Envelope options
Envelope graph Depicts time along the horizontal ruler (x-axis) and the new output level along the vertical ruler
(y-axis), with the blue line representing amplitude change.
Amplification Specifies where the top of the graph is, measured in percentage. When you draw an envelope curve,
the top of the graph is whatever percentage you specify and the bottom is 0%. The default value of 100% means no
change in volume occurs.
Use the Envelope effect to make tones generated with Adobe Audition sound more realistic.
Hard Limiting VST effect
Like the similar process effect, the Amplitude And Compression > Hard Limiting VST effect drastically attenuates
audio that rises above a specified threshold. However, you can combine the VST version with other effects in the
Mastering Rack and Effects Rack. In Multitrack View, you can also vary the effect over time by using automation
lanes. (See “Automating track settings” on page 204.)

Hard Limiting VST options
Limit Max Amplitude To Sets the maximum sample amplitude allowed.
To avoid clipping when working with 16-bit audio, set this value to no more than -0.1 dB. If you set it to -0.5 dB,
you’ll have a little more clearance for any future edits.
Boost Input By Preamplifies audio before you limit it, making a selection louder without clipping it. As you increase

commercials.
Lookahead Time Sets the amount of time (in milliseconds) generally needed to attenuate the audio before the
loudest peak is hit.
Note: Make sure that the value is at least 5 milliseconds. If this value is too small, audible distortion effects may occur.
Release Time Sets the time (in milliseconds) needed for the attenuation to rebound back 12 dB (or roughly the time
needed for audio to resume normal volume if an extremely loud peak is encountered). In general, a setting of around
100 (the default) works well and preserves very low bass frequencies.
Note: If this value is too large, audio may remain very quiet and not resume normal levels for a while.
Link Left And Right Links the loudness of both channels together, preserving the stereo image.
