MPEG-7 fingerprint (AudioID) based audio search utility

Within MPEG-7 descriptors for audio signals were developed, which belong to a certain piece of music comparable to a fingerprint.

A data base containing fingerprints of some thousands pieces of music can now be used to identify an unknown piece of music by generating a standardised fingerprint of 210 to 30 seconds of the unknown music and search for a match in the data base.

Within a database of 150000 pieces a reliable search can be done resulting in more than 99% correct hits.

The technology can be used for identifying of pieces music e.g. for media control applications.

Another application in the public domain are search and identification services to identify unknown hits of which some seconds have to be recorded and played to the search system. Contact to the search system was also demonstrated via mobile phones.
