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 one tenth of a second and longer than 10 milliseconds, which includes part of the audio frequency range (20 Hz to 20 kHz) as well as part of the infrasonic frequency range (below 20 Hz, rhythm).
These sounds include transient audio phenomena and are known in acoustics and signal processing by various names including sound particles, quantum acoustics, 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.
