==Etymology==
[[Latin]] transeunt-, transiens, present participle of transire to cross, pass by, from trans- + ire to go
*Date: [http://www.wikipedia.org/16th_Century 1599]
==Definitions==
*1 a : passing especially quickly into and out of [[existence]] : transitory <transient [[beauty]]>
:b : passing through or by a place with only a brief stay or [[sojourn]] <transient visitors>
*2 : affecting something or producing results beyond itself
==Synonyms==
transitory, ephemeral, momentary, fugitive, fleeting, evanescent mean lasting or staying only a short [[time]]. transient applies to what is actually short in its duration or stay <a hotel catering primarily to transient guests>. transitory applies to what is by its [[nature]] or [[essence]] bound to [[change]], pass, or come to an end <fame in the movies is transitory>. ephemeral implies striking brevity of life or duration <many slang [[words]] are ephemeral>.
==Description==
In [[acoustics]] and audio, a '''transient''' is a short-duration signal that [[represents]] a non-harmonic attack [[phase]] of a musical [[sound]] or spoken [[word]]. It contains a high [[degree]] of non-periodic components and a higher [[magnitude]] of high [[frequencies]] than the harmonic [[content]] of that sound. Transients do not directly depend on the [[frequency]] of the [[tone]] they initiate.
Transients are difficult to encode with many audio compression [[algorithms]], causing pre-echo.
A '''transient''' [[astronomical]] [[event]], often simply called in [[context]] by astronomers a transient, is an astronomical object or [[phenomenon]] which can be [[observed]] for a short period of [[time]]. Singularly, the term is used for [[violent]] [http://en.wikipedia.org/wiki/Deep_sky deep sky] [[events]] such as [http://en.wikipedia.org/wiki/Supernovae supernovae] and [http://en.wikipedia.org/wiki/Gamma_ray_bursts gamma ray bursts].
