Audio fingerprinting techniques aim at successfully performing content-based audio identification even when the audio signals are slightly or seriously distorted. And the fingerprint extraction algorithm is a great important part of this system. In this paper, we present a new feature extraction algorithm, which is based on the Discrete Cosine Transform (DCT) and Audio Spectrum Flatness (ASF). The ASF is a feature of the MPEG-7 standard, which are new to the audio feature family and have not been considered as much as other feature types. DCT is applied to the sub-band ASF of each frame for it has a strong...
