RX-7 audio v2: turbo whistle + exhaust from the action-cam library

CI / quality (push) Successful in 1m4s

Details

- Scanned b-action-cam-footage/clipchamp (99GB, 5 videos of the FD):
  extracted audio NAS-side via linuxserver/ffmpeg container (stream-copy),
  scanned 69min return drive per-second for engine tonality + whistle
  prominence (1.5-9kHz peak vs band median)
- New rev loop: 985-993s highway pull — 0.0Hz pitch drift over 8s,
  whistle ~1.7kHz at +33dB, exhaust + turbo captured together (seam 0.001)
- New whistle-only loop: same pull high-passed 1.2kHz — isolated spool
- SoundController: optional per-car Whistle layer that rides boost
  (throttle held at speed): fades in past 25% speed, pitch 0.9->1.35
- ROTARY_SOUND.md updated; three .ogg uploads needed in Studio now

RX-7 rotary loops: extracted from the owner's real car footage

CI / quality (push) Successful in 49s

Details

- Sourced from c-finished-videos/2026-07-10 sessions (the actual FD)
- Scanned 6 min of audio per-second for RMS/dominant-freq/spectral
  flatness; picked the most tonally-stable stretches (idle: 272-288s
  @ ~99Hz flatness<0.02; rev: 319.5-327s @ ~105Hz, louder)
- Zero-crossing trim + 150ms equal-power tail-to-head crossfade =
  seamless loops (seam jump 0.001 / 0.005); normalized to -3dBFS
- Shipped as assets/audio/rx7_idle_loop.ogg + rx7_rev_loop.ogg (236KB);
  wav masters mirrored to NAS 001-1993 Mazda RX-7/sound/
- ROTARY_SOUND.md updated: only Studio upload + 2 asset IDs remain

Sound: two-layer engine architecture + rotary pipeline for the RX-7

CI / quality (push) Successful in 43s

Details

- SoundController rebuilt around idle+rev loop crossfading (real racing
  game approach): idle layer barely pitch-shifts (keeps engine character),
  rev layer carries the speed range; crossfade window 5%-45% of top speed
- Per-car CAR_SOUNDS table so the RX-7 gets real 13B rotary loops while
  other cars keep the generic set
- docs/ROTARY_SOUND.md: full record->loop->upload pipeline for capturing
  the owner's REAL RX-7 (extract audio from video, zero-crossing cut +
  equal-power crossfade seam, normalize, ogg, Studio upload, wire IDs)
- Toolbox rotary rips evaluated and rejected: unauditionabe off-platform,
  short/unloopable, murky rights; the real car beats any rip
