# Page Turn candidate audio · full transcript and clearance

**HUMAN LISTENING NOT DONE / DEVICE NOT APPROVED / LOCAL VOLUME NOT APPROVED.** These original **computer-created** model files are **not cleared** for learner playback. A human educator must preview each **whole file**, including leading/trailing silence, on the actual intended device at a locally approved comfortable room volume, review access/stop/pass choices and confirm exact use. No forced listening, headphones, quiet response, singing or pitch matching. Digitally bounded samples do not establish acoustic safety, comfortable sound, a child's hearing or live performance. Use exact score/source/raised **no-sound** access meanwhile. Reviewed live familiar sound is a separate gate.

## Original named work and purpose

[Page Turn source/purpose](../SUPPLIED-WORK.md) and [actual source card](../print/work-source.pdf) identify an original SubjectNest teaching model, © NeuroForgeIO Pty Ltd 2026, CC BY 4.0. Documented author purpose: model repeated four-beat backing under change in another part so teachers/learners can inspect and try own tiny duos. No named human composer/performer, recorded person, borrowed music, cultural tradition, community importance, actual library use or proved effect. Isolated parts are study extracts of the same model. Reading/transcribing the resource does not prove that sound was heard or a child performed it. A learner's actual score/source response supports only narrow partial author-purpose exploration; wider contexts need varied appropriate sources.

## Full onset transcript

Each file is **4.4 seconds**, mono signed 16-bit PCM, **22,050 Hz**, 97,020 frames. Both rounds have four beats; local numbers restart 1–4. Global beat starts **0.20, 0.70, 1.20, 1.70, 2.20, 2.70, 3.20, 3.70 seconds**. Beat spacing **0.50 seconds** is production metadata, not a required learner speed. Each event is **0.20 seconds** with **0.012-second** onset/offset fades. Sources/pitch/tone gains stay fixed: A = 330 Hz sine at 0.014 gain; B = 330 Hz fundamental plus 660 Hz half-strength harmonic at 0.010 gain. They are different synthesized timbres at one pitch anchor, not recorded instrument/person identities. Simultaneous A+B on one start is two individual events in one active region.

| Candidate | All A onsets in seconds | All B onsets in seconds | Complete sound/wait score |
|---|---|---|---|
| [Page Turn](page-turn.wav) | 0.20, 1.20, 2.20, 3.20 | 0.70, 1.70, 2.20, 3.70 | A first 1,3 / second 1,3; B first 2,4 / second 1,4. Eight individual events, seven active regions; both at global 5, neither at 6. |
| [Backing alone](backing-alone.wav) | 0.20, 1.20, 2.20, 3.20 | none | A sound/wait/sound/wait in each round; B waits all eight. Four events; exact A repeat. |
| [Changing part alone](changing-alone.wav) | none | 0.70, 1.70, 2.20, 3.70 | A waits all eight; B wait/sound/wait/sound then sound/wait/wait/sound. Four events; B changes local 1/2. |

## Full event-end and silence transcript

**Page Turn:** A events 0.20–0.40, 1.20–1.40, 2.20–2.40, 3.20–3.40. B events 0.70–0.90, 1.70–1.90, 2.20–2.40, 3.70–3.90. Exact silence regions 0.00–0.20, 0.40–0.70, 0.90–1.20, 1.40–1.70, 1.90–2.20, 2.40–3.20, 3.40–3.70, 3.90–4.40. Two coincident events at 2.20 have separately specified A/B tones. Nothing sounds at global 6 (2.70). There is no speech, lyric, count-in, metronome, music bed or hidden later sound.

**Backing alone:** events 0.20–0.40, 1.20–1.40, 2.20–2.40, 3.20–3.40. Exact silence 0.00–0.20, 0.40–1.20, 1.40–2.20, 2.40–3.20, 3.40–4.40. No B/no other content.

**Changing alone:** events 0.70–0.90, 1.70–1.90, 2.20–2.40, 3.70–3.90. Exact silence 0.00–0.70, 0.90–1.70, 1.90–2.20, 2.40–3.70, 3.90–4.40. No A/no other content.

The original computer model and exact transcribed plan are reproducible and signal-checked, **not human-listened or classroom piloted**. Fresh checks use different scores and no matching file. A listening clearance, actual resource encounter, child response, live maker/maintained beat/independence and actual audience receipt are separate records.

## Human clearance record · all blank/held

| Required field | Current state |
|---|---|
| Exact file/hash, reviewer/date and whole-file preview | HUMAN LISTENING NOT DONE |
| Intended device/speaker/room and access review | DEVICE NOT APPROVED |
| Comfortable local volume, stop/pass and willing learner choice | LOCAL VOLUME NOT APPROVED |
| Full transcript match/unexpected sound/comfort observation | NOT OBSERVED BY HUMAN |
| Allowed use/limits and decision owner/review date | NOT CLEARED |
| Actual learner encounter/response, maker or audience | UNOBSERVED; never inferred from clearance |

[Exact no-sound alternatives](../print/TEXT-ALTERNATIVES.md) provide every sound/wait/undecided mark and printed source word. Child can direct broad/raised rows or silent readers. Do not automatically play, loop, normalize or assign headphones. Regeneration is deliberate; human clearance needs the exact regenerated hash and intended setting, not an earlier different file.
