# Optional original WAV demonstrations

These mono, 22,050 Hz, 16-bit PCM files sound the exact event sequences in `scores.json` at 96 quarter-note beats per minute. They use pure sine tones, with a short fade to avoid clicks. They are demonstrations, not intended as expressive recordings. A device is never required: use printed notation, voice, desk taps, raised blocks or the exact text route. Playback may differ in loudness across devices; keep volume comfortable.
