Chromaprint is a C library for generating compact audio fingerprints, developed for the AcoustID music identification project. It includes the fpcalc command-line utility and is designed for identifying near-identical audio rather than general-purpose fingerprinting.
Use cases
- identify music tracks from audio files
- detect duplicate audio files in a library
- monitor long audio streams for known tracks
- generate AcoustID fingerprints for MusicBrainz tagging
- build a music recognition feature into an app
When to choose
- you need compact fingerprints for identifying near-identical audio
- you want AcoustID/MusicBrainz integration
- you need a fast C library with bindings in many languages
When to avoid
- you need robust fingerprinting against heavy distortion or re-encoding
- you need general-purpose audio similarity search rather than exact identification
