I've been away from the raspi scene for quite a long while now but saw something that caught my eye this morning!
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.
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.
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. (Yes, I admit that I actually use the laptop as playback device at 90% of my time instead of the expensive rig...)
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.
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?
If this is the case then I think we might have access to the holy grail in music equipment!
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...
(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...)
Can someone who knows more about GPU_FFT and what I'm talking about please confirm, or deny, if this would work or not?
IF it does then I know what'll get my attention for the next months to come
Many thanks in advance!
ps. 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.
