I've been working with some folks who sell DAW plugins to port their synth & effects code to the Beagleboard and Beaglebone embedded computers. So far it appears to work pretty well - the Cortex A8 processor is sufficiently powerful to run the algorithms and the development environment is genera

Yes. It's just a matter of collecting the right linker scripts, startup code and compiler switches. Eric On Apr 13, 2012, at 1:45 AM, Victor Lazzarini wrote: > Could I use the same arm gcc I have it here installed for Android > cross-compilation, by any chance? > > Victor > On 13 Apr 2012, at

There R-Pi is incredibly cheap and has hdmi output. But... The analogue audio is a low quality 1 bit PWM, there is no DAC! You can't access the HDMI drivers, because of the licence agreement. There may be a possibility to use an external USB stick, if the device communicates fast enough with it, a

It is, in fact, an aliasing problem. I changed the code to use a sine table wich works fine. Then I implemented a phase distortion saw oscillator similar to the casio CZ series. when i increase the harmonic content (morph more and more to saw) I get the clicks again. But this is a special cas

Arduino paired with a decent ADC/DAC would be good just for lightweight DSP. It could be used to control a workhorse DSP through I2C communication, but I don't think there is any ready to go development board out there… you should wire it yourself, and program both the processors. alessandro On
