Candidate only; not cleared for children. Before use a human educator must listen to every whole file on the intended device, check for clicks and comfortable room/volume conditions, record reviewer/date/device/setting/stop plan, offer exact no-sound route and respect pass. Current status: HUMAN LISTENING NOT DONE / DEVICE NOT APPROVED / LOCAL VOLUME NOT APPROVED. No compulsory headphones, amplification, looping, singing, tapping, movement or recording. A cue is never a body or safety command. Programmed amplitude is not measured ear-level decibels or a comfort guarantee. No child data.
All files are original 22,050 Hz, 16-bit mono PCM, 3.2 seconds, no speech, background track or samples. The six shared place starts are 0.20, 0.70, 1.20, 1.70, 2.20, 2.70 seconds, evenly separated by 0.50 s. Each active event lasts 0.20 s with 0.012 s entry/exit fades. Line A is a smooth electronic 330 Hz sine at 0.016 of digital full scale. B is a second original electronic timbre with 330 Hz fundamental plus half-strength 660 Hz harmonic, multiplier 0.010. Source/timbre differences label the parts; pitch, level and timbre are not child variables in this pack. At a shared start the two synthesized parts are mixed, not two physical speakers. Peak is numerically checked but not a listening test.
| Candidate | Complete place-by-place onset / wait transcript | Exact no-sound score |
|---|---|---|
| Together (playback review held) | Place 1 at 0.20 s A+B; 2 at 0.70 both wait; 3 at 1.20 A+B; 4 at 1.70 both wait; 5 at 2.20 A+B; 6 at 2.70 both wait. All six individual events: A 0.20/1.20/2.20 and B 0.20/1.20/2.20. | A circles 1,3,5; B squares 1,3,5; dash waits elsewhere, six shared columns. |
| Turns (playback review held) | Place 1 at 0.20 s A; 2 at 0.70 B; 3 at 1.20 A; 4 at 1.70 B; 5 at 2.20 A; 6 at 2.70 B. All six events: A 0.20/1.20/2.20 and B 0.70/1.70/2.70. The other line waits at each place. | A circles 1,3,5; B squares 2,4,6; dash waits elsewhere, one line per column. |
| Meet then separate (playback review held) | Place 1 at 0.20 s A+B; 2 at 0.70 both wait; 3 at 1.20 A; 4 at 1.70 B; 5 at 2.20 A; 6 at 2.70 B. All six individual events: A 0.20/1.20/2.20 and B 0.20/1.70/2.70. | A circles 1,3,5; B squares 1,4,6; dash waits elsewhere. Read both / neither / A / B / A / B. |
Full silence transcript: all files are silent 0.00–0.20. Together sounds 0.20–0.40, 1.20–1.40, 2.20–2.40; silence 0.40–1.20, 1.40–2.20, 2.40–3.20. Turns sounds 0.20–0.40, 0.70–0.90, 1.20–1.40, 1.70–1.90, 2.20–2.40, 2.70–2.90; silence 0.40–0.70, 0.90–1.20, 1.40–1.70, 1.90–2.20, 2.40–2.70, 2.90–3.20. Mix sounds 0.20–0.40, 1.20–1.40, 1.70–1.90, 2.20–2.40, 2.70–2.90; silence 0.40–1.20, 1.40–1.70, 1.90–2.20, 2.40–2.70, 2.90–3.20. Faded endpoints may have zero samples within active intervals.
No-sound rows can be raised round/square tokens with dash waits or exact neutral column descriptions. They fully meet composition-plan/texture reasoning; they do not prove auditory discrimination, performed coordination, actual comfortable volume, cultural importance or audience receipt. If reviewed playback/real sound-making occurs, record cue/device/setting and the actual learner response separately. No file provides either fresh public check's layout. Owned synthesis code reproduces all bytes.
