Description: This program will operate in 3 main modes:
Normalize - it will find the highest amplitude in a pcm-wav file, and then amplify the wav file so as to give it the maximum possible amplitude.
NOTE: the % normalization is % of maximum volume - 100% - max volume (default)
Find Peaks - scans the file for the higest amplitude, and reports the highest and lowest level found, and also a gain which would give the file maximum amplitude if it were amplified by that gain.
Amplify by x - this allows the wave file to be amplified by a given value (which can be less than 1) to increase or decrease the volume.
