TLDR
An improved audio fingerprinting extraction algorithm which was proposed by Shazam company is proposed, which uses a combinatorial hashed time-frequency analysis of the audio, yielding unusual properties in which multiple tracks mixed together may each be identified.Abstract:
Audio fingerprinting, like human fingerprint, identifies audio clips from a large number of databases successfully, even when the audio signals are slightly or seriously distorted. In the paper, based on 2-D, we propose an improved audio fingerprinting extraction algorithm which was proposed by Shazam company. The algorithm uses a combinatorial hashed time-frequency analysis of the audio, yielding unusual properties in which multiple tracks mixed together may each be identified. The results of experiment verify the improvement in the retrieval speed and accuracy.read more

A novel audio fingerprinting method robust to time scale modification and pitch shifting
TL;DR: A novel audio fingerprinting method that is highly robust to Time Scale Modification (TSM) and pitch shifting is proposed, based on computer-vision techniques that transforms each 1-D audio signal into a 2-D image and treats TSM and pitch shift of the audio signal as stretch and translation of the corresponding image.
