USING ADOBE AUDITION
Effects reference
Measure input amplitude. Double-click the meters to reset peak and clip indicators.
Input Level meters
Measure amplitude reduction with red meters that extend from top (minimal reduction) to
Gain Reduction meters
bottom (maximum reduction).
Boosts or cuts amplitude after compression. Possible values range from -18 to +18 dB, where 0 is unity gain.
Gain
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
Ratio
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.
Determines how quickly compression is applied when audio exceeds the threshold. Possible values range from
Attack
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.
Determines how quickly compression stops after audio drops below the threshold. Possible values range from
Release
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.
Boosts or cuts overall output level after compression. Possible values range from -18 to +18 dB, where 0
Output Gain
is unity gain. Double-click the meters to reset peak and clip indicators.
Applies limiting after Output Gain, at the end of the signal path, optimizing overall levels. Specify Threshold,
Limiter
Attack, and Release settings that are less agressive than similar band-specific settings. Then specify a Margin setting to
determine the absolute ceiling relative to 0 dBFS.
To create extremely compressed audio, enable the Limiter, and then experiment with very high Output Gain settings.
Displays the frequency spectrum of the input signal, rather than the output signal, in the
Spectrum On Input
multiband graph. To quickly see the amount of compression applied to each band, toggle this option on and off.
Applies immediate, hard limiting at the current Margin setting. (Deselect this option to apply slower
Brickwall Limiter
soft limiting, which sounds less compressed but may exceed the Margin setting.)
Note: The maximum Attack time for brickwall limiting is 5 ms.
Lets you globally adjust the compression settings for all bands, while retaining relative differences
Link Band Controls
between bands.
To temporarily link band controls, hold down Alt+Shift (Windows) or Option+Shift (Mac OS). To reset a control in
all bands, hold down Ctrl+Alt+Shift (Windows) or Command+Option+Shift (Mac OS), and click the control.
