fix(voice): prepend silence to TTS audio to prevent first-word clipping#29
Conversation
…clipping PulseAudio's module-suspend-on-idle suspends the WSLg RDPSink after inactivity. When new audio starts playing, the sink takes ~200-500ms to wake up, causing the first words to be clipped. Use ffmpeg's adelay filter to prepend 300ms of silence to the MP3 before playback. Applied to both single-shot and first-chunk of chunked TTS. Falls back gracefully if ffmpeg is unavailable.
