If anyone is interested in the result of inverting audio files, below is a =
demo.

The first 20 seconds are the correct audio. 20 - 25 seconds is with the ori=
ginal wav file inverted (hence no output). 25 - 30 is back to the origiinal=
 audio. 30 seconds to the end is with and MP3 version of the file inverted.

What you hear in the last part of the file is the audio that hasn't been ca=
ncelled out by inverting the phase. In other words, audio that was left out=
 of the MP3 conversion.

Ironically, in order to upload the file, the final format is MP3.
