1. A method performed by one or more computers, comprising: receiving a reference vector including multiple reference audio descriptors for identifying audio content; receiving a query vector including multiple query audio descriptors of an audio snippet; identifying a match between the query vector and the reference vector, including determining a match probability between the query vector and the reference vector based at least in part on: a difference score of each query audio descriptor indicating a difference between the query audio descriptor and a reference audio descriptor ; and a conditional probability that when a query audio descriptor indicates that the query audio descriptor is interference, a subsequent query audio descriptor is also interference; and identifying that the audio snippet is a snippet of the audio content based on the match.
