Wave field synthesis (WFS) is a spatial audio rendering technique, characterized by creation of virtual acoustic environments. It produces artificial wavefronts synthesized by a large number of individually driven loudspeakers from elementary waves. Such wavefronts seem to originate from a virtual starting point, the virtual sound source.
The technology your PC uses to make sound is usually based on replaying an audio sample. Brian Heywood looks at alternatives., PC Pro; Stefan Bilbao (2009). Numerical Sound Synthesis: Finite Difference Schemes and Simulation in Musical Acoustics. John Wiley and Sons. pp. 11– 14. ISBN 978-0-470-51046-9. Lutz Trautmann; Rudolf Rabenstein (2003).
This phenomenon can be observed near sound emitters, or in the standing waves within a Kundt's tube. Acoustic streaming was explained first by Lord Rayleigh in 1884. [1] It is the less-known opposite of sound generation by a flow. There are two situations where sound is absorbed in its medium of propagation:
However, a cylinder closed at both ends can also be used to create or visualize sound waves, as in a Rubens Tube. The resonance properties of a cylinder may be understood by considering the behavior of a sound wave in air. Sound travels as a longitudinal compression wave, causing air molecules to move back and forth along the direction of travel.
A programmable sound generator (PSG) is a sound chip that generates (or synthesizes) audio wave signals built from one or more basic waveforms, and often some kind of noise. PSGs use a relatively simple method of creating sound compared to other methods such as frequency modulation synthesis or pulse-code modulation. [1]
Additive synthesis more broadly may mean sound synthesis techniques that sum simple elements to create more complex timbres, even when the elements are not sine waves. [ 7 ] [ 8 ] For example, F. Richard Moore listed additive synthesis as one of the "four basic categories" of sound synthesis alongside subtractive synthesis , nonlinear synthesis ...
