We propose a new steganalysis approach against MP3Stego based on Huffman table distribution and recoding scheme. Huffman table distribution features are used to detect uneven quantization among blocks. Recoding scheme can be used to calibrate cover signals and to reduce the variety caused by different carriers. Experiments show that our method is successful in detecting MP3Stego even at a very low embedding rate.
