ADOBE AUDITION 3.0
User Guide
122
Ratio Sets a compression ratio between 1-to-1 and 30-to-1. For example, a setting of 3.0 outputs 1 dB for every 3 dB
increase above the compression threshold. Typical settings range from 2.0 to 5.0; higher settings produce the
extremely compressed sound often heard in pop music.
Attack Determines how quickly compression is applied when audio exceeds the threshold. Possible values range
from 0 to 500 milliseconds. The default, 10 milliseconds, works well for a wide range of audio. Faster settings may
work better for audio with fast transients, but such settings sound unnatural for less percussive audio.
Release Determines how quickly compression stops after audio drops below the threshold. Possible values range
from 0 to 5000 milliseconds. The default, 100 milliseconds, works well for a wide range of audio. Try faster settings
for audio with fast transients, and slower settings for less percussive audio.
Delay and echo effects
About delays and echoes
Delays are separate copies of an original signal that reoccur within milliseconds of each other. Echoes are sounds that
are delayed far enough in time so that you hear each as a distinct copy of the original sound. When reverb or chorus
might muddy the mix, both delays and echoes are a great way to add ambience to a track.
To access familiar options from hardware delays, use the Echo effect in Adobe Audition.

Analog Delay effect
The Delay And Echo > Analog Delay effect simulates the sonic warmth of vintage hardware delay units. Unique
options apply characteristic distortion and adjust the stereo spread. To create discrete echoes, specify delay times of
35 milliseconds or more; to create more subtle effects, specify shorter times.

Analog Delay options
Mode Specifies the type of hardware emulation, determining equalization and distortion characteristics. Tape and
Tube reflect the sonic character of vintage delay units, while Analog reflects later electronic delay lines.
Dry Out Determines the level of original, unprocessed audio.
Wet Out Determines the level of delayed, processed audio.
Delay Specifies the delay length in milliseconds.
