Abstract

This paper reviews some of the recent advances in real-time musical effects processing and synthesis. The main emphasis is on virtual analog modeling, specifically digital emulation of vintage delay and reverberation effects, tube amplifiers, and voltage-controlled filters. Additionally, adaptive effects algorithms and sound synthesis and processing languages are discussed.

Highlights

  • Real-time musical effects processing and synthesis play a part in most musical sounds encountered in the contemporary environment

  • An earlier review on digital audio effects can be found in the book [1] and in a recent book [2], while reviews of virtual analog modeling and digital sound synthesis can be found in articles [3] and [4], respectively

  • The convolutional section may be taken directly from the measured impulse response onset, and the equalization and decay rates of the feedback delay network (FDN) designed to match those of the measured late field response

Summary

Introduction

Real-time musical effects processing and synthesis play a part in most musical sounds encountered in the contemporary environment. Recorded music typically requires real-time operation of these devices and algorithms, because performers usually wish to hear the final, processed sound of their instrument while playing. An earlier review on digital audio effects can be found in the book [1] and in a recent book [2], while reviews of virtual analog modeling and digital sound synthesis can be found in articles [3] and [4], respectively.
