This includes all [[sound]]s on the [[time scale (music)|time scale]] shorter than [[musical note]]s, the [[sound object]] time scale, and longer than the [[sample (signal)|sample]] time scale.  Specifically, this is shorter than one tenth of a [[second]] and longer than 10 [[millisecond]]s, which includes part of the audio [[frequency]] range (20{{nbsp}}Hz to 20{{nbsp}}kHz) as well as part of the [[infrasonic]] frequency range (below 20{{nbsp}}Hz, [[rhythm]]).<ref name="Roads">[[Curtis Roads|Roads, Curtis]] (2001).

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.<ref name="Roads"/>

Physicist [[Dennis Gabor]] was an important pioneer in microsound.<ref name="Roads"/> [[Micromontage]] is musical montage with microsound.

'''Microtime''' is the level of "sonic" or aural "[[syntax]]" or the "time-varying distribution of...[[timbre|spectral]] energy".<ref>[[Horacio Vaggione]], "Articulating Microtime", ''Computer Music Journal'', Vol.{{nbsp}}20, No.{{nbsp}}2.
