Simon,
Would you be interested in developing an audio output 3D function for high performance CW reception?

Pseudo stereo?
I have this already but could be improved.

Pseudo stereo could be a starting point. The idea is to locate any signal in the given passband somewhere in the space, the center of the filter will be the center of the virtual space.

An interesting paper.
Play with Pseudo Stereo - Ribbon Bar, Receive, Mode, Pseudo Stereo.

I did it already, that's way I said it is a starting point.

Probably a good project for 2021.

It is going to be implemented in SDR#.
