Granular synthesis is a sound synthesis method that operates on the microsound time scale. It is often based on the same principles as digital sampling but often includes analog technology. The samples are not used directly however, they are split in small pieces of around 1 to 50 ms (milliseconds) in length, or the synthesized sounds are very short. These small pieces are called grains. Multiple grains may be layered on top of each other all playing at different speed, phase and volume. Microsound includes all sounds on the time scale shorter than musical notes, the sound object time scale, and longer than the sample time scale. ...
A time scale specifies divisions of time. ...
Digital sampling, PCM sampling, or just sampling is the process of representing a signal waveform as a series of numbers which represent the measurement of the signals amplitude, taken at regular intervals. ...
An analog or analogue signal is any variable signal continuous in both time and amplitude. ...
Look up Phase in Wiktionary, the free dictionary Phase may refer to: Phase (matter), a physically distinctive form of a substance, such as the solid, liquid, and gaseous states of ordinary matter Phase (waves), the time position (or angle in the complex plane) within a cycle of a periodic waveform...
The result is no single tone, but a soundscape, often a cloud, that is subject to manipulation in a way unlike any natural sound and also unlike the sounds produced by most other synthesis techniques. By varying the waveform, envelope, duration, spatial position, and density of the grains many different sounds can be produced. A soundscape is an acoustic environment or an environment created by sound. ...
This article is about the musical concept of clouds. ...
Waveform quite literally means the shape and form of a signal, such as a wave moving across the surface of water, or the vibration of a plucked string. ...
The result is usable as music, sound effects or as raw material for further processing by other synthesis or DSP effects. The range of effects that can be produced include amplitude modulation, time stretching, stereo or multichannel scattering, random reordering, disintegration and morphing. Digital signal processing (DSP) is the study of signals in a digital representation and the processing methods of these signals. ...
Dennis Gabor researched how human beings communicate and hear. The result of his investigations was the theory of granular synthesis, although Greek composer Iannis Xenakis claims that he was actually the first inventor of this synthesis technique (Xenakis, Formalized Music, preface xiii). Dennis Gabor (Gábor Dénes) (5th June, 1900, Budapest - 9th February, 1979, London) was a Hungarian physicist who is most notable for inventing holography. ...
Iannis Xenakis Iannis Xenakis (Ιάννης Ξενάκης) (May 29, 1922 Brăila – February 4, 2001 Paris) was a Greek composer and architect who spent much of his life in Paris. ...
Curtis Roads is often credited as the first person to implement a digital granular synthesis engine. Canadian composer Barry Truax was one of first to implement real-time versions of this synthesis technique. Curtis Roads is a composer of electronic and electroacoustic music specializing in granular and pulsar synthesis, author, and computer programmer. ...
Barry Truax(1947-) is a Canadian composer who specializes in real-time implementations of granular synthesis, often of sampled sounds, and soundscapes. ...
