I finally was able to do some function on an audio file with my program. I was able to reverse a stereo audio WAV file and play it backwards. The next 2 pics show the file loaded in Audacity.
With this confidence builder, I feel equipped to create a C++ class, WavFile that will extract various parametric information from WAV headers, and also perform functions on the audio data to create new WAV files.
At this point with a clear vision of what must be done for audio WAV file manipulation, all that is left is C++ implementation of the WavFile class.
