Re: [chuck-users] PI Chucking contest...

Oh, I should add that this is all running at 44.1kHz. Joel On 12/05/2013 11:23 AM, Joel Matthys wrote:

OK, this is not any kind of official benchmarking, but here's a rough performance estimate of ChucK on the Raspberry Pi:

Setup: Raspberry Pi Model B, no overclock, running Raspbian, 3.6.11+ USB sound card (little PnP device, <$10) No monitor or keyboard; logged in via ssh

Testing multiple oscillators: Up to 10 simultaneous SinOsc: no problem 10-12 mild glitching

Testing multiple shreds: Using OTF examples, 6 shreds at once, no problem 7 shreds, major gapping

Testing LiSa: LiSa-munger1 example works for up to 24 voices at once!

------------------- Overclocking should improve performance. I expect that unplugging the ethernet cable and auto-running a patch would help too.

Overall, I'm pretty impressed with its capabilities!

Yes, it compiles and runs nicely on the Pi. I'll try a little performance test and get back to you shortly!

I've run into this problem too while compiling ChucK for the Raspberry Pi.

I admit: In the back of my mind, I still view the Raspberry PI as a very capable embedded controller. So I'm happily agog at what it's really capable of.

Do you have ChucK running on the RPI? And if so, what's a rough assessment of its performance, e.g. how many voices can it synthesize?
