- Video audio is captured as it plays, so a 20-second clip takes at least 20 seconds to process.
Field notes
The page sets a 100 MB and 120-second ceiling, and notes that the browser must support the file’s codec. Its pitch tracker targets fundamentals from about 65–1,000 Hz (C2–B5); the site warns that chords, drums, overlapping parts, effects, and noise can confuse results. Video audio is captured during playback, so processing cannot finish faster than the clip plays.
