I will try to generate audio files.  They need to be in DVD audio or CDA
format as they require SurroundSound which doesn't fit into MP3.  I'll do
what I can but, once the software is rewritten, it will be smaller and
easier to use than simply downloading a huge audio file.

When I wrote "seconds" I meant it.  Of course, these are simple geometric
primitives in wireframe form so the complexity of something as real as a
basketball with its nubbies and stripes could break my model.

I'll get you guys something as soon as I can.  My next project is AutoCAD
for blinks <laugh>.

Chris, you are amazing, you write faster than I can read! <g>
Thanks for responding so quickly. I did not actually ask for
software though, but just audio samples to get a real "feel"
for what you described in your interesting blog entry. Of
course you may have restrictions in offering audio samples as
well, I don't know, but I'm sure lots of people would like to
know how "intuitive" your audio rendering of geometric shapes
will sound. I'll readily admit that "seeing with sound" using
The vOICe is not at all easy to master - a weak point for
which I have no solution in store. If your audio renderings
are intuitive as well as general in their capability to deal
with arbitrary 3D shapes and/or visual images, that would be
a breakthrough.

I was particularly intrigued by you writing

Thus it would seem most effective and convincing if you could
put these existing audio samples online?

Best wishes,
