Hi everybody,
Removing this code, would prevent any chance to somehow experiment with the HRTF processors of the vortex chips. It is the only persistent knowledge base of what is known about them. Deleting that code will erase that knowledge. I just want to make sure you know that.
Could you make patches to add some proper comments there?
thanks,
Takashi
Best regards, Manuel Jander
