* fix(audio): a sound is voice only with a voice-range pitch, judged on the whole clip Two ways the kind guess called a non-voice sound voice: - A short hit, click or whoosh can have a speech-shaped envelope. classify() now also measures the share of 40 ms frames with a 70-500 Hz fundamental (YIN, moved from the CLI into core) and calls a sound voice only when that share reaches 0.15. Speech measured 0.22-0.43; impacts, clicks and whooshes 0. - A range query judged a clip's kind on the slice it covered, so 1.7 s of a music bed read as voice. A film clip's kind is now judged on all of the clip that plays. Even-paced speech (a 64 s TTS take) moves less at syllable rate and was called music; with no beat and a voiced share of 0.25 or more it is now voice. * chore(audio): keep each touched file's comment share at or under its base The Comments check failed on run.ts, targets.ts and audioAnalysis.ts because the PR added comment lines to files whose share may only go down. Drops the added doc comments; no code change. — Jerrai * fix(audio): preserve clip evidence and stereo pitch during analysis * fix(audio): bound and cache whole-clip kind analysis * fix(audio): retain native-rate kind evidence when available --------- Co-authored-by: Jerrai <jerrai@heygen.com>
