The configuration would drive a little module splicing together VPU or QPU kernels. I guess one approach would be to develop a web interface (over wifi) to the pi to wire and configure filters and load / save presets. My understanding is Andrew would have implemented FFT using internal Broadcom documentation as one of the news posts says he is a member of the Systems Group at Broadcom Cambridge.

I'm not sure about the hardware side of things (getting audio signal into and out of pi).īut in terms of access to DSP like accelerators (VPU and QPU), I think i've got a reasonable handle on developing that kind of code on the RPi (I've just uploaded a mini assembler for QPU at. I'm not into amateur radio or spectral analysis and I just picked up on the 'sound processing' part in the text, hence my post. IF it does then I know what'll get my attention for the next months to come (Yes I can build my own hardware but then I'd be alone and have no community to share/learn/progress with and I would have to spend many months before even getting something useful.)Ĭan someone who knows more about GPU_FFT and what I'm talking about please confirm, or deny, if this would work or not?

Hardware DSP solutions (Axe FX etc) costs mega money and the laptop ones rely on Windows - which is not exactly optimal if on stage and bluescreen flonks your guitar solo. If this is the case then I think we might have access to the holy grail in music equipment! I admit I haven't looked at the GPU_FFT yet and this is why I post this in order not to 'fool' myself into thinking something's possible if it's not, but with regards to the 'sound processing' statement in the GPU_FFT text I read - will this be powerful enough to finally turn the Raspberry Pi into a usable sound processor/emulator?

Ok, so we never got access to the DSP(s) in the Raspberry Pi which was mentioned as a 'maybe' by Liz in the beginning - and this I fully understand and can live with. (Yes, I admit that I actually use the laptop as playback device at 90% of my time instead of the expensive rig.) The last few years have been good to us musicians with regards to speaker emulation and digital effects and I can now easily match my Mesa Mark IV and Fractal Audio Axe FX 2 with just a laptop, Guitar Rig 5 and some tinkering with plugins and setup. Outside the world of computers I'm a pretty mean guitarist and I try to build my own rectifiers/amps and I've also played with FX. I still think Raspberry Pi is an excellent platform for tinkering and has so much more to offer than just a cheapo XBMC player or as an dedicated Amiga emulator (which was one of my early projects) or even as a central car computer with touch screen interface. I've been away from the raspi scene for quite a long while now but saw something that caught my eye this morning!
