EdnunpandClaude Opus 4.8 fd5c31740a Release v4.3: speak status line (Tolk) + Logging tab with housekeeping 
- 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.

EdnunpandClaude Opus 4.8 dd70613017 v3.4: handle-leak fix, Realtek ASIO block, device notifications, quick profile switch, hotkey announcements 
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.

EdnunpandClaude Opus 4.8 959720f54d Release v3.3: end-to-end encrypted audio, plus cue and reliability fixes 
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.

EdnunpandClaude Opus 4.8 cdcac859c4 Release v3.2: update sound cue + single-instance bring-to-front fix 
- New "Update sound" cue (CueId.Update / update.wav). Plays just before an
  update starts installing, on every path (manual, background-silent,
  startup-silent), so a silent background update gives an audible heads-up
  before RemSound closes to restart. Per-profile mute + custom-sound override
  in Preferences, same infrastructure as the other cues:
    * Profile.EnableUpdateCue + RemSoundSettingsStore Load/Save + round-trip
    * MainForm updateSound field, TryLoadCueSound, play in InstallUpdateAsync
      gated by LoadEnableUpdateCue
    * PreferencesDialog "Update sound" CueRow + ResolveCueFilePath mapping
    * update.wav shipped in sounds\ via csproj Content
- Single-instance "switch to the running copy" now actually brings the window
  to the front. The second copy grants the running copy foreground rights via
  AllowSetForegroundWindow before signalling, and lingers briefly so it can
  raise itself before we exit — without this, Windows' foreground lock left
  the running window only flashing in the taskbar (Ed's report).
- Docs: About box v3.2 block, RELEASE_NOTES.md, manual cue section (now seven
  cues, with the update cue described), MANUAL.md regenerated.
- Version bumped 3.1.3 -> 3.2.0.

EdnunpandClaude Opus 4.7 70c2669d70 Bump to v3.1.0: new audio cues (save, profile-switch), per-profile custom cue paths, redesigned tray menu 
Two new cues join the existing connect / disconnect / record-start /
record-stop set:
  * profile-save cue (sounds\save.wav by default) fires in
    SaveProfileTo after a successful Save or Save As. Honours the
    Profile.EnableSaveCue per-profile flag.
  * profile-switch cue (sounds\profile.wav by default) fires in the
    MainForm Shown handler after a profile finishes loading - covers
    both startup-with-profile and mid-session profile switches.
    Honours the Profile.EnableProfileSwitchCue flag. Because cue
    loading runs AFTER settings.ApplyProfile in the ctor (line 542),
    the profile being entered determines which sound plays - not the
    one being left, exactly as Ed asked.

The audio cue UI in PreferencesDialog stays as a CheckedListBox (up /
down navigates, Space toggles) with TWO action buttons below that
operate on whichever cue is selected:
  * Play [cue name] (Alt+P) - previews via SoundPlayer.Play on the
    resolved path (custom override if set, default in sounds\
    otherwise). Independent of the tick state.
  * Browse for [cue name]... (Alt+B) - opens a WAV picker. If the
    user picks a file inside RemSound's own sounds\ folder, it's
    treated as "use default" and the override is cleared - avoids
    pinning the user to a specific shipped default that a future
    release might replace. Right-click "Use default sound" reverts.

Custom cue paths AND enable flags are per-profile. Lives on
Profile.CustomCuePaths (Dictionary<string,string>) and the per-cue
EnableXxxCue bool? properties. Cache mirror in
RemSoundSettingsStore.Settings.

All default WAVs moved from the install-root flat layout into a
sounds\ subfolder (csproj Content rules updated). save.wav and
profile.wav are bundled defaults.

Tray menu rewritten (MainFormTrayController) per Ed's spec:
  * Show RemSound (W) - now uses Win32 SetForegroundWindow after the
    standard Activate() because WinForms Activate is blocked by the
    foreground-lock when invoked from a tray-menu click, which left
    screen-reader users having to Alt+Tab to reach the restored
    window.
  * Enable sending (S) / Enable receiving (R) - tickable, reflect
    current state, TOGGLE rather than always-on.
  * Profiles (P) - submenu populated from AppConfig.RecentProfiles
    with the same &1..&5 mnemonics the File menu uses. Pre-populated
    once at construction so WinForms recognises it as a submenu and
    fires DropDownOpening - originally I relied entirely on the
    open event, which the framework skipped for items with no
    DropDownItems, producing the "Profiles does nothing" bug.
  * Exit (X).

Tray tooltip now built dynamically from snapshot tick (1 Hz):
"RemSound - [recording for MM:SS,] N peer(s), sending (lane),
receiving (lane)". Recording timer only included while
RecordingController.IsRecording is true (added
RecordingStartedUtc accessor for the elapsed calculation). Lane is
derived from which device-list ticks are active, not just the audio-
mode setting, so a BothIndependent user with only WASAPI inputs ticked
honestly reads as "sending (WASAPI)".

Fixes:
  * Initial tooltip "RemSound" produced a "RemSound RemSound" read on
    NVDA because the process name and tooltip matched. Set to
    "RemSound - starting up" so the duplicate disappears.
  * Recent profile menu items no longer carry a "Recent profile N:"
    AccessibleName prefix in either the tray submenu or the File
    menu's Recent profiles - now just the profile name. Number-key
    mnemonics (&1..&5) untouched.

Manual (readme.html) updated: new section 17 "Audio cue sounds"
documents all six cues, the Play/Browse buttons, the right-click
"Use default sound", and the per-profile semantics. Sections 17-21
renumbered to 18-22. New "System tray icon and its menu" subsection
inside section 4 documents the redesigned right-click menu and the
hover tooltip. MANUAL.md regenerated via sync-manual.py. About box
gets a v3.1 block at the top. RELEASE_NOTES.md fully rewritten for
v3.1.

No wire format change - v3.1 talks to other v3.0.x machines exactly
as before.

EdnunpandClaude Opus 4.7 af0e7c3fff Bump to v3.0.0: Opus live latency, codec rename, profile-resume after update, save-through-lock 
* 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.

Ednunp 79b28b6c02 Bump to v2.1.0: UPnP, read-only profile lock, sleep/hibernate audio fix 
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.

EdnunpandClaude Opus 4.7 4915a9afe1 Bump to v1.5.0: cross-lane routing fix, recording double-tap fix, menu reorg 
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.

EdnunpandClaude Opus 4.7 c59e413c1f Bump to v1.2.0: recording, sound cues, drift compensation, diagnostics 
New user-facing features:

* Recording. Dedicated Record menu (Alt+O — moved from Alt+R to
  avoid clashing with the Receive audio checkbox), Start/Stop on
  Ctrl+R, settings dialog, per-profile source / format / bit-depth /
  channel-mode / folder. Three source modes (received only, sent
  only, both). Files are crash-resilient — a process crash
  mid-recording leaves a playable file containing everything up to
  the last header refresh (~5 seconds).

* Four output formats, all functional:
    - WAV: 16/24-bit PCM or 32-bit float, custom writer with
      periodic RIFF re-patching.
    - MP3: LAME 128–320 kbps CBR (via NAudio.Lame).
    - OGG-Opus: 96–256 kbps VBR (via Concentus.Oggfile, reusing the
      Concentus encoder from the wire path).
    - FLAC: 16/24-bit lossless (via CUETools.Codecs.FLAKE — pure
      managed, no native DLL).

* Recording start/stop sound cues. record start.wav and
  record stop.wav play around the recording transition. Played via
  System.Media.SoundPlayer to the default Windows output, separate
  from the recording pipeline so a normal recording does not contain
  the cue.

* Per-cue Preferences. The old single "Mute connect/disconnect
  sounds" checkbox is replaced by a CheckedListBox: Connect /
  Disconnect / Recording start / Recording stop. Old profiles with
  the legacy MuteConnectionCues=true are honoured on first load via
  a migration path in the new Load* helpers.

* Receiver-side drift compensation switched from discrete
  single-frame splices to a continuous WdlResampler at a smoothed
  rate ratio. SessionPlayout.cs rewrite.

Diagnostics (only active with Enable logs ticked):

* Per-stage discontinuity probes — sender raw capture (per backend,
  PushModeWasapi + Asio both wired), sender pre-encode (now per
  lane in BothIndependent, fixing a cross-stream artefact), receiver
  post-decode, post-ring, post-resampler.

* Wire-level packet sequence tracking on each PCM stream — in-order
  / missed / reordered / duplicated counts in the diag log.

* Clipped-sample delta in the diag log.

* New AudioStepProbe in RemSound.Core with per-channel scan helper.

UI changes:

* Record menu uses Alt+O (Rec&ord). Inside the menu, item mnemonics
  unchanged (S / T / O / C).

* Auto-tune interval combo label is mode-aware: "Auto-tune latency
  interval" in classic modes, "Auto-tune interval — WASAPI and ASIO"
  in BothIndependent. The combo's Enabled state now follows EITHER
  lane's auto-tune checkbox (was only the WASAPI one — bug).

Wire format and audio pipeline unchanged from v1.1 — v1.1 and v1.2
peers interoperate.

EdnunpandClaude Opus 4.7 768875cebb Add priority mode + always-on network packet priority 
Priority mode (per-profile toggle, Audio profile tab, Alt+U):
- Bundled PROCESS_POWER_THROTTLING_STATE with EXECUTION_SPEED and
  IGNORE_TIMER_RESOLUTION flags (keeps CPU at full clock + 1 ms quantum
  pinned regardless of OS idle decisions)
- PowerSetRequest(EXECUTION_REQUIRED) + SetThreadExecutionState so the
  system can't decide we're idle and downclock
- timeBeginPeriod(1) for 1 ms scheduler quantum
- ProcessPriorityClass.High, ProcessMemoryPriority normal, working-set
  minimum locked via SetProcessWorkingSetSizeEx(HARDWS_MIN_ENABLE)
- Fully reversed on toggle-off and on form close
- Off by default (battery cost on laptops); explicit opt-in per profile

MMCSS thread priority on hot threads bumped from High to Critical
(network listener, mix loop, render thread) — always on.

Network packet priority (always on, no toggle):
- qWAVE flow on the outbound UDP socket at QOS_TRAFFIC_TYPE_VOICE with
  QOS_NON_ADAPTIVE_FLOW (Voice priority, DSCP 46/EF, WMM Voice on Wi-Fi)
- Silent fallback if qwave.dll missing or QoS service disabled
- Sender + receiver kernel UDP buffers bumped to 1 MB each (was
  256 KB send / 512 KB receive) for resilience against ~30 ms stalls

Bug fix: PreferencesDialog logging toggle no longer flags the profile
as dirty. Logging is a machine-local AppConfig setting; the spurious
ChangedAnyProfileSetting flag was triggering the unsaved-changes prompt
on exit after toggling logs alone.

Manual updated: new "Use CPU and Windows performance settings in high
priority mode (Alt+U)" subsection on the Audio profile tab, new
"Network packet priority (qWAVE / Voice / WMM)" subsection in the
network chapter, Alt+U row added to keyboard-shortcuts table.
