Abstract—MP3 is the most widely used audio format nowadays in our daily life and music on the internet are often of this format. In order to seek commercial benefit, low bit rate MP3 audios are usually transcoded to high bit rate, resulting in fake-quality MP3 audios. Through analyzing the frequency statistics of Huffman table indexes, a method for detecting such fake-quality MP3 audios is presented in this paper. Experimental results show the effectiveness of the proposed method.
