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.

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

Current analysis overview
When you run an analysis, similarity scores and timestamped evidence appear here for quick review.
Reference track
Sections: intro, verse, chorus, bridge. Structural labels used in alignment.
Uploaded track
Pitch tracks, chroma, and onset patterns are extracted for comparison.
Timestamped evidence
Segments where melodic, harmonic, rhythmic, or structural similarity exceeded your configured thresholds.
Explainability snapshot
Run an analysis to see a human-readable explanation of why tracks are considered similar, including transposition-invariant melodic matches, functional-harmony alignment, tempo-normalized rhythmic similarity, and structural overlap.
