Mono to Stereo w/ Audacity...

September 2009

When you find yourself with a mono audio file and you need stereo, here is a way to change the file. First figure out if the file is a stereo file with only one track active or if is truly a mono track.

Open the file with Audacity. If you see two track but only one of the tracks have waveforms in it then you know its stereo. Use Audacity w/LAME or Quicktime Pro to convert the file completely to mono. Open the new mono file in Audacity.

Select all (Ctrl +A) (Cmd +A) Click Edit and Duplicate now you have two tracks showing and they are both mono.

On the left hand side of the track info it will show that the file is mono. Click the drop down button (up side down black triangle) Click make stereo track. Save. Export as WAV or MP3.

Make sure you have LAME and you know where its located on your system.
