Renames what users see. The app, the installers, the window title, the
docs and all 21 locales now say VoiceStudio, with "(previously
OmniVoice-Studio)" noted near the title of each doc surface so people
recognise it.
Deliberately NOT renamed, because renaming any of them silently breaks
an existing install — there is no legacy-path fallback anywhere in this
codebase:
- bundle identifier com.debpalash.omnivoice-studio (MSI UpgradeCode,
macOS TCC grants, managed venv, WebView localStorage, the
single-instance lock)
- data directories OmniVoice / .omnivoice and omnivoice.db
- the ~150 OMNIVOICE_* environment variables
- the X-OmniVoice-* HTTP headers (a wire protocol)
- the published Docker image paths
- the OmniVoice ENGINE, which is a model name and not this product
tests/test_identity_paths_survive_the_rename.py pins every one of those
so a future well-meaning sweep cannot orphan a user's library.
Linux .deb users install a new package name and should apt remove
omnivoice-studio; that note is in the changelog.
* feat(dictation): opt-in NLMS AEC for dictate-over-playback (Wave 8b)
Dictating while OmniVoice plays audio (TTS preview, dub, video) leaks the
loudspeaker signal into the mic, and the streaming ASR transcribes that
bleed. Browser echoCancellation varies per platform/webview — it can't be a
cross-platform default — so this adds a server-side canceller that behaves
identically everywhere.
services/aec.py ports Patter's NlmsEchoCanceller (MIT): a time-domain NLMS
adaptive filter with a Geigel double-talk detector, warm-up step ramp, and
far-end staleness pass-through. /ws/transcribe gains an opt-in '?aec=1[&sr=]'
mode: frames are raw int16 mono PCM tagged with a 1-byte prefix (0x00 mic,
0x01 playback reference); the mic is cleaned against the reference before
buffering, and the cleaned PCM is muxed via stdlib wave (not ffmpeg). Without
the param the protocol and behaviour are byte-for-byte unchanged.
Backend ships dark (no new deps — numpy already pinned); frontend far-end
streaming is a follow-up. Tests cover echo attenuation, double-talk
preservation, cold/stale pass-through, param validation, and the framing
helpers — all pure-numpy/stdlib so they skip the torch ASR stack.

* test(capture_ws): stubs accept the new pcm_sr kwarg
_transcribe_buffer/_transcribe_buffer_full gained an optional pcm_sr kwarg
for the AEC PCM path; the protocol-test stubs had fixed signatures and
raised TypeError on it, so the handler sent 'error' instead of 'final'.
Accept **kw in the stubs.
