## WebRTC Auto Gain & Noise Suppression
This PR adds support for WebRTC Auto Gain and Noise Suppression as previously implemented in the Wyoming Satellite project.
### What's New
Two new entities have been created a number slider for gain and another one for noise suppression. The processing happens inside of the `webrtc.py` file and is implemented in the `__main__.py` file's `process_audio` function. The slider for gain has a limit of 0-31 and noise suppression has a limit of 0-4.
The Auto Gain and Noise Suppression persist through restarts and are saved as preferences. The values are dynamically chnged without needing a restart.
CLI flags called `--mic-auto-gain` and `--mic-noise-suppression` have also been added.
> When both values are 0, WebRTC processing is bypassed entirely with no performance overhead.
Closes#25
### Testing
When saving the audio recorded by LVA there is a noticeable increase. The following two files have been recorded with similar audio being played through them with these results (Gain-31 and NS-4):
| Metric | With AGC+NS | Without |
|---|---|---|
| Max amplitude | 0.329 | 0.054 |
| RMS amplitude | 0.008905 | 0.002862 |
| Volume adjustment needed | 3.034x | 13.479x |
| Rough frequency | 916 Hz | 705 Hz |
* bugfix: supress first end of file event and only callback on second one
* add some notes on testing
* fixed tts.speak
* fix unduck after timer end
* use custom docker-entrypoint on dev container
* change mv to copy in the docs when using .env file
Home Assistant sends MEDIA_PLAYER_COMMAND_STOP when the queue is cleared.
The MediaPlayer entity did not handle this command, causing playback to
continue without media metadata and leaving the UI in an inconsistent state.
This change adds explicit handling for the STOP command:
- stop playback via the music player
- reset the media player state to IDLE
This aligns the behavior with the original player and Home Assistant’s
expected media player semantics.
