Xuanru LiandJerrai 1df31d8717 fix(audio): a sound is voice only with a voice-range pitch, judged on the whole clip (#6653)
* 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.
