Abstract
A method is provided for monitoring audio content available over a network. According to the method, the network is searched for audio files, and audio identifying information is generated for each audio file that is found. It is determined whether the audio identifying information generated for each audio file matches audio identifying information in an audio content database. In one preferred embodiment, each audio file that is found is analyzed so as to generate the audio file information, which is an audio feature signature that is based on the content of the audio file. Also provided is a system for monitoring audio content available over a network.
