Doppler

A stereo spatialization effect can be achieved using x,y coordinates to determine intensity and delay for the sound at each speaker at each moment. The hypothetical listener is placed at a point equidistant from the two speakers. The speakers are each assumed to be at some angle from the listener between 0 and pi radians, with 0 radians being straight to the right, pi/2 radians being directly in front of the listener, and pi radians being to the left.

For this example to work properly, you will also need to download the additional Max file "mix~.maxpat" from the example "A useful subpatch for mixing and balancing two sounds", which will be used as a mix~ object in this patch.
