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 v3.0.0: 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 v1.5.0: 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.

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.
