The optional WAV timing cue is a 2.4-second, single-channel, quiet synthesized example. It contains no speech, sample, recording of a person, real traffic signal or borrowed melody. No one needs to listen or make sound to complete the Music blocks. Set playback at a comfortable level or do not play it.
| Beat | What the WAV does | Silent/tactile equivalent |
|---|---|---|
| 1 | Short low tone for about 0.18 seconds | One short raised/signed mark |
| 2 | Rest | Empty/rest card |
| 3 | Longer slightly higher tone for about 0.36 seconds | One longer raised/signed mark |
| 4 | Rest | Empty/rest card |
Beats last 0.6 seconds each. The timing and pitch contrast are examples to alter; learners can choose different original sounds, quiet taps, AAC labels, movement-free symbols or a wholly silent score. The waveform is generated locally by source code from two simple sine tones with fades, not copied from any recording. It does not convey a public safety instruction.
