Ok guys, got some awesome news. Nvidia just released RTX voice, an AI noise suppression algorithm, I have just tested it on the Order 66 scene from ROTS and was able to remove the music. Trying to fiddle with it to see if I can keep SFX in place a bit better.
There are rumors that this can run on non RTX hardware, ; ) the net is your friend. Apparently it used CUDA and Nvidia just artificially locked it to RTX only GPUs.
