Key Highlights
- Introduce SafePipe for thread-safe IPC
- Add audio normalization to scale input to –0.95 dBFS
- Overhaul callbacks to run asynchronously via helper threads
- Add wakeword_backend config and faster_whisper_vad_filter flag
- Embed nanosecond-precision timestamps in metadata
New Features
- Thread-safe IPC (SafePipe)
- Audio normalization
- Asynchronous event callbacks
- Wake word and VAD configuration options
- Rich metadata with timestamps
- CLI enhancements for VAD and debugging
Full Release Notes
# RealtimeSTT 0.3.103 ### Features & Improvements - **Thread‑safe IPC**: Introduce `SafePipe` to replace `mp.Pipe`, hopefully ensuring robust inter-process communication (needs more tests). - **Audio normalization**: New `normalize_audio` option scales input to –0.95 dBFS for consistent transcription quality. - **Callback overhaul**: All event callbacks (VAD, wake‑word, turn detection, recording, realtime updates) now run asynchronously via helper threads. - **Wake word & VAD**: Add `wakeword_backend` config and `faster_whisper_vad_filter` flag; improved error messages when misconfigured. - **Rich metadata**: Embed nanosecond‑precision timestamps in both client and server, serialized as formatted strings. - **CLI enhancements**: `--faster_whisper_vad_filter` and `--debug_websockets` flags give finer control over server behavior. - **Testing updates**: Adjusted parameters in `realtimestt_test` and added a new `type_into_textbox.py` example.
