…y fixes
- src/experiments/mr1ch.{html,js}: standalone 1ch MediaRecorder research
experiment — direct mic capture, exposes the start-timing bias that the
2ch experiment eliminates; linked from src/index.html
- demo: new "MediaRecorder 1ch" panel showcasing
recording-mode="mediarecorder-1ch" (multi-run, aggregates, Chrome 78
baseline), mirroring the AudioWorklet panel
- src/experiments/mr2ch.js: AudioContext-before-getUserMedia ordering,
MediaRecorder.stop() safety in catch path
- README: docs site link, npm-safe absolute image URLs, Node version
wording (18+ minimum, 22 via .nvmrc, 24 in docs CI)
- docs: index.md snippet now creates AudioContext before getUserMedia;
install.md Node requirement aligned with package engines field
- agents docs: prepublishOnly claim corrected, draft-notice guidance
marked resolved, session handoff updated

Summary
New: MediaRecorder 1ch research experiment
src/experiments/mr1ch.html+mr1ch.js— standalone single-channel MediaRecorder experiment for comparison againstmr2ch. Records the mic directly frominputStream, plays the MLS reference toac.destination, and cross-correlates the decoded recording against the pre-generated MLS buffer. Deliberately exposes the start-timing bias betweenMediaRecorder.start()andnoiseSource.start()that the 2ch experiment eliminates.src/index.htmlunder Experiments.New: "MediaRecorder 1ch" demo panel
demo/js/mr1ch.js+demo/index.html— ninth demo panel showcasingrecording-mode="mediarecorder-1ch"(multi-run with aggregates), mirroring the AudioWorklet panel. Panel copy documents when to use the fallback (stereo→mono downmix in the default mode) and warns that measurements contain an unknown start-timing bias, not directly comparable with the 2ch or AudioWorklet panels. Respects the demo's Safari 14 / Chrome 78 syntax baseline.Fixes
