Other Plug-Ins : Other AudioSuite Plug-In Utilities : Normalize

Normalize
The Normalize plug-in optimizes the volume level of an audio selection. Use it on material recorded with too little amplitude, or on material whose volume levels are inconsistent (as in a poorly recorded narration).
Unlike compression and limiting, which modify the dynamics of audio material, normalization preserves dynamics by uniformly increasing (or decreasing) amplitude.
*
To prevent clipping during sample rate conversion, Normalize to no greater than the range between –2 dB to –0.5 dB. Optimum settings will vary with your program material and your Conversion Quality setting (in the Editing tab of the Preferences dialog).
 
Max Peak At
Specifies how close to maximum level (clipping threshold) the peak level of a selection is boosted. Set this value by adjusting the Max Peak At slider, by entering a numeric decibel value below the clipping threshold, or by entering a percentage of the clipping threshold.
You can normalize stereo pairs together so that two sides of a stereo signal are processed relative to each other.
RMS/Peak Toggle
Switches the calibration of normalizing between Peak or RMS modes. Peak mode normalizes the input signal at the maximum possible level without clipping. RMS mode normalizes the input signal at a level consistent with the RMS (Root-Mean-Square) value, or the effective average level of the selected clip.
Normalizing Multiple Clips Across Tracks
When multiple clips are selected across multiple tracks, the Normalize plug-in can search for peaks in two different modes:
Peak On Each Chan/Track
Searches for the peak level on a channel-by-channel or track-by-track basis.
Peak On All Chans/Tracks
Searches for the peak level of the entire selection. If ten tracks are selected, for example, the Normalize function will find the peak value from all ten.
To normalize an audio clip (or selection):
1 Select the clip you want to normalize.
2 Choose AudioSuite > Other > Normalize.
3 Adjust the Level slider as desired.
4 Ensure that Use In Playlist is enabled.
5 Click Render.
