How do you invert audio in Logic Pro X so that your wave "peaks" turn into "dips" and your "dips" turn into "peaks"... basically flipping the audio upside down (should sound exactly the same when it is played). This was easy to do in Logic Pro 9 (you could just double click the audio and select "invert" in the audio editor).

No i'm not talking about phase inversion,

Yes, you are talking about Phase Inversion. This can be done with the Gain plugin. In the pic there's a Gain plugin on the top track; the bottom track is a bounce-in-place of the top track.

And maybe just to add that it can be done destructively to the audio file - same as in v9 - you just have to make sure you are in the FILE editor, and not the TRACK editor. And probably you have to enable the advanced thing.

You're quite right seeren, I never checked if it was indeed gone. so now Kim's got two ways of doing it...

I've never used Invert destructively, the only use I can imagine for it is to do null tests... but I would use the Gain plugin for that anyway...

Is this the way to do a "null test" in Logic? I am still using Logic Pro 9 and I am bouncing my mixes to Wave files but I want to make sure they sound exactly the same as my multi track Mixes...

Yes, using this feature (Inverting) of the Gain plugin is an essential ingredient of null testing. Also vital: aligning the two files sample-accurately.

If you want to compare two tracks for subtle differences using your ears (now there's a new concept), you could use a blind-testing app:

Thanks!

I had to turn on:

Preferences > Advanced >

✔︎ Show advanced tools

✔︎ Audio

and only then I manage to see the "Functions" drop down menu in the file editor.

Thanks guys!
