spike(rust/fixtures): extract audio fixtures and compute JS baseline offset - #101
Merged
Conversation
…offset Closes #94. Two 8 kHz mono s16le WAV fixtures (300 s each, ~4.6 MB each) extracted from the raw episode files using the exact ffmpeg params AudioSyncer.js uses internally. JS baseline computed by running AudioSyncer.computeCrossCorrelation → findBestLag → validatePeak against the fixture WAVs directly; lagSeconds: -6.8 s, SNR: 9.8, isReliable: true. Sources: video-audio.wav ← input/video/IMG_5240.MOV (raw camera audio, stereo→mono) audio-track.wav ← input/audio/AiBubble.wav Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
