Browse Source

- 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/
