I am attempting to use a joystick to control sound using VBAP. However, my joystick maps from 0-255, and I was wondering if there is a way to make this easily correlate to degrees on the azimuth/elevation.

I would like the controller to read out “0″ when forward, “90″ when panned right, and so on.

Thanks for any help you can give!

For azimuth/*distance* (2d panning) you need to (probably) scale and offset the x and y values and convert to polar coordinates and change the radians to degrees – see cartopol

If you *are* actually attempting to control azimuth/*elevation* (suggesting 3d panning) I’m not sure how the elevation would intutitviely map to a joystick alone (joystick in centre is up, at perimeter is down?) But that will be a bit more involved to obtain. as you would need to convert the resultant 2d distance value of the distance/angle pair to specify elevation

The scale function did help with the values, and now I am looking into the cartopol function, and messing with the parameters. Thanks so much for your insight!
