Audio Fingerprinting
A technique that compresses an audio signal into a compact digital signature, enabling track identification by extracting spectral feature points. It is robust to noise and encoding distortion.
Timeline (last 90 days)
Audio fingerprinting compresses an audio signal into a compact digital signature, extracting from the frequency spectrum feature points that are robust to noise and encoding distortion, and identifies tracks by comparing against fingerprints in a database.
The limitation of audio fingerprinting lies in database coverage: for unregistered live recordings, private releases or non-commercial tracks, fingerprint matching may fail, in which case tools usually need to fall back to conventional metadata search.
