# Four original electronic sound candidates · full event transcript

**Candidate only; not cleared for child playback.** An educator must listen to every whole file on the *intended* device, check click/artefact and room comfort, approve the local volume, offer a complete no-sound route and respect a child's stop/pass. Do not amplify or loop a cue to force audibility; no headphone use is required. PCM peak is a digital measurement, not a decibel at a child's ear. No child data is captured.

Each original file is **22,050 Hz, 16-bit mono PCM, 2.40 seconds**. There are four 0.20-second events beginning at **0.10, 0.60, 1.10, 1.60 seconds** with short fades and silence elsewhere. L = 330 Hz; H = 392 Hz. A = one sine component; B = 0.8 fundamental + 0.6 third harmonic, normalised in programmed RMS against A. V = very soft programmed amplitude 0.018 of digital full scale; S = soft 0.050. Those controlled recipe values do not guarantee perceptually matched pitch/source/level or safe acoustic output on arbitrary equipment.

| Candidate | Complete four-event transcript (pitch/source/level) | Exact no-sound equivalent |
| --- | --- | --- |
| [Base take](cue-base.wav) | 0.10 L/A/V; 0.60 L/A/V; 1.10 L/A/V; 1.60 L/A/V; otherwise digital silence. | Four `L A V` broad three-lane cards. |
| [One pitch edit](cue-pitch-2.wav) | 0.10 L/A/V; 0.60 H/A/V; 1.10 L/A/V; 1.60 L/A/V; otherwise digital silence. | Start from base; swap only place 2 L→H. |
| [One source edit](cue-source-4.wav) | 0.10 L/A/V; 0.60 L/A/V; 1.10 L/A/V; 1.60 L/B/V; otherwise digital silence. | Start from base; swap only place 4 A→B. |
| [One level edit](cue-level-1.wav) | 0.10 L/A/S; 0.60 L/A/V; 1.10 L/A/V; 1.60 L/A/V; otherwise digital silence. | Start from base; swap only place 1 V→S. |

The card route teaches the **planned one-edit** concept and preserves exact event information. It cannot evidence aural discrimination, controlled voice/instrument performance, comfort or audience response. Any actual trial is logged separately by cue/device/child words. These cues are not a substitute for a real arts-work encounter.
