; deployed to both
test folders. Held for next release.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
* Connectivity tab order: Add peer by IP now sits right after Rename peer (before the Discovered
list), grouped with the connected-peer actions, per Ed's requested order. Dropped the second
section header (only the lock toggle was under it).
* Audio I/O labels: "Set volume for all received audio" → "Master volume for received audio" (the
code never got this rename, only the manual had). Device lists now say "audio": "...for received
audio" and "WASAPI/ASIO audio inputs/outputs to send". Labels + AccessibleNames updated together.
* Add EQ band dialog: the spin/edit boxes now select-all on focus, so a typed value REPLACES what's
there instead of being inserted next to it and reverting (typing 2.5 over 4.0 now works).
* Parametric bands list: Left/Right arrow nudge the selected band's gain by half a dB, live —
up/down still move between bands. NVDA re-reads the band's new dB.
* Recording settings: source list reordered to Both (top, now the default) / Received / Sent;
display order decoupled from the RecordingSource enum. Default RecordingSettings.Source = Both.
* Preferences: Colour theme is now first in the General tab order.
Manual updated. Build clean; --selftest passes; deployed to both test folders. Held for next release.

Turns the flat friendly-name map into a proper machine-wide book (AppConfig.NamedPeers), and adds a
management dialog. Held for next release.
* New NamedPeer record (machine name, friendly name, last address, last-seen UTC). AppConfig gains
NamedPeers; the legacy PeerFriendlyNames map is migrated into it once on load, then no longer
written. The book stays machine-wide and profile-independent (it always was — this just enriches it).
* Only deliberately-renamed peers are recorded (per Ed) so the list can't balloon. A named peer's
last address / last-seen are updated in memory each tick while connected; persisted on address
change and on app close (timestamp-only changes don't thrash the disk).
* Options → Manage named peers (Alt+O, N): lists each named peer as "friendly — machine — last seen
date, address"; Rename (Alt+R / F2 / double-click) reuses RenamePeerDialog; Delete (Alt+D / Del)
forgets the name. Edits refresh the connected/discovered lists, the volume/pan/EQ list and details
box live.
* ApplyFriendlyName now records machine name + last address alongside the name.
Manual updated (readme.html + MANUAL.md). Build clean; --selftest passes; deployed to both test folders.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
Add band dialog (from testing feedback):
* Tab order is now Start, End, Gain, OK, Cancel (OK was after Cancel).
* Gain box takes decimals like 1.5 (half-dB steps); parametric list shows one decimal.
* The two frequency boxes start empty — nothing prepopulated to mislead; both required on OK.
New Connectivity-tab feature (held for next release):
* Rename peer (Alt+M) opens a dialog to give a peer a friendly name, with a Clear custom name
button. Names are keyed by the peer's MACHINE NAME (stable across restarts, IP changes and
networks), stored machine-wide in AppConfig.PeerFriendlyNames, and resolved everywhere a peer
shows: both peer lists (via PeerListItem.DisplayNameProvider), the volume/pan/EQ list, the
status line and split-recording filenames. Manual-by-IP peers with no announced name fall back
to keying by address.
* Peer details (Alt+E): a read-only box for the highlighted connected peer showing name, machine
name, IP, connected-for, link health + ping, what they're sending, and whether they're
receiving our audio. "Sending: 2 devices on ASIO at 48 kHz, Opus" is derived from the live
receive streams — each stream is one device and its lane gives WASAPI vs ASIO — so NO protocol
change and no new privacy exposure. AudioReceiver.ActiveFormatsFromAddress added for this.
Manual updated (readme.html + MANUAL.md). Build clean; --selftest passes; deployed to both test
folders. Held for next release.

Reworks the per-peer shaping tab (held for next release):
* Renamed the tab to "Volume, pan and EQ for peers"; the Preferences toggle now defaults ON.
* Collapsed the two master switches (Enable EQ / Enable pan) into ONE: "Enable volume, pan and
EQ for all peers" (Alt+E). Volume now obeys it too. PeerDspChain.Build takes a single enabled
flag; Profile.EnableAllPeerShaping replaces the two bools (old ones kept for load-migration).
* Peer picker is now a CheckedListBox: ticking a peer shapes them (per-peer bypass via new
PeerShaping.Enabled, default true); the focused row is the one the controls edit. Effective
shaping = master switch AND that peer's tick. Letter-nav suppressed so keys never toggle a tick.
* Three EQ modes, renamed: "3 band simple EQ", "12 band advanced graphic EQ", and the new
"16 band parametric EQ" (PeerEqMode.Parametric16Band).
* Parametric EQ: up to 16 user bands, each a boost/cut across a start->end range (PeerShaping
.ParametricBands; ParametricToPeaking maps range -> peaking centre+Q, shared by DSP and curve).
Add band dialog (spin-or-type, numeric-only, live preview, OK/Escape); Bands list sorted
bass->treble reading "X Hz to Y Hz, plus/minus N dB"; Delete key / Delete button, multi-select.
Set peer EQ to default clears the parametric list too.
* dB now spoken as words ("plus 3 dB" / "minus 6 dB" / "flat") on the graphic sliders and the
parametric list, since NVDA users typically have punctuation off and never hear a "+".
* New unbound machine-wide global shortcut "Toggle volume, pan and EQ for all peers" (not stored
in any profile) via the hotkey controller + settings store.
* Renamed the Inputs/outputs "Set volume for all received audio" to "Master receive volume".
* Added EqCurveControl: a purely-visual EQ response graph (not focusable, invisible to NVDA).
* Full manual sweep (readme.html + regenerated MANUAL.md).
Build clean; --selftest passes. Deployed to both test folders. Held for next release.

New feature (Ed's jam-mixing request): pan and EQ each peer's signal independently.
Engine (zero added latency — per-sample, applied to each peer's isolated block just
before the mix): PeerDspChain (balance pan + RBJ biquad EQ) built on the UI thread and
swapped onto SessionPlayout via a volatile reference; PlayoutEngine remembers it per
address so a reconnecting peer keeps its shaping; AudioReceiver.SetPeerDsp facade.
Model: per-profile PeerShaping dict (keyed by peer address) + EnablePan/EnableEqForPeers
master switches; machine-wide AppConfig.ShowPanEqTab. Fixed band layouts in PeerEqBands
(3-band tone control: bass/mids/treble shelves+bell; 10-band ISO graphic EQ), +/-12 dB.
UI: a "Pan and EQ" tab (before Audio profile, shown only when ShowPanEqTab is on) with
the two enables, a connected-peer picker, a pan slider (balance, keeps stereo), a
"reset EQ" button (clears both modes' bands, leaves pan), a 3/10-band mode picker and its
band sliders — all TrackBars (arrow + page-up/down), updating in real time and saved per
profile. Sliders set a friendly AccessibleName on change (pan centre/left/right %, band
dB). "Show the Pan and EQ tab" checkbox added to Preferences > General.
Everything is off by default (tab hidden, both enables off), so this is dormant for all
users until switched on. Builds clean. Pending Ed's hands-on testing before release.

Andre confirmed (via NVDA speech history) that holding the speak-status hotkey
doesn't repeat or spam — so the defensive toggle that let users disable the
double-press-to-copy was needless configurability. Removed the Preferences
checkbox and the DoublePressStatusToCopy setting; double-press-to-copy (Andre's
own idea) stays, now simply always on. There was never any debounce/anti-spam
code to remove — the only timing is the 600 ms double-tap detection window, which
is the feature itself. Manual updated to drop the toggle line.
Held for the next release (the toggle never shipped).

Preferences General-tab checkbox "Double-press the speak-status hotkey to copy the status to the
clipboard" (Alt+C), machine-wide (AppConfig.DoublePressStatusToCopy), on by default. When off, a
double press just reads the status again. SpeakStatusLine reads the flag only when the timing already
qualifies, so a normal single press never touches the config. Manual's speak-status section now
covers the line-by-line read, GB totals, and the double-press copy + its toggle.
Held for the next release.

- New "Use Windows default audio device, follows Windows changes" entry at the top of the
received-output and send-input WASAPI lists. Resolves the current Windows default live,
re-routes automatically when the default device changes, works alongside specific devices,
and persists across launches (a follower can't go stale). Optional "untick the others?"
prompt with a remembered "don't ask again", reset via a new Options item "Reset the default
audio device prompt".
- Manual updated for the feature, plus a sweep that corrected the now-stale Options-menu
section (retired Startup-behaviour item, four->five Preferences tabs, missing entries).
About changelog and RELEASE_NOTES updated; version 4.6.

- Pre-v4.4 upgraders are offered a one-time dialog to copy their keyboard shortcuts
from one of their profiles (still readable in the profile files) instead of being
reset. Users who already went through v4.4's reset are deliberately NOT re-offered
(gated on KeyboardShortcutsGlobalNoticeShown). New KeyboardShortcutImportDialog +
AppConfig.KeyboardShortcutsImportOffered + MainFormHotkeyController.ReloadAndReRegisterAll.
- Keyboard shortcuts dialog: new "Clear this shortcut" button; Delete inside the
capture box leaves a shortcut unassigned.
- Relabelled the three RemSound-app remote rows to "Send remote RemSound volume/..."
to distinguish them from the Windows-global ones.
- Manual (readme.html + MANUAL.md), About changelog, RELEASE_NOTES updated; version 4.5.

Fixes issue #14: shortcuts were stored on each Profile, so one set on profile A
didn't apply on profile B and seemed to vanish on switch. They now live in
AppConfig (one set shared by every profile). RemSoundSettingsStore's Load*/Save*
hotkey methods re-point to AppConfig (callers unchanged); the per-profile cache
fields, profile load/save plumbing, and the HotkeySetting helper class are removed.
Profile's HotkeyRecord fields stay only for back-compat deserialization.
On upgrade, shortcuts reset to defaults (there's no single correct set to carry over
since profiles could hold different/partial sets). A one-time startup notice tells
upgraders to re-set them; fresh installs are silently marked done (nothing to reset).
Manual, About changelog and RELEASE_NOTES updated; csproj <Version> 4.4.

- New screen-reader hotkey "Speak the RemSound status information" (issue #13):
reads the status line aloud through the active screen reader via Tolk, fires from
anywhere (system-wide), unset by default. Built behind an IScreenReaderOutput seam
so a future build can swap Tolk for Prism on Windows 10+ without touching callers.
Tolk DLLs vendored under tolk/ and shipped next to the exe.
- New Logging tab in Preferences: Enable logs + Write logs now moved there, plus
opt-in startup "warn if logs folder exceeds N MB" and "delete logs older than N days",
and a "Delete all logs" button (Yes/No confirm). New LogMaintenance helper + AppConfig
settings drive it.
- Manual (readme.html + regenerated MANUAL.md), About changelog and RELEASE_NOTES
updated in plain English; csproj <Version> bumped to 4.3.

Audio cues
- Cues for send/receive on-off, minimise/restore, checkbox tick/untick, and tab switch
- Soft keyboard clicks while typing, with a distinct passkey sound on password fields
- Per-cue "Choose sound" variant picker; "(none)" silences a cue; front-most missing-sound warning
- Send/receive cues take priority over the generic checkbox sound; programmatic ticks stay silent
Preferences
- Redesigned into four tabs (General, Audio cues, Startup behaviour, Update settings)
- Startup behaviour moved in from the Options menu
- NVDA now announces the dialog on open (focus a real named control, not the quiet tab control)
Auto-tune
- Cause-aware: tells device render-callback stalls (more buffer can't fix) apart from genuine
network/buffer starvation, so it no longer pins latency high on chunky onboard cards
- Lowering the target eases the buffer down (glide) instead of trimming it, so no clicks while tuning
Sounds layout
- Shipped defaults moved out of the per-user folder into an install-side "default sounds" folder,
so updates can refresh them; user customs are Browse-picked file paths and are left untouched
- Startup migration removes both legacy sound folders; verified from oldest (v1.0-v3.3) and v3.4 layouts
Quiet automated launches
- New --silent launch flag mutes all cue sounds and suppresses the startup dialogs (migration notice,
update check, Realtek/mic/missing-sound warnings) so test launches never disturb the user
- run-tests / build-release / SelfTest repointed to the new "default sounds" layout

Part 1 - "Uncheck all inputs and outputs" button now also resets the ASIO driver to "(none)":
renamed to say so, and UncheckAllDevices sets asioDriverBox to row 0 for a full clean
WASAPI-only, nothing-selected state.
Part 2 - checkbox tick/untick sounds: every checkbox toggle anywhere in RemSound now plays a
short cue (check.wav on tick, uncheck.wav on untick) - instant feedback on which way a box
went, especially in the inputs/outputs lists. New CheckSoundService + two machine-wide cues
(CheckboxOn/Off) with the usual numbered-variant + Preferences treatment. Hooked from
AccessibleCheckBox.OnCheckedChanged and the device lists' WireCheckedListAccessibility, both
gated on the control being Focused so a genuine user toggle clicks but bulk programmatic
(un)checking (profile load, "uncheck all") stays silent. Reloaded at startup and on cue change.
Tests + manual updated; .sfk byproducts cleared.
Remaining for the overhaul (next): tabbed Preferences (General / Audio cues / Startup behaviour /
Update settings), the cue-list redesign with a "none" option replacing per-cue checkboxes, moving
Startup behaviour out of the Options menu, and a front-most "missing sound file" error.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
Six new machine-wide cues, each with the same numbered-variant + Preferences treatment as
the others (enable tickbox, Choose default sound picker, Play/Browse):
- Send turned on / off, Receive turned on / off: fire from OnStreamingCheckboxChanged, so
they sound whether the user clicked the in-window tickbox or pressed the mute shortcut
(the hotkey flips .Checked, which routes through the same handler). Suppressed during
profile load by the existing password-gate guard, so loading a profile doesn't blast them.
- Minimise (hide) / Restore (show): fire from the tray controller's Minimize()/Restore() on a
genuine visibility transition (guarded against no-op / startup-minimise).
Enable flags + custom-WAV overrides for these six live machine-wide in AppConfig
(EnableSendOnCue.., MachineCueCustomPaths) - they're app-level feedback, not per-profile
audio - so no Profile/settings-cache plumbing. TryLoadCueSound now also honours the
machine-wide custom path. PreferencesDialog gains a MachineRow helper + the six rows.
Sounds: shipped via the existing sounds\*.wav wildcard. Fixed an obvious typo in the
supplied files ("rcieve off 1.wav" -> "recieve off 1.wav") so receive-off has both variants.
Renamed the old single-name cue WAVs to Ed's numbered-variant set; added key/passkey and the
new cue sounds.
build-release.ps1: new step deletes the SoundForge .sfk peak-file byproducts from sounds\
before packaging (they never shipped - build is *.wav only - this just keeps the tree tidy).
Tests + manual updated for the six new cues.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
Cue sounds now ship as numbered variants ("connect 1.wav", "connect 2.wav", ...); the
count is never hard-coded so more can be added with no code change.
- CueSounds.cs: discovers a cue's "<base> <n>.wav" variants (case-insensitive) and
resolves the active default: per-profile custom WAV > machine-wide chosen variant >
first variant > silent. Wired into MainForm.TryLoadCueSound, the startup cue in
Program.cs, and PreferencesDialog.ResolveCueFilePath.
- AppConfig: DefaultCueSounds (machine-wide cueId -> chosen filename) and
EnableKeyboardClicks (on by default).
- Preferences: a "Choose default sound" listbox under the cue checklist - it lists the
selected cue's variants, arrowing it previews each sound and makes it that cue's
default. Plus a "Play keyboard clicks when typing into any edit field" checkbox.
- KeyClickService.cs: an app-wide WM_CHAR message filter + a low-latency NAudio mixer.
Typing into any edit field plays a random key click (key 1..N.wav); password fields
also play passkey.wav at the same instant. On/off live from the Preferences toggle.
Inert if the sounds are missing or the device won't open; never consumes the keystroke.
- csproj: ship every sounds\*.wav via a wildcard (variants, key clicks, passkey, future
additions) instead of stale per-file canonical names.
- Tests: resource checks (self-test + run-tests.ps1) now verify each cue has >=1 variant
and that key 1.wav / passkey.wav are present. Accessibility audit still green with the
new Preferences controls (Alt+D, Alt+K - no mnemonic clashes).
- Manual: variant picker, keyboard clicks, and the new sound-file naming documented.

Adopted from Andre's RemSound-smoke-test-agent-brief.md - the gaps our pack didn't
already cover:
- --config-dir <folder>: redirect ALL user state (config, profiles, logs, cue
sounds) to an explicit folder for this process only, applied at the very start of
Program.Main before the layout migration runs. Lets a test exercise a real build
without touching the user's live settings (the brief's safety rule 1). Works with
every command. AppConfig gains SetUserDataDirectoryOverride / an override on
UserDataDirectory; CommandLine.TryGetConfigDir parses it early.
- --smoke-test / --smoketest: alias for --selftest, matching the brief's vocabulary.
- run-tests.ps1: a cold-start + clean-close smoke (brief baseline steps 3-4) -
launches the GUI minimized against an isolated --config-dir, confirms it stays up,
that it used the isolated folder (real settings untouched), and that --close shuts
it down with no orphan process. SKIPs cleanly if a RemSound instance is already
running (machine-wide single-instance lock).
Manual + --help updated for both switches.

Receiver: a Mixed (plain) session is rendered on an active lane in BothIndependent mode instead of being skipped, so a WASAPI-only sender is no longer silent to a receiver that has an ASIO driver selected. Also port the per-session buffer depth-drain (stops the receive jitter buffer bloating).
Sender: add sndAudFr meter (audio frames actually sent) to localise capture vs send.
App: startup sound cue (machine-wide, Preferences); stop sending audio when no peer is reachable (issue #8). Version 3.9.1.
Server (relay): fix updater version-compare for multi-dot tags, guard the main loop against crashes, reject spoofed BYE from a mismatched endpoint.

- Recover an unplugged/replugged output sound card automatically (issue #5):
detect the dead WASAPI device and remember the receive-output selection so it
re-ticks and re-opens when the card returns.
- Adaptive per-card WASAPI buffer target sized to each card's pull chunk, held
stable so it never flits about under CPU/network load.
- Consolidate all per-user data (config, profiles, logs, sounds) into one
"user settings and logs" folder; migrate every older layout; exclude it from
the updater so custom cue sounds now survive updates.
- Mic-privacy detector: warn once when a Windows-blocked mic is switched on, or a
profile loads with one already on.
- All warning/notice dialogs now come to the foreground even when minimised.
- Apply volume + mute on profile load (were saved but not restored).
- Crash-safe (atomic) profile/config saves.
- Fix two resource leaks (push-mode capture MMDevice; UPnP DeviceFound handler).
- Remove dead code (baseline-diff machinery, dead ASIO probes, no-op stubs).
- Docs: readme.html, MANUAL.md, About-box changelog and release notes for v3.5.

Freezes the v3.4 feature set (everything since the v3.3 public release):
- Fix the receiver handle leak: the 3-second device-refresh timer reopened the
configured ASIO driver every tick, and Realtek's ASIO driver leaks Event+Mutant
handles on every open. Cache the ASIO probe per driver so it is opened once.
- Realtek ASIO block: detect a Realtek ASIO driver, offer once to disable it, and
never touch it again if disabled; Options-menu toggle to reverse. Global config.
- Device hot-plug is event-driven (AudioDeviceChangeNotifier) instead of a 3s poll;
debounced refresh, falls back to polling if registration fails.
- Quick profile switch: new global hotkey opens an NVDA-friendly popup of all
profiles (current marked); Enter/click switches; plays a new "profile menu open"
cue with Preferences mute + custom-sound.
- Announce assigned global hotkeys on the controls/menu items they drive (NVDA reads
"press X anywhere"). File > Open already had Ctrl+O.
- Held-back changes folded in: config-folder migration, codec-column fix, Tailscale
endpoint network-prune, empty-password guard, and the handle-leak diagnostics
(ProcessSelfMeter, HandleTypeProbe).
Version bumped to 3.4.0.

Headline: all audio is now encrypted (AES-256-GCM), keyed by a per-profile
password. Mandatory — v3.3 only interoperates with v3.3+.
Encryption
- RemSoundCrypto (Core): PBKDF2 key derivation, AES-GCM encrypt/decrypt
(low-alloc, into-span), password fingerprint, light on-disk obfuscation.
- Wire: SenderLane encrypts the audio payload (PCM split across parts when the
+28 overhead crosses MTU); AudioReceiver/StreamSession decrypt via a shared
single-thread AudioDecryptor. Fingerprint piggybacks on the Format packet
(offset 36, backward-compatible) so a peer can detect a password mismatch.
- Profile.Password (scrambled), carried through BuildCurrentProfile; MainForm
derives + pushes the key/fingerprint to sender + receiver (RecomputeAudioCrypto).
- UX: ask-for-password on profile create; File -> Change this profile's password
(ProfilePasswordDialog); Options -> Profile passwords (manager); a gate that
prompts before streaming without a password; and a clear "passwords don't
match" / "peer needs to update" message driven by the fingerprint.
Cue fixes
- CuePlayer (NAudio) replaces System.Media.SoundPlayer, which silently failed
on the 96 kHz/24-bit cue WAVs (and any custom file) — cues now play reliably,
resampled to 48 kHz/16-bit. Also fixes the Preferences preview button.
- Connect/disconnect cues now audio-gated with hysteresis: connected when audio
flows OR heartbeat healthy; lost only when audio stops AND heartbeat
unreachable. Kills false disconnects and the receive-only "no cues" case.
- Honest cue logging (played / muted / not loaded).
Smaller
- Endpoint stickiness: keep the audio target pinned to the heartbeat-proven
address instead of chasing a multi-homed peer's other (unreachable) address.
- "Online/offline" label now audio+heartbeat aware, not discovery-only.
- "Show what's new after each update" preference (on by default).
Docs: About v3.3 block, RELEASE_NOTES, README (encryption as a headline),
manual section 12 "Passwords and encryption" (+ renumber), MANUAL.md regenerated.
Version 3.2.0 -> 3.3.0.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
* New "Opus, live latency" codec mode: 2.5 ms frames (120 samples/ch at 48 kHz)
via the float-input encode path. End-to-end codec delay drops to ~5 ms (vs
~12.5 ms at standard 10 ms Opus). Test on LAN: 400 pps/lane, zero missed /
reordered / duplicate packets, ~15 ms one-way saved end-to-end.
* Wire-format change: AudioFormatInfo.FrameDurationMilliseconds renamed to
FrameSamplesPerChannel (int sample-count at announced sample rate). Removes
the lossy 48000*ms/1000 conversion that couldn't represent 2.5 ms. v3 <-> v3
exact; v3 <-> v2 still passes audio (Opus decoder is self-describing from
packet TOC) but v2 side over-sizes its buffer wildly. v2.x profiles auto-
migrate via <120 sentinel rule in RemSoundSettingsStore (anything below 120
is treated as legacy ms and multiplied by 48). Profile JSON key kept as
OpusFrameMilliseconds via [JsonPropertyName] so old profile files still load.
* Codec dropdown rebuilt with use-case names: "PCM 48K 24 bit - uncompressed",
"Opus, broadcast quality - loss tolerant", "Opus, live latency - for jamming
and monitoring". Middle 10 ms option retired; saved 480-sample profiles
collapse to broadcast quality (safer-side default).
* Profile auto-resume after self-update: RemSoundUpdater writes a one-shot
_resume-after-update.txt sentinel containing the active profile title before
exit; Program.Main reads + deletes it on next start and silently loads that
profile, skipping the picker. Helper batch's robocopy /XF excludes the
sentinel and the failure-branch cleans it up if the install aborts. Falls
through to normal startup behaviour (StartWithProfileTitle or picker) if the
sentinel is missing, empty, or names a profile that no longer exists.
* Read-only profile saves now go through on explicit Ctrl+S / File -> Save
with a one-time TaskDialog warning ("Save anyway" / "Cancel" + Do-not-show-
again). Lock continues to suppress the automatic unsaved-changes prompt on
close / profile switch (its main job). AppConfig.SaveOnReadOnlyMessageSuppressed
renamed to SaveOnReadOnlyWarningSuppressed; v2.x suppression flag is silently
discarded since the behaviour changed and the user needs to see the warning
once on each machine.
* Manual (readme.html) updated: codec table rewritten with the three new
choices and corrected bandwidth figures, send-rate description updated, new
sections "The same profile picks up automatically after an update" and
"Saving on purpose while a profile is locked".
* Subsumes the never-separately-released v2.2 work: native Opus encoder
(~97% less per-second memory churn on Opus send path via Concentus.Native),
efficiency tidy-ups (item 4 ASIO probe rate, item 6 WaitHandle, item 7
snapshot cache, items 14/16 heartbeat + discovery), legacy cleanup
(items 30/34/35/36: KeepAlive infrastructure, drift drop/repeat/accumulator
fields, fan-out cache stat). New diagnostic columns cpu/memMB/wsMB/
allocKBps/captureMs/sendMs/recvMs/renderMs gated on Enable-logs.
About dialog updated with v3.0 block at top; v2.2 block retained for the
subsumed work.

Headline features:
* Automatic router port opening (UPnP / NAT-PMP / PCP). Opt-in via
Preferences; surfaces external address + carrier-grade NAT detection.
* Lock profile (read-only). New File-menu tick that makes a profile
load-only — session changes don't persist, no save prompt on close.
Unblocks unattended shutdowns (NVDA gone, remote dropped, hibernate)
where the existing save prompt could deadlock.
* Check for updates on startup (default on) + brief countdown notice
before silent updates install, so a launch-time update doesn't make
the app silently vanish.
* "Cue sounds" -> "Audio cue sounds" label clarification.
Bug fixes:
* No sound after the computer wakes from sleep. PowerResumeHandler
rebuilds the audio backend automatically on resume; brief
"Reconnecting to audio driver" splash during the rebuild.
* Receiver audio silent after waking from hibernate. RefreshAudioDeviceLists
now treats a transient ASIO probe failure (returns -1/-1 because the
driver is mid-teardown / mid-reinit) as "retry next tick" instead of
clearing the user's tick selection.
Diagnostic-only changes (gated on the existing Enable-logs checkbox,
zero cost when off):
* AudioStepProbe split into cross-buffer vs within-buffer maxes so log
inspection can tell a real-content sharp transient apart from a
pipeline-boundary glitch. Plumbed through every probe owner.
* New rxNetGapMs + gc0/gc1/gc2 delta columns in the diag log to split
receive-side jitter into network-layer vs managed-runtime causes.
Files touched: RELEASE_NOTES.md + readme.html + 24 source files across
RemSound.Core / RemSound.Sender / RemSound.Receiver / RemSound.App.
Three new app files: PowerResumeHandler, RouterPortMapper,
UpdateInstallNoticeDialog.
Wire format and audio pipeline unchanged from v1.5 onward — v1.5
through v2.1 peers interoperate.
Bug fixes:
* BothIndependent recording was double-tapped — when both WASAPI and
ASIO outputs were ticked, recordings came out garbled and ~2x the
expected duration. AudioRecorder now uses four per-lane rings
(sent-wasapi, sent-asio, recv-wasapi, recv-asio) plus a writer-
thread mix step that drains min(wasapi, asio) frames and sum-mixes
with the soft-tanh limiter. Tap signatures gained a RenderRoute
parameter; Mixed maps to the wasapi slot.
* A peer announcing on the WASAPI lane was inaudible when the
receiver only had an ASIO output ticked (and vice versa). The
session opened, samples flowed into the SessionPlayout ring, but
ReadForRoute(AsioLane) skipped any session whose Route was
WasapiLane so nothing drained the ring. PlayoutEngine now tracks
per-lane "is this lane backed by a device" via volatile bools
settable through SetLaneActive(RenderRoute, bool), called from
CompositeRenderBackend.SetOutputDevices whenever the device split
changes. ReadForRoute admits orphan sessions when the other lane
is inactive.
Menu reorganisation:
* New Options menu (Alt+O) holds Recording settings (Alt+S), Keyboard
shortcuts (Alt+K, Ctrl+K), Startup behaviour (Alt+T), Preferences
(Alt+P, Ctrl+P). Pre-v1.5 these were scattered across File menu,
Record menu, and inside the Preferences dialog itself.
* Record menu mnemonic moved from Alt+O to Alt+K, rendered as
"Record (Alt+K)" so the chord is visible despite K not being a
letter in "Record". Alt+R is taken by Receive audio.
* File menu — new Recent profiles submenu (Alt+F, R) listing the
five most-recently-opened profiles. Press 1..5 inside the submenu
to jump to a slot. Missing files are skipped from the menu but
kept in storage.
* Rename current profile moves to Alt+M (was R), Minimise to tray
moves to Alt+N (was M).
* Lock to audio clock was Alt+K, now Alt+D.
UX additions:
* Ctrl+O = Open profile (matches the menu chord).
* New global hotkey: Start / Stop recording. Pickable from Options
-> Keyboard shortcuts. Unbound by default. Works system-wide.
Wire format and audio pipeline unchanged from v1.4 — v1.4 and v1.5
peers interoperate.
