hi everyone!
I'm *very* out of my league here, but I'm curious...
I've been looking around at busybox, uClibc et al, and was wondering
if anyone has tried to build an "embedded" device that supports some
Linux audio software. For example, imagine taking a cheap/old pc,
equipping it with jack and a synthesizer of some sort (dssi?), and
taking it on a gig. It would need to be an "instant on/instant off"
device. I think this sort of project would be fun and would also be a
great use of old hardware, not to mention a real benefit for people
who gig regularly and need the random synth (and don't want to spend
the $ on hardware).
Of course, not being a programmer, there might be some major obvious
reason as to why it won't work that I'm not aware of. What do you all
think? Is this idea worth looking into?

I saw this one at LugRadio Live in San Francisco:

It has Ardour on it along with other stuff.

I'm very interested in this idea also. Currently I have one of my
colleagues working on getting Android onto our Arm platform.
Is there any specific issue that you are encountering?
Cheers.

Hi,
i'm planning to build my own guitar multieffects box, since i looked at all
the ones available and they all sucked, since there's no way to
customize/extend what's already packaged [well, they have some nice stuff in
there, but ultimately i want to experiment with, erm, unusual stuff]...
I searched and searched, looked at Blackfin, AVR, and other DSP/embedded stuff
and finally came to the conclusion that an Intel Atom board [mini - itx] with
a tight fit case (18x24x5cm) is what i want. I will need some extra hardware,
like an IO board for adding switches and swellers. I was thinking about using
an Arduino for this, especially as i still have one lying around here. Also i
need a way to get the guitar signal to line level, and back to guitar level. I
have a friend who's good with electronics, so he'll build a little preamp for
me. I don't need a harddisk. I think a 32Gig USB stick will be totally fine
which will get attached to one of the internal USB connectors.
My choice of program for creating the effects will be ingen, due to its nice
remote controllability via OSC (so i can write a little program or even just a
script that listens on the virtual serial ports representing the Arduino's IO
and fire off the nessecary OSC commands to ingen). But hey, it will be a
standard linux (though i guess i will compile a custom kernel withouth initrd
and all nessecary modules built in and a very stripped down selection of
sercices) so everything goes.
The CPU isn't nowhere as powerful as a modern desktop CPU, but it will be
enough for the experimental stuff i have in mind. It does have a fan though,
but whether that will be needed or not depends on the load on the system..
Regards,
Flo

Why did you dismiss Blackfin? There are quite a few audio tools for
it. At the last AES in SF, Digital Concepts demo'd Audio Weaver a
Matlab-based tool that comes with loads of modules. Seemed easy to
construct software and had about every module you might need. I think
it's free to download and use and then you pay when you release the
product to the market. More: http://dspconcepts.com/audio-weaver. Of
course, you'll need Matlab.
There's also VisualAudio from Analog Devices.
http://www.analog.com/en/embedded-processing-dsp/blackfin/content/visualaud…
(which I think is free)
Besides the proto boards from Analog, Danville Signal has some
interesting prototyping boards as well:

Free, but not open source again..

The main reasons for going for the atom board are
- Super easy packaging - I won't need to solder anything which i'm notoriously
bad at..
- Ability to use open source software exclusively (Linux, Ingen, LADSPA, DSSI,
LV2, SuperCollider) which i'm quite familiar with, which will save me loads of
time..
- It has an FPU [which you do not get on any DSP in the 70-Euro price range
(including board)..
- Cost: Total price will be around 250 euros, including the case, switches,
the Arduino IO, etc..

Flo
