Removing static from one mono channel of a stereo recording

Post by EmilyCCO » Mon Jun 12, 2017 9:49 pm

Hi all,

I'm editing a podcast recording that I made on an Zoom H4N. I've had issues with static appearing on ONE of the channels of the stereo recording. Relatively new to Audacity, and I don't know if I can remove static on just one mono channel without affecting the other channel. Related to this - if it is possible to edit or delete audio from one channel, can I copy and paste the good audio from the other channel to make it sound like stereo again? Thanks for your help. I've attached a screen shot so you can see what I'm dealing with.

It looks to me like data corruption. Possibly due to the flash media failing?

The left channel shows severe damage, so I think the best thing you can do is to delete that channel and use the (good) right channel as a mono recording. A mono track will play through both speakers.

From the track dropdown menu, select "Split Stereo to Mono", then delete the bad track by clicking on the [X] in the top left corner.
