Phylogeny analysis for MP3 and AAC coding transformations

The following paper presents our work on audio phylogeny with a focus on two application scenarios: audiovisual (A/V) archives and tampering detection. Starting from a set of near-duplicate audio files, our goal is to determine the processing history for the set, and detect the transformations that have been applied on each linked pair of nodes. Our approach targets AAC and MP3 encoding operations and is addressing both music and speech material.
