High-Selectivity Filter Banks for Spectral Analysis of Music Signals

Abstract

This paper approaches, under a unified framework, several algorithms for the spectral analysis of musical signals. Such algorithms include the fast Fourier transform (FFT), the fast filter bank (FFB), the constant-Q transform (CQT), and the bounded-Q transform (BQT), previously known from the associated literature. Two new methods are then introduced… (More)
