Transferring Sound From Left to Right Speaker

I have an audio clip that has all of its sound on the left speaker and none on the right, and I was wondering how to copy some of it over to the right. Couldn’t find the answer to this anywhere online

You can do that with the “Channel Mixer” plug-in https://forum.audacityteam.org/t/channel-mixer/14632/1

Alternatively, if ALL of the sound is on the left speaker, then (with Audacity 1.3.x) you can click on the track name and select “Split Stereo to mono” and then delete the silent track.
