Transient (acoustics)

Add article description

In acoustics and audio, a transient is a high amplitude, short-duration sound at the beginning of a waveform that occurs in phenomena such as musical sounds, noises or speech.[1][2] Transients do not necessarily directly depend on the frequency of the tone they initiate. It contains a high degree of non-periodic components and a higher magnitude of high frequencies than the harmonic content of that sound.[3]

Transients are more difficult to encode with many audio compression algorithms, causing pre-echo.[4]
