I refered earlier to two European papers. Now I found this at
their site:

   Patents on sound rendering. We are in the process of filing for
   two US patents, together with N. Tsingos and E. Gallo on
   "Using graphics cards for audio signal processing" and
   "Perceptual techniques for sound spatialisation"

I'm sure the first patent is intended to cover all audio
processing in GPUs.

This is sad. Even if somebody has given a prior thought on that
GPUs could be used for audio processing, it does not help if all
these patents cover the only way to transfer and process audio in

The second patent deals with sound source clustering. I have
given a thought for that kind of clustering earlier than them
when I wrote GVerb. The number of early echoes are reduced by
grouping the virtual source points in 3D space and by representing
one group with one spatialized source point. They specially mention
the early echo reverberator as an application of their method.

When a person is killed, it means 8-14 years of prison: a life is
cheap compared to the intellectual property, which is worth of 20

So, I suggest I keep up with my intellectual property and we
implement our version of the invention. Your help is needed
in coding.
