1. An apparatus for fingerprinting an audio waveform, comprising:
- a memory that stores a codebook comprising one or more multivariate vectors, each multivariate vector comprising one or more spectral features and represents a corresponding one of a plurality of codes; and
a processor configured to divide the audio waveform into a plurality of bins, compute one or more spectral features for each bin, and generate a fingerprint representing the audio waveform with a string of codes from the codebook based on the computed one or more spectral features for each bin.

Abstract
A method and system for analyzing audio files is provided. Plural audio file feature vector values based on an audio file'"'"'s content are determined and the audio file feature vectors are stored in a database that also stores other pre-computed audio file features. The process determines if the audio files feature vectors match the stored audio file vectors. The process also associates a plurality of known attributes to the audio file.
