Just spotted this by accident on Google:

http://www.freedsp.cc

Looks promising. One of the main distinctions from MiniDSP as far as I can tell is that it has a GPIO board, meaning settings (like crossover frequency, bass boost or EQ bands) can be linked to potentiometers and buttons.

Definitely interesting, especially the open source bit
That can be a blessing or a curse, depending how clever you and other interested parties are

Last time I checked though a SigmaStudio license was around $250 though. That would be a stopping block if that is still the case.

Is that to get a license for commercial use or to use it at all? I can't find it for sale anywhere but it seems to be available for download here http://www.analog.com/en/dsp-software/ss_sigst_02/sw.html

Well I reckon it could potentially drop the price of DSP modules quite a bit. It is actually possible to build one, yet they charge us hundreds or more than a thousand quids to get our hands on basical and cheap hardware. Maybe DIY will be the way to go in the future like it has been for many things in the audio industry.

It looks like it may well go that way. It just takes a handful of dedicated people to realise when an industry has more or less plateaued, refine the best stuff into a few really good quality designs and spread and document them far and wide. Most end users only really need so many bells and whistles from a DSP. Top end professionals will always demand the best even if it's not strictly needed for the application so the market will be there, but the future's bright for DIY. Companies like Analog Devices just want to sell as many chips as they possibly can - I think a lot is probably going to all the start-ups making iPod docks and similar mass market consumer products, that's driving the prices down and the support and documentation up.

Audio is also a great gateway into learning to design all kinds of other things that use the same sort of skills.

That was to use it at all but as I said, they might have changed policy on that. It would certainly be very nice if they had because it's been a pain in the rear to custom program a DSP for the cAMP because of that policy.

i hope it works one day.
minidsp is nice, but control for it windows only (or maybe a mac too), no way to control it from a single board linux computer or a tablet. and they  stated on the forum that there is no way to change it :-(
