Measurement of Audio Equipment with Log-Swept Sine Chirps

Authors: Kite, Thomas

AES Convention 117 · Paper 6269 · October 2004

Abstract

The log-swept sine chirp provides a way to measure the transfer function and harmonic distortion of an audio device simultaneously. A deconvolution operation separates the linear and non-linear responses in time. Results on real audio equipment are compared to classical methods and found to agree. An extension for simultaneously measuring crosstalk is suggested.
