This landmark-based audio fingerprinting system is able to match short, noisy snippets to a reference database in near-constant time.

This is my implementation of the music audio matching algorithm developed by Avery Wang for the Shazam service. Shazam can identify apparently any commercial music track from a short snippet recorded via your cell phone in a noisy bar. I don't have the database to check if my version is quite that good, but it is able to rapidly match and locate a poor-quality excerpt from within a database of (at least) hundreds of tracks.

See http://labrosa.ee.columbia.edu/~dpwe/resources/matlab/fingerprint/ for the "published" output of the demo script.

Versione Pubblicato Note della release
1.2.0.0

Fixed a problem where problems would occur if query contained audio before matching reference item (i.e. negative match time offset). Improved robustness (at cost of matching speed) by dithering time framing of query.
1.1.0.0

No change to code, but added link to notes for running on Windows.
