AI Summary

This release focuses on improving the stability and robustness of RealtimeSTT by introducing thread-safe inter-process communication, audio normalization, and asynchronous event handling.

Key Highlights

  • Introduction of thread-safe IPC with the `SafePipe` class.
  • Audio normalization feature scaling input to –0.95 dBFS.
  • Overhaul of all event callbacks to run asynchronously.
  • New configuration options for wake words and VAD filtering.

New Features

  • SafePipe for robust inter-process communication
  • normalize_audio option for consistent transcription quality
  • Nanosecond-precision timestamps in client and server
  • CLI flags for VAD filtering and WebSocket 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.
