Are you sure?

That’s what you hear!
If you play two exact files „in sync“, and one of them is inverted, you should hear … nothing.

Try with two instances of the same file, not one wav-mp3-wav and the other one wav.

The process in detail:
- select one file in the Finder
- right click and „Open with“ Audacity
- select the imported file in Audacity; be sure, that the hole file is selected and stays selected for the next step!
- >Effects>Inverted (my version is german, so it could be named otherwise in english)
- >Import>Sound and select the exact same file, you used on „Open with“
- Play.
- If you hear nothing, then the process is correct. If you hear anything but silence, then one of your steps was not correct.
- If you select „Solo“ on one of the tracks, the other track gets muted and you can toggle between „the difference“ and the „Solo-ed track.

With kindest regards…
