AI Summary

This release focuses on stability and robustness, introducing thread-safe IPC, audio normalization, and an overhaul of event callbacks to run asynchronously.

Key Highlights

Introduced `SafePipe` to replace `mp.Pipe` for robust inter-process communication.
New `normalize_audio` option scales input to –0.95 dBFS for consistent quality.
All event callbacks now run asynchronously via helper threads.
Added `wakeword_backend` config and `faster_whisper_vad_filter` flag.
Embeds nanosecond-precision timestamps in client and server metadata.

New Features

Thread-safe IPC implementation.
Audio normalization feature.
Callback overhaul for asynchronous execution.
Wake word and VAD configuration improvements.
Rich metadata with nanosecond timestamps.
CLI enhancements for debugging and control.

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.
