Abstract: A system and method of determining if copyrighted audio material is being performed or broadcast within an establishment. One or more audio monitoring units are placed within the establishment. The audio monitoring unit detects audio signals inside the establishment and converts those signals into a corresponding data. Server software is provided that receives the data via a communications network. The server software compares the data to at least one database of copyrighted material looking for segment matches. The server software analyzes the segment matches to determine if the duration and/or nature of any segment match warrants the payment of a royalty. One or more performing rights organizations are sent a report detailing performances within an establishment so proper royalties can be distributed to the appropriate songwriters.
