HUMAN LISTENING NOT DONE / DEVICE NOT APPROVED / LOCAL VOLUME NOT APPROVED. Three original computer-created candidates not cleared for learner playback. A human educator previews each whole file on intended device/comfortable locally approved volume, silence/access/willingness/stop/pass, records exact hash/date/allowed scope before playback. Digital levels not acoustic safety/comfort/hearing evidence. Exact source/score/raised no-sound route available; actual quiet live making separately needs exact familiar source/technique/space/willing maker review. No compulsory voice/headphones/body/public performance or automatic playback.
Accurate work and purpose
Back to the Start/source card, original SubjectNest computer-created teaching model, © NeuroForgeIO Pty Ltd 2026, CC BY 4.0. Documented purpose model last-bit-first rhythm so children make/direct an own tiny there-and-back piece. Same fixed single pitch/source throughout; not a melodic tune, reversed waveform, human recording/performance or cultural/community work. No named human composer/performer, borrowed sound, community importance/tradition, actual scene use/achieved effect. Part extracts are computer studies. Actual supplied encounter/child response narrow author-purpose FE01; broader contexts need varied appropriate actual sources.
Full score/onset transcript
Each file 5.4 seconds, mono signed 16-bit PCM 22,050 Hz, 119,070 frames. Ten shared starts 0.20/0.70/1.20/1.70/2.20/2.70/3.20/3.70/4.20/4.70s; 0.50 seconds spacing production data, not learner speed target. FIRST shared 1–5/BACK 6–10, each five local sound/wait decisions. Every event 0.20 seconds, 0.012-second fades, fixed 330 Hz sine gain 0.014/unchanged source/level/pitch. No 660 Hz part change, speech, lyric, cue, count-in, metronome/music bed. Waveforms generated forward normally; only decision order reverses.
| Candidate | Every FIRST onset in seconds | Every BACK onset in seconds | Full planned score |
|---|---|---|---|
| Back to the Start (playback review held) | 0.20, 1.20, 1.70 | 3.20, 3.70, 4.70 | FIRST sound/wait/sound/sound/wait at local 1,3,4; BACK wait/sound/sound/wait/sound at local 2,3,5/shared 7,8,10. Six short events, all five reverse correspondences including waits. |
| FIRST alone (playback review held) | 0.20, 1.20, 1.70 | none | FIRST local/shared 1,3,4, waits at 2,5; BACK waits all five. Three events, first phrase study, not full reversal performance. |
| BACK alone (playback review held) | none | 3.20, 3.70, 4.70 | FIRST waits all five; BACK local 2,3,5/shared 7,8,10, waits local 1,4/shared 6,9. Three events, back phrase study, not full reversal performance. |

Whole model: FIRST events 0.20–0.40/1.20–1.40/1.70–1.90; BACK events 3.20–3.40/3.70–3.90/4.70–4.90. Silence 0.00–0.20/0.40–1.20/1.40–1.70/1.90–3.20/3.40–3.70/3.90–4.70/4.90–5.40. Whole waits shared 2,5,6,9. FIRST grouping ends 2.70, whole last beat ends 5.20, neither has an audible stop/cue.
FIRST alone: events 0.20–0.40/1.20–1.40/1.70–1.90. Silence 0.00–0.20/0.40–1.20/1.40–1.70/1.90–5.40. No BACK/hidden content.
BACK alone: events 3.20–3.40/3.70–3.90/4.70–4.90. Silence 0.00–3.20/3.40–3.70/3.90–4.70/4.90–5.40. No FIRST/hidden content.
No extra content outside these events. Signal/full-score/transcript checks not human-listened or classroom piloted. Fresh prescribed sources have no matched sound. Clearance not actual child aural/reversal heard/scoped rhythm-entry/performance/audience/year attainment. Chosen one-phrase Music making/whole optional separately observed; direct adult sound adult performance, silent plan not performance.

Exact alternatives preserve every sound/wait/local/shared decision and source/portfolio word. No automatic playback/loop/normalisation/headphones; changed/regenerated file requires exact new-hash human/device/local-volume review. Earlier file approval cannot transfer.
