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. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> |

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.

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.

Bump to v3.1.3: single-instance lock + update/read-only reliability fixes
Fixes the chained-fault runaway Andre hit after an update (multiple copies
stacking, audio climbing to deafening, terminal kill to recover).
- Single-instance lock (SingleInstanceCoordinator + SingleInstanceDialog,
wired in Program.Main). A named mutex makes two copies impossible. A second
launch offers: switch to the running copy (default; surfaces it from the
tray via a named activation event), or force the running copy closed and
start fresh (Process.Kill, retried elevated if the target is elevated).
This is the structural fix that makes the stacking runaway impossible.
- Prompt-free update exit. InstallUpdateAsync sets updatingInProgress before
Application.Exit(); the close path's skipPrompt now honours it, so no
unsaved-changes dialog (whose default button is Cancel) can abort the
update's restart.
- Read-only persistence fix. BuildCurrentProfile now carries
currentProfileReadOnly into the saved snapshot. Previously a deliberate
save of a locked profile wrote ReadOnly=false, silently unlocking it on
disk — which re-armed the save prompt that then blocked the update.
- In-process double-install guard. updateInstallStarted stops the ~4 s
startup check and the background poll both staging an install + helper.
- Docs: About box, RELEASE_NOTES.md, readme.html + MANUAL.md ("Only one copy
of RemSound runs at a time").

Bump to v3.1.2: tray icon re-stamps on state change, recording shows as a flag
- Tray icon now re-registers itself (hide+re-show) whenever the meaningful
state changes — peer connect/drop, send/receive toggle, recording
start/stop — so the name a screen reader announces stays in step with
the live state. Fixes the persistent "no peers" then "1 peer" double
announcement that the old "show window then minimise again" trick used
to clear by hand. Same root cause as the v3.1.1 stuck-tooltip fix, just
exposed when the state changes a moment after the icon appears.
- Recording shows as a plain "recording" flag in the tray rather than a
live timer. A ticking timer would have either flickered the icon once a
second or left a screen reader announcing a stale time next to the live
one. Removed the now-dead FormatRecordingElapsed helper.
- Bundles the earlier Win7 updater fix (

Updater: distinguish 'no newer version' from 'check failed' on all three paths
Tech Singer's Windows 7 log from 2026-05-28 had this pattern: updater: GET https://api.github.com/repos/... updater: check failed: HttpRequestException: The SSL connection could not be established ... updater: startup check — up to date (v3.0.1) i.e. the SSL handshake to GitHub failed (Win7's TLS stack missing KB3140245 / KB4474419) but the updater logged 'up to date' and the user-facing message in CheckForUpdatesManually said the same. So a user with a broken update check has no way to distinguish that from genuinely having the latest version. Fix: * CheckForUpdateAsync now returns a discriminated UpdateCheckResult (UpdateAvailable / UpToDate / UpdateCheckFailed) instead of the old UpdateInfo?. Each return-null site is replaced with the appropriate concrete type. * The catch-all 'try { ... } catch (Exception ex) { return null; }' becomes 'return new UpdateCheckFailed(ClassifyFailure(ex), ...)'. ClassifyFailure walks the exception chain and maps to a coarse FailureKind enum: SecureConnection (TLS/auth), Timeout, HttpError, NetworkUnreachable. SecureConnection is broken out separately so the manual-check UI can point Win7 users at the specific Microsoft KBs that fix the issue. * MainForm.CheckForUpdatesManually pattern-matches on the result: UpToDate -> existing 'you're running the latest' message; UpdateAvailable -> existing install confirmation; UpdateCheckFailed -> NEW dialog (ShowUpdateCheckFailedDialog) whose wording is tailored to the FailureKind. The SecureConnection branch explicitly names KB3140245 and KB4474419 and offers the manual zip-install URL as a fallback. All branches keep the technical detail out of the dialog and route it to the log instead. * Background and startup polls stay silent on UpToDate and UpdateCheckFailed (no point nagging the user about something they can't act on from a timer tick), but the startup-poll log now records the failure kind and detail instead of mislabelling the outcome as 'up to date'. No version bump - this rides along with the next feature release (planned v3.2 with the Reaper ReaStream integration). The bug is silent on the affected users today, and shipping a v3.1.2 just for the error-message improvement would mean another update cycle for everyone for marginal benefit.

Bump to v3.1.1: tray tooltip 'starting up' could get stuck after first launch
Bug: if v3.1 installed via auto-update on a profile with StartMinimised on, the tray icon's hover tooltip got stuck at the initial "RemSound - starting up" string. The snapshot tick was running and SetTooltip was being called every second with the live state, but Windows shell kept showing the original cached text on hover. The fix-by-workaround was a hide-then-re-show cycle which forced the shell to rebuild the icon registration with the latest NotifyIcon.Text. Root cause: NotifyIcon.Text values set BEFORE the icon's first NIM_ADD (i.e. while Visible=false) become the shell's "initial" tooltip when the icon eventually appears. Subsequent NIM_MODIFY calls from text changes DO propagate, but the shell tends to keep showing the original text on hover - presumably a tooltip-cache eviction quirk. In the resume-after-update-with-StartMinimised flow, the window briefly shows then BeginInvokes a Minimize that flips Visible=true before the snapshot timer has had a chance to fire, so the shell registers with the stale "starting up" string. Fix: drop the hard-coded "starting up" initial text from the controller ctor entirely. The controller now takes a Func<string> buildTooltip callback from MainForm and calls it in Minimize() right before flipping Visible=true, so the shell's NIM_ADD sees current live state instead of a stale string. The 1 Hz snapshot tick keeps working for ongoing live updates while the icon is visible. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com> |

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.

Bump to v3.0.2: fix slow native-memory leak on the receive side
Bug: Andre reported audio latency feeling laggier after long sessions
on his Win10 desktop receiving Opus from his laptop. His 23-hour log
showed working set climbing from 83 MB at startup to 3.5 GB at the
end, with the managed heap staying tiny (~5-7 MB) the whole time.
CPU climbed alongside (from steady-state ~7% mid-session to peaks of
~60% by the end) and audio threads ended up doing ~4x the work they
did at the start. Andre's perception of latency drift was the CPU
pressure showing up in audio scheduling, not the buffer itself
growing (bufAvg stayed roughly stable at 25-28 ms).
Root cause: Concentus.Native (introduced in v2.2 / shipped in v3.0)
returns concrete NativeOpusDecoder / NativeOpusEncoder objects that
implement IDisposable and own native libopus state. Three call sites
were taking the IOpusDecoder / IOpusEncoder interface reference and
never calling Dispose:
* StreamSession.Dispose — comment literally said "IOpusDecoder has
no Dispose; nothing else to free", which was correct for the
pure-managed Concentus.OpusDecoder pre-v2.2 but stopped being
correct the moment we added the native binding
* OpusEncoderState.Dispose — same misleading comment, same bug
* SenderLane.OnCodecChanged — overwrote the existing encoder field
without disposing the old instance on codec change
Compounding factor: Program.Main sets GCSettings.LatencyMode =
GCLatencyMode.SustainedLowLatency to keep audio scheduling smooth
(it suppresses gen2 collections). That's correct for the hot path
but it ALSO suppresses the finalizer pass that would have released
the leaked native handles as a backstop. Because the managed heap
stayed tiny, the GC never saw enough pressure to force a gen2 pass
on its own, and the native state piled up indefinitely. Multi-output
receive multiplied the per-output growth.
Fix is in two parts:
1. Call (... as IDisposable)?.Dispose() at every release point —
StreamSession.Dispose, OpusEncoderState.Dispose,
SenderLane.OnCodecChanged before overwrite, AudioRecorder's
Concentus.Oggfile-backed OpusOggFileWriter.Dispose. The
as-IDisposable cast handles both the native and the pure-managed
path transparently (managed-only IOpusDecoder isn't IDisposable;
the as-cast yields null and the null-conditional is a no-op).
2. Periodic native-memory reaper in MainForm.SnapshotLogIfDue — once
every 300 snapshot ticks (~5 min), run
GC.Collect(2, Optimized, blocking, !compacting) +
WaitForPendingFinalizers on a background Task.Run so the gen2
work doesn't hitch the UI thread. Audio threads are separate and
unaffected. Serves as belt-and-braces for any future code path we
forget to wire and for cleaning up any per-call native scratch
the underlying library might accumulate that isn't owned by a
single .NET wrapper.
Expected behaviour after fix: working set settles around 100-200 MB
on a typical receive session and holds roughly flat for as long as
the app stays running. CPU stays at its early-session baseline
across multi-hour sessions. Andre's "latency drift" symptom should
disappear.
Wire format unchanged; same codec list, same UI, same defaults.
v3.0.2 talks to other v3.0.x peers exactly as v3.0 / v3.0.1 do.

Bump to v3.0.1: move UPnP discovery off the UI thread (fixes hang on Andre's network)
Bug: ticking the "Automatically open my router for incoming connections (UPnP)" box in Preferences could freeze the WinForms message pump until Mono.Nat's NatUtility.StartDiscovery() returned. On Andre's setup it never did — audio kept flowing (audio threads are independent of the UI thread) but the window stopped repainting, the system-tray hotkey stopped responding, and the only way out was Task Manager. Pre-existing latent bug in the v2.1 UPnP code; we just shipped without anyone exercising the path on a problematic network (multiple adapters / VPN / SSDP-swallowing router). Fix: three call sites moved off the UI thread via Task.Run - * MainForm OnShown (startup re-enable from saved AppConfig.UpnpEnabled) * MainForm Preferences applyUpnpEnabled callback (user ticks the box) * MainForm power-resume handler (Refresh() after sleep/wake) RouterPortMapper.Start() returns "immediately" only when StartDiscovery returns quickly; on a slow network it can block synchronously for many seconds. Same is true of Stop()'s socket teardown and Refresh()'s teardown-then-restart sequence. All three are now safely backgrounded. StatusChanged is unaffected - it already fires on the mapper's own thread and the PreferencesDialog handler BeginInvokes back to the UI thread. Live status label updates correctly during the new background discovery. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com> |

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.

Bump to v2.2.0: Opus native binding, efficiency tidy-up, diag self-meter
Single biggest change: added the Concentus.Native NuGet package. Concentus 2.0+ auto-detects native libopus at runtime and routes encode calls through it; encoder state lives on the C side and is reused across calls rather than `new`ing ~15 working buffers per call (Concentus issue #22, open since 2018). Measured on the desktop test at 15:36:55 — Opus 10 ms allocation rate dropped from 4,625 KB/s to 108 KB/s, a 97.7% reduction. Process CPU dropped from 4.7% to 1.6% in the same config. Audio is bit- for-bit identical (it's literally the same encoder, just better packaged). `OpusEncoderState.cs` itself unchanged on the call site. Diagnostic / measurement layer (gated on Enable-logs, zero cost when off): * ProcessSelfMeter: CPU%, managed heap MB, working set MB, allocation rate per second, GC counts per generation * Per-thread work-time counters: captureMs / sendMs / recvMs / renderMs expressed as milliseconds of CPU consumed by each audio thread per second * Inter-packet arrival gap measured at the user-space UDP socket (rxNetGapMs) — pinpoints whether arrival jitter is in the network or our own dispatch path Small efficiency wins (each one was small but cumulative): * deviceRefreshTimer interval 1s -> 3s (item 4) * WaitHandle array allocations eliminated in MixingEngine.MixLoop and MultiOutputPlayout.ProduceLoop (item 6) * MultiOutputPlayout caches its output-buffer snapshot and only rebuilds on SetOutputDevices, instead of rebuilding every 10 ms (item 7) * HeartbeatService reuses an outbound ping byte[] instead of allocating per send (item 14) * PeerDiscoveryService caches broadcast addresses and invalidates on Windows' NetworkChange event instead of walking all NICs every 1.5 s (item 16) Legacy / dead-code removal: * KeepAlive packet's implementation (struct, enums, writer, reader, size constant) — all dead since HeartbeatService landed 2026-05-06. Kept the RemPacketType.KeepAlive enum value and silent-drop dispatch for wire compat with any pre-2026-05-06 build still in the wild (item 30) * driftDropFramesTotal / driftRepeatFramesTotal fields and accessors — Phase-2 splice corrector relics, never incremented since Phase-4 resampler design landed; backed five always-zero diag log columns (items 34 + 35) * DriftAccumulator (always returned 0) — same shape, removed alongside the driftAcc= column (item 35) * TakeMaxFanOutCacheBytes / Ms + fanCacheMs column — FanOutSource was retired in May (item 36) Project documentation: * RemSoundefficiency.md added as the canonical record of the efficiency analysis, every item's status, and the measured wins from this round * Honest item-by-item review of the original 50-item list — several items I had sized optimistically in the original analysis turned out to be already-done (item 20), already-optimal (item 22), or below the meter floor (items 9, 15, 17, 25). Recorded so future passes don't re-investigate. Wire format and audio pipeline unchanged from v1.5 onward — v1.5 through v2.2 peers interoperate. |

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. |

Bump to v1.6.0: peer-address recovery, reconnect crash, long-run memory/CPU leak
Three reliability fixes. Wire format and audio pipeline unchanged from v1.4 / v1.5 — all interoperate. Peer address recovery: * When a tracked peer goes Unreachable (its resolved address — often a stale DNS / Pi-hole record, or a peer that rebooted onto a new IP) but the same peer is still heartbeat-pinging us from a different address, RemSound now adopts the live address instead of transmitting to a dead one. HeartbeatService records untracked ping sources; MainForm's TryAdoptLiveHeartbeatAddress (1 Hz) re-points the sender, heartbeat tracking and receiver allow-list. Conservative: fires only on the unambiguous one-unreachable-and-one-source case, private-range (RFC1918) addresses only so a relay can't hijack the sender, 10 s cooldown. Reconnect crash: * Fixed IndexOutOfRangeException in MainForm.SyncConnectedList. A churny peer-list rebuild (peer reboot) left SelectedIndex pointing past the rebuilt item array; the 1 Hz status timer read SelectedItem and crashed the app. New SafeSelectedItem bounds-checks the index; applied to all three timer-driven sync methods. The status tick is also wrapped in try/catch so a transient WinForms hiccup logs instead of crashing. Long-run memory / CPU leak: * A receiver left running for hours grew to gigabytes and climbing CPU. Decoder sessions orphaned by peer reconnects were not reaped — every reconnect mints a fresh (endpoint, streamId) key, and PruneIdleSessions silently skipped sessions whose PlayoutEngine lookup missed. Rewrote it to reap on each session's own LastWriteUtc (no cross-dictionary lookup), added a hard MaxLiveSessions cap as a backstop, and a "stream sessions live: N" diagnostic line. Bounds both memory and render-thread CPU. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com> |

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. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com> |

Recording-settings dialog rework + menu mnemonic clean-up
Recording settings dialog
=========================
Promote what were row attributes inside the format-attributes table
into their own dedicated listboxes. Pre-rework each format's
attribute list contained a row per (quality knob × channel mode)
combination — doubling the row count for no real benefit. WAV had
6 rows, MP3 / OGG-Opus had 8, FLAC had 4. Channel mode is now its
own listbox; per-format attribute lists shrink to 3 (WAV), 4
(MP3 / OGG-Opus), 2 (FLAC).
FLAC compression level was previously a hidden RecordingSettings
field locked at the libFLAC default of 5. Now exposed as its own
conditional listbox with all 9 levels (0..8). Visible only when the
selected file format is FLAC; the column collapses to 0% width
otherwise so the dialog reads cleanly as 4 columns for non-FLAC
formats and 5 for FLAC.
Mnemonics:
* Source Alt+S (unchanged)
* File format Alt+F (unchanged)
* Attributes Alt+A (unchanged)
* Compression Alt+L (new, FLAC-only visible)
* Channels Alt+C (new)
* OK Alt+O (unchanged)
* Cancel Alt+N (was Alt+C — moved to free C for Channels)
Record menu mnemonics
=====================
Item mnemonics inside the Record menu reorganised so the keystroke
inside the menu matches the same letter used for Ctrl+R outside it,
and Settings reads naturally:
* Start recording / Stop recording Alt+R (was Alt+S)
* Recording settings Alt+S (was Alt+T)
* Open recordings folder Alt+O (unchanged)
* Change recordings folder Alt+C (unchanged)
UpdateStartStopRecordingMenuLabel keeps the underline on a literal
R in both states ("Sta&rt recording" → "Stop &recording") so the
keystroke does the same job regardless of which label is active.
No version bump — the running version stays at 1.3.0. These changes
will be bundled with the next public release alongside whatever else
is in flight.

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.

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.
