Abstract
Systems and techniques for adding pitch shift resistance to an audio fingerprint are presented. In particular, an audio track for a media file is received. A first audio fingerprint for the audio track with a first pitch shift and an Nth audio fingerprint for the audio track with an Mth pitch shift are generated, where N is an integer greater than or equal to two and M is an integer greater than or equal to two. A combined audio fingerprint is generated from at least the first audio fingerprint and the Nth audio fingerprint.
