Hiya -
These are the e-mail replies that I received that have to do with
people who actually are using the DSP in different projects:

Well i'm working with a prof at the U here (University of Calgary)
doing speech synthesis with the DSP.
They (we) are writing a TextToSpeech object. I am writing an
animation tool, the user will enter a line of text, the computer will
display an animated talking face on the screen and will also say what
you typed in.
Hows that for interesting

Dear 'jiro',
I read you letter on comp.dsp and wondered if you had posted it to
comp.sys.next. You'll probably be snowed under with replies.
Here at the University of Hull (UK), in the Comms Group, Dept. Electr. Eng.,
we have just taken delivery of a few NeXTs which we will be using to attempt to
port across some of the research going on here:
In particular -
pseudo-noise using Trajectory derived sequences
modems
matched-filter detection systems
fractal noise comms systems
If you want any more info, eg paper refs just give me a buzz
The NeXT will be the staple for the investigation into Radio Systems
architecture and more of the machines will be ordered.
As for the DSPApp Kit you talked about, there is a need for such a
system, but you can use the LSI HyperSignal Program on the PC to generate
code. However, if you are a DSP-jockey, you will realise that most code
is `hand-crafted' for real-time speed. So combining this with the NeXT
will hopefully produce some really excellent research (and demos).
Cheers,

Subject: NeXT DSP
I had hoped to write FORTRAN preprocessor that would
inspect loops for vectorization, replace those vectorizable
with appropriate library calls (and optionally produce a
loop-analysis listing), and invoke the compiler. The DSP
hardware would be used by those library calls at run time.
But the 56000 is integer-only. I wish NeXT had used
the 96000 in their latest machines since that chip has
floating point support.
A similar preprocessor could have been used for C.
NeXTime.
----------
Hope this helps people. Please send replies on your projects to
comp.sys.next and comp.dsp, I'd really like to sponsor a discussion on the net
about different uses of the DSP.
What is the Shaman Group doing? We're currently investigating its uses
as a general purpose image processor, trying to use it for some special
effects, etc.

Hiya - Here are another person using the DSP. I think it'd be great if there was a general directory of DSP related projects, kinda like what NeXT On Campus has for campus projects. Of course, someone would have to set it up and maintain it.... Talking about speech processing [bad pun intended], I wish there were a public domain speaker-dependent speech processing module. Something real simple but usable to a certain limit. I'm sure all of us have apps that could use *some* simple speech interpreting (like "send", "deliver", "display", "calculate", etc.). Another realm for the DSP is in data input. I'm going to be hooking up a powerglove Real Soon Now. But the only library I have that does it (PowerGlove, on cs.orst.edu) doesn't have the source code, which makes me uncomfortable. Anyone have a publicly available version? --------------- From: Bo Eriksson <boe@kuling.docs.uu.se> Organization: Teknikum, Uppsala University, Sweden Just reporting for a friend who doesn't read USENET news; he (lk@ctrl.teknikum.uu.se, Erlendur Karlsson) is planning to use the NeXT DSP chip for (real-time) speech processing. Would be interesting to see any whacky & weird things people plan to do with a DSP!
