  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.
