Normalization
the audio volume is low and you want to increase the volume of the entire recording. You can
normalize the entire audio file (if no audio is selected) or a specific selected section. By default,
the current selection is normalized to 100%. If no audio is selected, the current selection is
becomes the entire presentation. When Normalize is selected, the best volume is chosen based
on the peak volume of the selection. The setting of 100% is relative to the best volume for
the selection.
When Normalization is not selected, 100% is relative to the original volume of the selection.

variations in the volume of the recording. This selection is helpful if there are frequent and
noticeable variations in the loudness of the speaker's voice. The default settings for Dynamics

amplification that will be used in the Dynamics option. The default, 2.0, means that the
quietest sections will be amplified by a factor of 2. Higher settings are useful in presentations
that have larger differences between quiet and loud sections. However, background noise can
also be amplified with higher settings.
The Noise Threshold option helps control the amplification of background noise. Anything
quieter than the noise threshold will not be amplified. If background noise is being amplified
too much, turning this slider up may help. However, the Dynamics option does not work well
with high noise levels.
Whenever you change these settings, the view in the Edit Audio dialog box is updated, so you
can see the results of your changes before clicking OK.
