AES Convention 147 · Paper 552 · October 2019

Abstract

This work introduces a new type of test signal called Modulated Musical Multitone (MMM): sinusoidal tones outlining E-minor triads in several octaves with amplitude modulation providing a variable crest factor which can match specific musical signals. Three different signals are used in the corresponding experiments including MMM, sinusoidal sweep, and music. An evaluation of sound quality is conducted for an FIR-filtered single horn driver. The effect of masking is observed when a matching linear low-pass channel is added to the signal. The multitone response is post-processed to obtain the distortion products spectrum.
