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.

Ships the dialog reorganisation and mnemonic adjustments from
commit 45b709d. No wire-format or audio-pipeline changes — v1.3 and
v1.4 peers interoperate.
About dialog gets a v1.4 release-notes block; csproj Version
property bumped 1.3.0 → 1.4.0; RELEASE_NOTES.md rewritten with the
v1.4 highlights and a one-paragraph upgrading-from-v1.3 note (clean
auto-update via Help → Check for updates is now expected to work on
Dropbox-installed copies since v1.3's helper hardening took effect).

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.

Anyone on v1.0 / v1.1 / v1.2 in a Dropbox-synced folder will hit the
auto-updater bug v1.3 fixes — but the fix lives in the running
version's helper, so their installed binary can't use it. Adds a
prominent "Already on an older version and inside a Dropbox folder?
Read this first" section at the top of the release notes with the
manual-install steps, and renames the existing install steps to
"Install (clean machine)" for clarity.

v1.2's self-updater silently failed when the install folder lived
inside a Dropbox sync path. Dropbox held write locks on the existing
RemSound.exe / DLLs during the brief window between the parent exiting
and the helper script copying the new files in. The helper's robocopy
(/R:5 /W:1) gave up after 5 seconds, and the helper then
unconditionally relaunched the OLD binary — so the user saw the same
version they started with after pressing "Yes" on the install prompt,
with no visible error.
Helper script (BuildInstallScript) changes:
* Robocopy retries bumped to /R:60 /W:1 — up to 60 seconds per file.
Dropbox lock release happens reliably within that window in
practice.
* Robocopy exit code is captured and checked. Codes >= 8 are real
failures. On a failure the helper writes update-failed.txt to the
install folder with the cause + recovery steps, leaves the staging
folder intact, and does NOT relaunch the old binary. Earlier
versions silently relaunched the unmodified old binary, hiding the
failure.
* Helper appends a step-by-step trace to _update-helper.log (in the
install folder), with robocopy's own output included via /LOG+:.
* update-failed.txt, _update-helper.log, and _apply-update.cmd are
added to the /XF exclusion list so the helper's own state files
don't get copied to themselves on a repeat update run.
DownloadAndStageInstallAsync also clears any stale update-failed.txt
at the start of every new attempt, so a successful run leaves the
install folder clean.
readme.html "If install fails" section expanded with the new
update-failed.txt marker file behaviour and the _update-helper.log
location.
Wire format, audio pipeline, and recording feature unchanged from
v1.2 — this is updater-machinery-only.

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.

Adds a v1.1 block above the existing v1.0 block in the About dialog,
covering the priority-mode feature, always-on network packet priority,
larger UDP kernel buffers, MMCSS Critical bump, and the logging-toggle
bug fix. Version property in the .csproj bumped from 1.0.0 to 1.1.0 so
the About dialog heading and the self-updater's CurrentVersion both
report 1.1.
Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
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.
