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.

Abstract: This disclosure relates to transformation invariant media matching. A fingerprinting component can generate a transformation invariant identifier for media content by adaptively encoding the relative ordering of interest points in media content. The interest points can be grouped into subsets, and stretch invariant descriptors can be generated for the subsets based on ratios of coordinates of interest points included in the subsets. The stretch invariant descriptors can be aggregated into a transformation invariant identifier. An identification component compares the identifier against a set of identifiers for known media content, and the media content can be matched or identified as a function of the comparison.

Abstract: Implementations are provided herein relating to audio matching. A variable length local sensitivity hash (“LSH”) index can be created through a careful examination of existing LSH bands in the LSH index. LSH bands with offset lists that meet a band size threshold can be lengthened repeatedly until a maximum length threshold is reached or an offset list associated with a lengthened LSH band fails to meet the band size threshold. The LSH index can be further tuned by down-sampling or discarding LSH bands that reach a maximum length threshold and still lack discriminate properties.
