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.
- **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.
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.
