ABSTRACT:
A system, method, and computer program product retrieve information associated with the signals. The information retrieval can be performed on a signal by quantizing the signal, forming words, and indexing based on weights of the words. The words are formed by grouping letters together to form a number of words within predetermined threshold values. The weights of the words are determined using a binomial log likelihood ratio analysis. The present invention may be applied to identification of an unknown song.
