I'm using Audacity 1.3.12-beta on Mac OS X 10.6.7. In a band we recorded a couple of songs - in mono - and I converted them to mp3 files right away. And of course, I deleted the recordings immediately after converting. Problem is, now there's only sound in the left channel in the mp3's - how do I assign that to both channels?
Here's a picture to make things clearer:
Edit: before assigning the left track to both, I want to delete the right track, as it contains only noise.
