Normalize
The Normalize plug-in optimizes the volume
level of an audio selection. Use it on material re-
corded 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.
Max Peak At Specifies how close to maximum
level (clipping threshold) the peak level of a se-
lection is boosted. Set this value by adjusting the
Max Peak At slider, by entering a numeric deci-
bel value below the clipping threshold, or by en-
tering a percentage of the clipping threshold.
You can normalize stereo pairs together so that
two sides of a stereo signal are processed rela-
tive to each other.
RMS/Peak Toggle Switches the calibration of
normalizing between Peak or RMS modes. Peak
mode normalizes the input signal at the maxi-
mum 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 se-
lected, 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.
To prevent clipping during sample rate con-
version, Normalize to no greater than the
range between –2 dB to –0.5 dB. Optimum
settings will vary with your program mate-
rial and your Conversion Quality setting (in
the Editing tab of the Preferences dialog).
