Normalize To Highest Peak Level & User Adjust
Select NORMALIZE (Constant Audio Gain) from the File\Effects Menu\Pop-Up Highest Peak
Figure 1: Selecting this function creates (without any dialogue from BBPro) the application of a constant amount of gain to an
the audio recording displayed in the waveform window to bring the average or peak amplitude to a peak target level.
There are no adjustments available on this selection, as the software will simply increase the gain of the displayed audio file
to the maximum (self directed to the level of first peak in the file to hit maximum)
NOTE: There is no Undo function, so if you wish to reverse the normalization done by simple selection, click on
[Cancel & Exit] Open the file again to add processing as desired.
Select NORMALIZE (Constant Audio Gain) from the File\Effects Menu\Pop-Up To Target Level (User Adjustable)
Figure 2: Selecting this function creates (with user adjustment) the application of a constant amount of gain to an
the audio recording displayed in the waveform window to bring the average or peak amplitude to a peak target level.
Proceed to Figure 3.

Best to experiment and look at the waveform post normalization. Specific adjustments require users to view and listen to the changed file after its normalized.
[Remove DC Offset] DC offset is usually undesirable when it causes clipping or undesired distortion other undesirable change in the operating point of an amplifier.
Wikipedia writes: In audio recording, a DC offset is an undesirable characteristic of a recording sound. It occurs in the capturing of sound, before
it reaches the recorder, and is normally caused by defective or low-quality equipment. The offset causes the center of the recording waveform to not be at 0,
but at a higher or lower value, for example, +1 or -1. This can cause two main problems.
a) Either the loudest parts of the signal will be clipped prematurely, since the base of the waveform has been moved up, or
b) inaudible low-frequency distortion will occur.
Low-frequency distortion may not be audible in the initial recording, but if the waveform is resampled to a compressed or lossy digital format, such as an MP3,
those corruptions may become audible
Experiment with the [Remove DC Offset] activate button and let the sound of your audio file make the final decision if its needed or not.
