This
archive includes a Matlab implementation of a tool allowing to
detect whether an MP3 file has been previously encoded with a
lower quality and, if this is the case, also estimates the
previous bitrate. As such, this tool is a candidate solution
for the fake quality detection problem. The tool is described
in T. Bianchi, A. De Rosa, M. Fontani, G. Rocciolo, and A.
Piva, "Detection and classication of double compressed MP3
audio tracks", Proceedings of 1st ACM Intl. Workshop on
Information Hiding and Multimedia Security,Montpellier, France
June 2013. A demo program and a sample dataset are included.
