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.

# RemSound v1.2
|
||
|
||
Recording, sound cues, and receiver-side drift compensation. The wire format and audio pipeline are unchanged from v1.1, so v1.1 and v1.2 peers interoperate.
|
||
|
||
## Highlights
|
||
|
||
- **Recording to disk.** Dedicated Record menu (Alt+O) with Start/Stop on Ctrl+R, settings dialog, per-profile source / format / bit-depth / channel-mode / folder. Pick **received only**, **sent only**, or **both** as the recording source. 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), MP3 (LAME, 128–320 kbps CBR), **OGG-Opus** (96–256 kbps VBR, reuses the Concentus encoder from the wire path), **FLAC** (pure-managed CUETools FLAKE, lossless ~50% the size of WAV). All four record at 48 kHz; labels make the rate explicit.
|
||
- **Recording start / stop sound cues.** Short audible confirmation when recording transitions on or off. Played via the default Windows output device, separate from the recording pipeline, so a normal recording does not include the cue.
|
||
- **Per-cue sound preferences.** The single "Mute connect/disconnect sounds" checkbox in Preferences is replaced by a per-cue CheckedListBox: Connect / Disconnect / Recording start / Recording stop. Old profiles with the legacy mute on are honoured automatically on first load.
|
||
- **Receiver-side drift compensation upgraded.** Continuous `WdlResampler` running at a slowly-updated rate ratio replaces v1.1's discrete single-frame splice corrector. Smooths long-session sender-vs-receiver clock drift without the occasional 21 µs splice.
|
||
|
||
## UI changes
|
||
|
||
- **Record menu moved to Alt+O.** The old `Alt+R` chord collided with the **Receive audio (Alt+R)** checkbox on the main form. Inside the menu the item mnemonics are unchanged (S / T / O / C).
|
||
- **Auto-tune interval label is mode-aware.** In BothIndependent mode the interval combo's label reads "Auto-tune interval — WASAPI and ASIO" so it's clear the same combo drives both lanes' tick cadence — each lane still independently tunes to its own latency target.
|
||
|
||
## Diagnostics (only active with Enable logs ticked)
|
||
|
||
- Per-stage discontinuity probes: sender raw-capture, sender pre-encode (per-lane in BothIndependent), receiver post-decode, post-ring-buffer, post-resampler. Lets log inspection localise where in the chain an audio click was introduced.
|
||
- Wire-level sequence tracking on each PCM stream: in-order / missed / reordered / duplicated packet counts in the diag log.
|
||
- Clipped-sample delta in the diag log.
|
||
|
||
## Bug fixes
|
||
|
||
- Auto-tune interval combo no longer greys out when only the ASIO lane's auto-tune is ticked in BothIndependent mode. Previously the combo's enabled state followed only the WASAPI checkbox.

||
## Install
|
||
|
||
1. Download `RemSound-v1.2.zip` from this release.
|
||
2. Extract somewhere with write permission (e.g. `C:\RemSound\`, `Documents\RemSound\`, etc.). Avoid `Program Files` unless you grant write permission so the self-updater can replace files in place.
|
||
3. Run `RemSound.exe`. Allow on private networks when Windows Firewall prompts.
|
||
4. Press F1 (or use the Help menu) for the user manual.
|
||
|
||
Requires the .NET 10 Desktop Runtime. If it's missing, Windows offers to fetch it on first launch.
