Separating Original Audio and Simultaneous Translation from a single audio file

Hello everyone!

I’m currently working on a project where I have a stereo audio file which is a simultaneous translation of an English original audio. It has two waveforms. One is in English (original) and the other is in Spanish. I’ve imported the file into Audacity and can clearly see the two waveforms since they are distinct, indicating the two languages. However, no matter what I try, I can’t seem to separate them effectively.

I’ve tried various techniques, such as splitting the stereo tracks into mono tracks and using the selection tool, but I haven’t had any success. Despite clearly seeing the two tracks on the screen, it seems like they’re “locked” together, and I can’t select or edit them separately.

Has anyone experienced something similar or have any suggestions on how I can approach this issue in Audacity? My goal is to separate the Spanish waveform from the English one so I can keep the Spanish waveform while removing the English one.

I really appreciate any help you can offer. Thank you in advance for your time and assistance!


There are playback “audio enhancements” which allow crossover between left & right.
That would allow a little of each channel to bleed onto the other one.

Having said that, if you split the stereo pair into two mono tracks, and mute one track,
you should only hear one language even with “audio enhancements” enabled.
