Merge left and right audio tracks into a stereo file with sox on Linux.

by

I have a few audio files that are split into left and right audio tracks. I needed to merge them into stereo files, and I have found out how to do this.

The sox sound utility for Linux can perform this task admirably. Here I have a music file and I am merging the left and right tracks into one audio file very easily.

This is a very simple task.

Another way is to use Audacity and mix the two tracks together.

In the above example, I have moved the stereo slider left for the left track, and right for the right track.

Then, go to File -> Export and export as an ogg file, or whichever format you want.

This is also a nice way to do it, if you do not want to use the command line.
