"""Shared audio utilities for Reachy Mini apps.

Pluggable, mirroring `vision/`:
- `AudioFeatures` + `AudioSource` protocol (`base`)
- `FFTBeatAnalyzer` — pure FFT band + beat/BPM core (`analyzer`)
- `MicAudioSource` — live capture via sounddevice, degrades clean (`capture`)
- `SilentAudioSource` — no-device fallback (`base`)
- `build_audio_source(spec)` — pick a source from config (`factory`)
