Abstract

This talk introduces a causal approach to tempo tracking for musical audio signals. The tempo tracking system is divided into two sections: an onset analysis stage, used to derive a rhythmically meaningful representation from the input audio, followed by a beat matching algorithm using auto- and cross-correlative methods to generate short term predictions of future beats in the audio.
