Testing audio for copyright infringement

When suspecting copyright infringement, the key is to be able to access the source of the infringement, with a precise point of origin within the plagiarised track, for exact comparison. Where recordings have been plagiarised but slightly altered by stretching or modifying the sound quality, the match may not be immediately obvious to the naked ear and one may have to trawl through hundreds of recordings looking for clues.

TEST

Tests were conducted with the well-documented case of Joyce Hatto (already tested by MC in the original AudioDB CHARM case study; further research published in IEEE) The interface gives the possibility for immediate sampling and comparison of segments of audio identified as being similar, or in some cases identical, from their exact point of origin. A continuous feedback loop enables further sampling and refining of infringement claims.
