| audio_recorder->record |
|video_writer]to, this replaces the audio of
audio_recorder<-sound.
Otherwise the samples are written to to while recording, as
described above. If to is a video_writer, the samples are
added to its audio using video_writer->append_audio.
If the video_writer has no audio yet, it gets an audio track with the
frequency and channels of the recorder.
