v5.2: stability and polish — deep-audit bug fixes + install-flow fixes
Verified findings from a multi-dimension code audit, plus the two install-flow bugs: - Fix Opus encoder use-after-free on a codec/rate change while streaming (guard swap vs encode). - Fix "both" single-file recording dropping audio + drifting (drain both directions in lockstep). - Fix broken clip counter, UPnP teardown on exit, auto-update-restart foreground grant, and a malformed-Opus-format packet orphaning a playout session forever. - Post-install relaunch now respects start-minimised; uninstall is path-aware so it won't clear a different copy's run-at-startup. - Perf/hygiene: cache AppConfig off UI hot paths, fold per-peer EQ+gain into one pass, deterministic disposal (tray menu, timers, COM shortcut, Process handles, process meter), ring-buffer overflow guard, receiver session-lock fix, remote-control allow-list moved onto the UI thread. - Remove dead code (two IsAsioBackend, SessionPlayout.Reset, IsSameEndpoint, RemSoundUpdater IDisposable); several stale-doc fixes. Deferred (not in this release): drift-estimator tweak, peer-discovery pruning, uninstall retry-loop, encryption nonce. Wire format unchanged (interops v3.3-v5.1). Version -> 5.2.

v3.9.1: plain/WASAPI streams now play on an ASIO-mode receiver (silent-mic fix)
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.

Release v3.7: device-change smoothing, auto-tune spike rejection, wider mic detector, forensic logging
Coalesce capture-engine rebuilds (CompositeCaptureBackend): a swap-triggering source change now arms a 250ms debounce timer and re-arms on each further change, so a flap or quick reconfiguration produces ONE rebuild to the final state instead of a burst (Andre's 16:40 four-rebuilds-in-33s crackle). In-place updates still apply immediately; a pending rebuild whose target flaps back is cancelled. Auto-tune (TickRoute) now keys off the SECOND-highest arrival-gap/render-gap second in the lookback window instead of the single worst, so a lone ~1s OS/driver stall no longer balloons the buffer to the 200ms cap (the 16:51 trim burst); sustained jitter still reacts at full speed. Logs both gap-max (true peak) and gap-used (value acted on). Mic-privacy detector widened: also catches a per-app Deny aimed at this exe under ConsentStore\microphone\NonPackaged\<exe>, the HKLM NonPackaged gate, and the Group-Policy/MDM force-deny (AppPrivacy LetAppsAccessMicrophone=2) — the block shapes that silence WASAPI capture while ASIO sails past, and that the old three-value check missed. Forensic instrumentation so the next log proves what happened: capPeak= (loudest pre-encode sample, per lane, on the diag line), mic-privacy verdict logged at startup, ui: capture tick/untick events, and device-event: lines for Windows endpoint changes. Docs: mic-privacy + auto-tune sections updated in readme.html, MANUAL.md regenerated, About-box changelog and RELEASE_NOTES for v3.7. Co-Authored-By: Claude Fable 5 <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.

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 v3.0.0: 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 v2.1.0: 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 v1.5.0: 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> |

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.
