Convention Paper

Non Linear Convolution and Its Application to Audio Effects

Authors: Tronchin, Lamberto

AES Convention 131 · Paper 8524 · October 2011

Abstract

The non linear convolution could be applied to enhance the linear convolution on acoustic musical instruments and audio devices. In this paper a novel technology, based on exponential sine sweeps measurements, is presented. The non linear convolution is based on the Volterra series approach and enables real time non linear emulation of acoustic devices (as valve amplifiers and musical instruments). The new developed tool (a VST plugin developed in C++ in JUCE framework) will be presented. The emulation of musical instruments will be compared with real recordings. The results will be finally analyzed and commented.
