attack transient : The actual attack waveform. See transient.

transient : A non-periodic sound waveform or electrical signal. Any of the non-sustaining, non-periodic frequency components of a sound, usually of brief duration and higher amplitude than the sustaining components and contribute most to a soundís timbre. Transients usually occur near the onset of the sound such as the attacks of musical instruments, percussive sound, or speech consonants, which are called attack transients.

transient distortion : This includes transient intermodulation distortion (TIM). The beginning and ending transients of musical sounds are largely what determine their timbre, rather than their harmonic content. An audio device which passes steady-state signals perfectly well may distort the loud, high-frequency transients, causing audible coloration of the music. Low transient distortion means a device must have a wide, linear frequency response, no phase distortion, and no hangover. TIM is caused by amplifier slew-limiting and is principally a problem in solid-state amplifiers that use large amounts of negative feedback.

transient generator : See envelope generator.

transient response : (1) The instantaneous change in an electronic circuitís output response when input circuit conditions suddenly change from one steady-state condition to another. (2) Accurate transient response is the reproduction of sound such that high-frequency and low-frequency sounds reach the listenerís ear at the same time. See time alignment.
