The audio waveforms are fine in the Fairlight tab, but after splitting my stereo track in to two monos, they both show the same in the edit tab


You can see in the pictures I've added here, anyone know a fix to this? It's just annoying when cutting details.

There are differences between the tracks which I have highlighted. The waveform suggests that there is very little stereo content in the track.

This is one of my stereo files split into 2 mono tracks viewed on the Edit page.

To show a more marked difference, here is an M/S track split into two mono tracks on the Edit page.


Right click on the clip in the Media Pool. Select Clip Attributes.
In the Audio tab change the Format to Mono, Tracks to 2, and click Add. You should see the result as per the pic. If you don't want the stereo track click on the bin symbol next to it. Now when you import the clip it will have 2 mono audio tracks.

Hey thanks for the help! I know there are slight differences but when I solo the top track, the loud waveform parts are quiet (which they should be) so the waveform is still wrong.

I can't change it in the Media pool as it's one audio file for both tracks, since it was a Stereo that had been split and if I right click it in the actual timeline then the part you said to change is greyed out

Okay I did what you said actually and I can use that next time, but I'm still confused as to why now the waveform is clearly showing wrong? When it's right in the Fairlight tab, shouldn't it cross over and display correctly in both?

Is this a bug, or something...

I have to actually click and change the waveforms to mono, in the edit tab, even though I've already done it in the fairlight tab? It makes sense for it to just be in sync rather than having to do it twice
