Candidate only; not cleared for children. A human educator must listen to every whole file on intended equipment, inspect clicks, check comfortable local volume/room, record reviewer/date/device/setting/stop plan, offer the no-sound route and honour pass before playback. Current status: HUMAN LISTENING NOT DONE / DEVICE NOT APPROVED / LOCAL VOLUME NOT APPROVED. No compulsory headphones, amplification, looping, singing, tapping, movement or recording. These are tiny original rhythm examples, never physical/safety commands. Digital amplitude does not measure ear-level decibels or certify comfort. No child data.
Each is 22,050 Hz, 16-bit mono PCM, 2.7 seconds, one original smooth 330 Hz sine source, no voice, borrowed sample or ambient track. All events are identical 0.12-second sounds, multiplier 0.018 of digital full scale, with 0.012-second entry/exit fades. Four fixed beat starts are 0.20 / 0.80 / 1.40 / 2.00 seconds, every 0.60 s. ONE sounds at beat start. PAIR sounds at beat start and 0.30 seconds later, the middle of that same beat. This file tempo is a production fact, not a required learner speed or pulse-control claim. Upper score dots represent beats and do not add another audible line.
| Candidate | Full onset and event transcript | Exact no-sound equivalent |
|---|---|---|
| ONE (playback review held) | Beat 1 ONE at 0.20; 2 ONE at 0.80; 3 ONE at 1.40; 4 ONE at 2.00 s. All four events have the same short 330 Hz source. Four beats/four events. | Four broad ONE cards: first raised disc/middle dash in each, separate fixed beat-start tags. |
| PAIR (playback review held) | Beat 1 events 0.20,0.50; beat 2 0.80,1.10; beat 3 1.40,1.70; beat 4 2.00,2.30 s. All eight events have the same short source. Four beats/eight events, same beat-start pace as ONE. | Four broad PAIR cards: first then middle raised disc in each, separate fixed beat-start tags. Never stack the pair simultaneously. |
| Mixed (playback review held) | Beat 1 ONE at 0.20; 2 ONE at 0.80; 3 PAIR at 1.40,1.70; 4 PAIR at 2.00,2.30 s. All six events use the same short source. Four beats/six events. | ONE ONE PAIR PAIR: 1/1/2/2 raised discs by beat, middle dashes in first two, separate fixed beat-start tags. |
Full sound/silence intervals: all are silent 0.00–0.20. ONE sounds 0.20–0.32, 0.80–0.92, 1.40–1.52, 2.00–2.12; silence 0.32–0.80, 0.92–1.40, 1.52–2.00, 2.12–2.70. PAIR sounds 0.20–0.32, 0.50–0.62, 0.80–0.92, 1.10–1.22, 1.40–1.52, 1.70–1.82, 2.00–2.12, 2.30–2.42; silence 0.32–0.50, 0.62–0.80, 0.92–1.10, 1.22–1.40, 1.52–1.70, 1.82–2.00, 2.12–2.30, 2.42–2.70. Mixed sounds 0.20–0.32, 0.80–0.92, 1.40–1.52, 1.70–1.82, 2.00–2.12, 2.30–2.42; silence 0.32–0.80, 0.92–1.40, 1.52–1.70, 1.82–2.00, 2.12–2.30, 2.42–2.70. Faded endpoints may contain zero samples inside active intervals. No other event is present.
The score, exact neutral description or raised cards fully meet the planning/subdivision goal without sound. They cannot prove actual aural discrimination, comfortable making, performed beat/midpoint control or audience receipt. A neutral adult pointer can keep visible beats during approved playback if useful; record the child's actual heard route/response separately. No file supplies either fresh check's full source or final layout. Owned synthesis source reproduces all bytes.
