Upload audio for analysis

MP3, WAV, FLAC. Multiple files, up to 500MB each. We'll run a fingerprint pre-check then deep similarity analysis on promising matches.

Drag & drop audio here or click to choose files

We create deterministic fingerprints for fast candidate search, then run melodic, harmonic, rhythmic, and structural comparison.
