i'm working on a 3D car sound engine using Granular Synthesis and VBAP-technique at the moment.

The only thing that is missing at the moment to make it sound more realistic is the doppler effect.

I've found the great doppler example patch in the Max-help files but it's only a one dimensional effect.

Has anybody heard of a 2d-doppler-tool or can give me any advices how to build it?

If it's of any use to see a Csound example, you can try:

Forgive the intrusion Christopher (and Benjamin); am I right in saying that you plan to convert this invaluable resource into pdf, or its own website, so that it's more readily accessible.

I'd really love to be able to browse (and use) these fundamental tutorial examples offline.

i dont see where the difference between a 1-dimensional and a 2- or 3-dimensional doppler could be.

the doppler effect itself is based on only one parameter: the distance between the sound source and the listener. and distance is always only one dimension in space.

that some natural sound sources are much broader than coming from only one point in space, and that the listener has two ears and not only one, are different issues.

for two sound sources and two ears you´d just use 4 channels of a "1-dimensional doppler". for a live recording containing a mix of different sources you have no chance recreating a natural doppler effect.
