Have you ever found yourself in a situation that you desperately want to know how to split stereo audio file into two separate Mono left and right channels in REAPER ? You are not alone. I once ran into such situation once in the past, when a client sent me a podcast to edit. It was an interview session. Apparently, he recorded the audio in stereo, whereby he recorded himself on the left and the interviewed guest on the right. Image attached below. I had to split the channels into two so I can manipulate them separately for seamless editing. The problem was, I couldn’t figure out how best to do this.
It occurred to me there should be a way to get this done, and the first intuitive idea that hit me was to duplicate the audio in two separate tracks, then pan one 100 percent left and the other 100 percent right. Well, that seemed to work to an extent, but for the fact that a tiny bit of the audio from the other side was still slightly audible. Then I thought to myself, this is the awesome REAPER, there’s got to be a faster and easier option to do this tucked away somewhere in the DAW. Hence, I hit the user manual. Alas! I was right, Reaper hardly disappoints. I found the one click option to get this done.
How to split stereo audio file into two separate Mono left and right channels in REAPER:
- select the audio item you want to split and right click on it
- Scroll to item processing
- Locate and click the option that says “Explode multichannel audio or MIDI items to new one-channel items”
Now your audio gets separated into different mono channels. By default, these two channels are routed under a folder. You can go ahead and un-group them, if that’s what you want. Now, you can seamlessly manipulate the audio individually independent of each other. Hope you found this useful.
