## Audio
Captures system audio automatically using `ffmpeg` with the PulseAudio/PipeWire monitor of your default output sink. Falls back to `parec` if available, or a built-in demo signal.
No extra packages needed — just `ffmpeg` (pre-installed on most Linux systems).
Captures system audio by opening the PulseAudio/PipeWire monitor of your default output sink directly via libavformat and libavdevice. Libraries are loaded at runtime with `dlopen` — no dev packages, no subprocess, no extra dependencies.
