description <<~EOT
Audio player configuration (JSON with four keys):
command – Shell command that receives raw PCM on stdin.
Opened via IO.popen(cmd, "w"); the playback thread
writes audio bytes and silence chunks to its stdin.
Default: ffplay s16le 24 kHz mono pipe.
frequency – Sample rate in Hz (e.g. 24000). Used to compute
the byte size of silence chunks: frequency ×
(bits / 8) × pause.
bits – Bit depth per sample (e.g. 16). Determines bytes
per sample for silence chunk calculation.
pause – Seconds of silence injected when the audio queue
is empty. Prevents the playback process from
seeing EOF and hanging. Also the sleep duration
between silence writes.
