Questions tagged [audio-fingerprinting]

An audio fingerprint is a hash code of some digital audio, with the additional properties that it is tolerant of noise and distortion, and can be reproduced without synchronizing with the start of the audio. Audio fingerprints can be used to compare sampled audio with a library of known published audio.
