<div text="#000000" bgcolor="#FFFFFF" class=""><p class="">I'm a little late to the party on this thread. I have a
considerable number of hours invested in evaluating Audio Weaver
and I'll offer a review of Audio Weaver here.</p><p class="">The good stuff:</p><p class="">Audio Weaver is a highly developed visual design tool for audio
processing. If you have some knowledge of real time digital audio
techniques, using Audio Weaver should be very familiar to you. I
bought the $50 STM32F726 Discovery board for my work and it works
with Audio Weaver with no problems.<br class="">
</p><p class="">The audio processing chain is wired visually using a mostly
intuitive UI that has the familiar selectable block palette on the
left and the design workspace on the right. There is a native
emulation mode which allows the designer to run and test the
design on Windows. The design is then easily switched to a target
board by flipping a software switch. Switching is seamless
although switching to the target brings with it the possibility
that you'll run out of compute power. There is a handy realtime
CPU loading meter on the design server that is relevant when
running on the target.<br class="">
</p><p class="">There is a reasonable and capable Audio Weaver design interface
API that allows target application code to control the design in
ways that seems to have no limits. They call it "integration".
All parameters of all blocks are adjustable in real time. I'll
even speculate that an entire processing design can be wired at
run time. I never tried that.<br class="">
</p><p class="">Licensing the ST version is free but must be licensed annually.
There are at least several block processing packages that can be
used. The basic core module package is free and provides basic
modules, and there are many. The advanced core module package
costs $1k annually and has many nice modules. For what I presume
is a lot more licensing cost, one can obtain advanced tools to
write custom modules. I found myself lusting for that capability
but have no source of funds to justify it.</p><p class="">The bad stuff:</p><p class="">The documentation does not match the product that I evaluated
including the scant Getting Started guide and that was a real
frustration. I followed my gut in the getting started process and
eventually everything worked as expected. Help is available via
forums on the DSP Concepts web site. The forums are monitored by
vendor experts and question turnaround time was typically a day or
two in my experience. I never asked hard questions and the
answers I received were usually accurate.</p><p class="">I found the basic module package to be too basic for me. The
advanced package has many nice advanced blocks that, in theory,
one could make up for the lack of rich modules in the basic
package to concoct. It would be simpler just to spend the advance
package $1k licensing cost than labor through the work. DSP
Concepts states "most users" won't need the advanced package. I
identified my need after a week of poking at it. I doubt my
programming experiments are more advanced than most users so I
think DSP Concepts got that wrong.</p><p class="">You're on your own if you can't get a BSP for your DSP board.
The BSP is probably easy to do though, of course, depending on
your physical design.<br class="">
</p><p class="">Summary:</p><p class="">DSP Concepts has an excellent product in Audio Weaver. The
product works well and the learning curve is short. Documentation
is tragically deficient. You'll need quite a bit of money to
become fully provisioned to realize the tool's full capability.
The free complement is fun to learn but not enough capability for
my needs. I plan to continue to use the free Audio Weaver for my
hobbyist use but I would not recommend being armed only with the
free complement before starting a professional project.</p><p class="">John Speth<br class="">

<div class="">Hey all,<br class="">
<br class="">
So if someone were to totally lose their mind and go
down the road of implementing an IR reverb on a stand
alone processor, which would be a good choice? I don't
think floating point is needed, is it? Obviously you
need lots of cycles per sample and a fair bit of memory
(6 seconds * 48K rate * 2 buffers = >1MB).<br class="">
<br class="">
I looked at the Blackfins, they seem to be a good fit.
What else? It would be nice to start with an evaluation
board. Not too expensive software tools is also a plus.<br class="">
<br class="">
Extra credit question: will this get me committed? ;-)<br class="">
