Research on Audio Fingerprinting Algorithm Based on Difference in Frequency and Time Domain

This paper is concerned with the analysis of audio fingerprint algorithm based on Fourier transform. In allusion to occurring problems of the existing algorithm in robustness, the authors modified the mode of energy division and difference between the sub-bands and presented an improved audio fingerprint algorithm which applied the difference in frequency and time domain. The proposed algorithm was analyzed subsequently, and experimental results showed that the proposed algorithms improved the robustness in several aspects such as low SNR and linear speed change than existing algorithm.
