Dejavu: audio fingerprinting and recognition in Python

(6 votes, average: 3.17 out of 5)

Audio fingerprinting and recognition algorithm implemented in Python, see the explanation here: How it works Dejavu can memorize audio by listening to it once and fingerprinting it. Then by playing a song and recording microphone input, Dejavu attempts to match the audio against the fingerprints held in the database, returning the song being played. Note that for voice recognition, Dejavu is not the right tool! Dejavu excels at recognition of exact signals with reasonable amounts of noise. Installation and Dependencies: Read INSTALLATION.md Setup First, install the above dependencies. Second, you’ll need to create a MySQL database where Dejavu can store fingerprints. […]
