Abstract
Real.-time musical effects processing and synthesis play a
part in nearly all musical sounds encountered in the contemporary
enviroflDlent. Virtually all recorded or electrically
amplified music in the last few decades uses effects processing,
such as artificial reverberation or dynamic compression,
and synthetic instrument sounds play an increasingly larger
part in the total musical spectrum. Furthermore, the vast
majority of these effects are presently implemented using
digital signal processing (DSP), mainly due to the flexibility
and low cost of modern digital devices. For live music, realtime
operation of these effec.:ts and synthesis algorithms is
obviously of paramount importance. However, also 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.
The purpose of this article is to provide the reader with
an overview of some of the recent advances in this fascinating
and commercially active topic. An exhaustive review of
all novel real-time musical effects processing and synthesis
would fiU a book. In fact, an earlier review on digital audio
effe·cts can be found in the book [ I] 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.
A tutorial on virtual analog oscillator algorithms, which arc
not tackled in this paper, has been written by Viilimaki
and Huovilainen [5] . Also, musical synthesis and effects
applications for mobile devices have been reported in [6]. In
order to conveniently fit in a single journal article, a selection
of some of the most active subtopics under this exciting
research field have been chosen for presentation here.
The organization of this review is as follows: adaptive
effects processing algorithms, such as the adaptive FM
technique, are reviewed in Section 2. Section 3 discusses the
emulation of vintage delay and reverberation effects, while
recent advances in tube amplifier emulation are studied
in Section 4. Real-time simulation of an interesting analog
effects device, the voltage-controlled filter, is reviewed in
Section 5, and recent advances in sound synthesis and
processing languages are discussed in Section 6. Finally,
Section 7 concludes the review.
