Cycle-Frequency Wavelet Analysis of Electro-Acoustic Systems

Authors: Ponteggia, Daniele

AES Convention 143 · Paper 388 · October 2017

Abstract

A joint time-frequency analysis of the response of electro-acoustic systems has been long sought since the advent of PC based measurement systems. While there are several available tools to inspect the time-frequency response, when it comes to inspect resonant phenomena, there are always issues with time-frequency resolution. With a rather simple variable substitution in the Wavelet Analysis it is possible to switch one of the analysis axes from time to cycles. With this new cycle-frequency distribution it is then possible to analyze very easily resonances and decays. A PC based measurement tool capable of Cycle-Frequency analysis will be introduced.
