Microsound includes all sounds on the time scale shorter than musical notes, the sound object time scale, and longer than the sample time scale. Specifically this is shorter than than one tenth of a second and longer than 10 milliseconds, including the audio frequency range (20 Hz to 20 kHz) and the infrasonic frequency range (below 20 Hz, rhythm). (Roads 2001, p.vii and 20-28) A schematic representation of auditory signaling Sound is vibration, as perceived by the sense of hearing. ... A time scale specifies divisions of time. ... This article is about music. ... In general, a sample is a part of the total, such as one individual or a set of individuals from a population (of people or things), a small piece or amount of something larger, a number of function values of a function, or part of a song. ... This article is about the unit of time. ... A millisecond is an SI-derived unit of time, equal to one thousandth of a second. ... Sine waves of various frequencies; the lower waves have higher frequencies than those above. ... Infrasound is sound with a frequency too low to be detected by the human ear (less than approximately 20 hertz). ... Rhythm (Greek ρυθμός = tempo) is the variation of the duration of sounds or other events over time. ...

These sounds include transient audio phenomena and are known in acoustics and signal processing by various names including sound particles, acoustic quantum, sonal atom, grain, glisson, grainlet, trainlet, microarc, wavelet, chirplet, FOF, time-frequency atom, pulsar, impulse, toneburst, tone pip, acoustic pixel, and others. In the frequency domain they may be named kernel, logon, and frame, among others. (ibid) Acoustics is a branch of physics and is the study of sound, mechanical waves in gases, liquids, and solids. ... Signal processing is the processing, amplification and interpretation of signals. ...

Physicist Dennis Gabor is an important pioneer in microsound. (ibid) Micromontage is musical montage with microsound. Dennis Gabor (Gábor Dénes) (5th June, 1900, Budapest - 9th February, 1979, London) was a Hungarian physicist who is most notable for inventing holography. ... Musical montage (literally putting together) is a technique where sound objects or compositions are created from collage. ...
