I have limited experience converting .wav stereo files to .wav mono files. So perhaps a solution exists in Wavelab that I’m not finding?
If nothing similar exists I am wondering if the below is something that could be incorporated as a feature in a future Wavelab version?
Conversion is easily done with batch processing. But I am wondering about the visual where you can see the stereo vs. mono parts in a single .wav.
