This has been suggested for Bandicam already, but it would be more suitable for Bandicut.
Please add the ability to convert a mono track to stereo.
This also applies for stereo tracks that only use one channel.
Maybe you could even add the ability to control how much of the track is played in the left channel and how much in the right to simulate position of the audio relative to the listener.
Even this can be done in 3D-space.
This was the last one.
Have a nice time and best regards,
