- new Transcriber interface makes the recorder service engine-agnostic;
WhisperEngine (local JNI) and new RemoteWhisperEngine (POST /inference,
verbose_json, in-memory WAV upload via new WavEncoder) implement it
- SessionConfig carries serverUrl; when set, BOTH the live pass and the
final pass transcribe remotely (server owns the model, e.g. large-v3
on GPU); local engine remains the offline fallback
- UI: Transcribe on: phone/server dropdown + server URL field,
persisted in SharedPreferences; model controls grey out in server
mode; manual Transcribe also routes to the server
- network security config permits cleartext HTTP for user-configured
LAN/tailnet servers (documented; HTTPS works either way)
- WavEncoder round-trip unit test (11 total green); validated phone ->
Tailscale -> R9700 with large-v3 before the app-side change
- core/recording: MeetingRecorder (AudioRecord at the device's native
rate, WAV on disk + 60 s rolling window resampled to 16 kHz), streaming
WavWriter, thread-safe RollingWindow, linear resampler; WavReader moved
here from the app
- app: RecorderService (foreground, type microphone) with ongoing
notification and StateFlow state; Record/Stop UI with timer and level
meter; runtime permission flow; finished recordings auto-load for
transcription
- launcher icon (mic + waveform, matching the desktop brand) and
notification glyph
- fix real M0 bug caught by the new unit tests: WavReader parsed 16-bit
fmt fields (audioFormat/channels/bitsPerSample) with 32-bit reads
- JVM tests: WAV round trip, native-rate header, resampler, rolling
window — 5/5 green; assembleDebug and aapt2 APK checks pass
- validated on-device on a Fairphone 6 (Android 16): model download,
engine load, recording and transcription all working
