Rhythm analysis
Introduction
Rhythm analysis consists of technologies that automatically parse the rhythm content of a music signal, and extract high level meaningful rhythm characteristics. The signal is firstly analysed in multiple frequency bands and the evolution of multiple features per time are processed to extract the relevant rhythm periodicities of the music signal. These are then further processed to extract high level semantics, such as the tempo, the time signature and the beat positions. The proposed methods achieves comparative results to the Sate-of-the-Art for a variety of music genres.
