Hi Rodolfo,
but all happens is that they play together now…
Perfect! For now.
On the first of the two, I applied the `invert’ effect.
Are you sure?
Where’s the comparison…?
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… …Maik Waschfeld
