Advantages of nonstationary Gabor transforms in beat tracking
- Andre Holzapfel, Gino Angelo Velasco, Nicki Holighaus, Monika Doerfler, Arthur Flexer
- In this paper the potential of using nonstationary Gabor
transform for beat tracking in music is examined. Nonstationary
Gabor transforms are a generalization of the shorttime
Fourier transform, which allow
exibility in choosing
the number of bins per octave, while retaining a perfect
inverse transform. In this paper, it is evaluated if these
properties can lead to an improved beat tracking in music
signals, thus presenting an approach that introduces recent
ndings in mathematics to music information retrieval. For
this, both nonstationary Gabor transforms and short-time
Fourier transform are integrated into a simple beat tracking
framework. Statistically signicant improvements are
observed on a large dataset, which motivates to integrate
the nonstationary Gabor transform into state of the art approaches
for beat tracking and tempo estimation.
