# Original candidate sound examples · educator review required

These mono 16-bit PCM files are synthesized sine pulses created for this pack; they contain **no** voice, song, borrowed sample, recording of a child or culturally identified rhythm. They are optional and **not cleared for classroom playback** until a local educator listens to each file on intended equipment at a comfortable setting, checks stop/playback control, and offers a no-sound route. A measured file peak below 12% of 16-bit full scale is not a guarantee of comfortable acoustic volume. Keep speakers away from ears. No learner needs a device or sound.

| File | Exact planned event transcript | Complete no-sound route |
| --- | --- | --- |
| [cue-e-slow-four.wav](cue-e-slow-four.wav) | 330 Hz short gentle tone begins at 0.10, 0.60, 1.10 and 1.60 seconds; 0.50 seconds between starts; four events, with silence between and after. | Point to four numbered X places at a slower *regular* pace; show the longer equal-gap strip, then let the child plan a four-place score. |
| [cue-f-quick-four.wav](cue-f-quick-four.wav) | 330 Hz short gentle tone begins at 0.10, 0.40, 0.70 and 1.00 seconds; 0.30 seconds between starts; same four events, with silence between and after. | Point to the same four X places at a quicker *regular* pace; show a shorter equal-gap strip, then compare counts. |
| [cue-g-first-accent.wav](cue-g-first-accent.wav) | 330 Hz short tones at 0.10, 0.60, 1.10 and 1.60 seconds; first tone has larger digital amplitude than the following three. Four events remain. | Keep four X cards and put one outlined tactile/printed star over count 1. Name it a *planned* gentle emphasis, not an observed audible accent. |

Each file is 2.10 seconds at 22,050 samples/second. The no-sound route addresses the notation and planning target. It does **not** establish aural discrimination. If the local educator approves and offers sound, record only what was actually played and what the child actually expressed or did. No looping or automatic playback is required.
