Mm well the kernel does it as far as I could tell by watching htop. I think the latently is mainly due to the Linaro image not being hard float ...

hey dan, do you have to tell pd to use it’s own core on udoo, or does it so automagically? has this something to do with the cpu group from your script (it did not exist on my system)

cheers

I don't know the latency. I can try testing that at let you know, but it's definitely good enough for what I need. It is at least lower than 20ms. Acceptable latency for guitar is 12ms, and I think I got around 16ms out of my old setup running on the Pentium III 500Mhz wearable.

The main deal with the UDOO, is that it's multiple cores (2 or 4 depending on the board you buy). This way, the kernel has a core, pd has a core, and there are 2 cores left over for other things (my HID-OSC device daemon, etc).

Hey Dan,

Looks like the UDOO is much better indeed from what you recently posted here. Could you tell us what latency you're achieving ? And which version you're using (with or w/o wifi) ?

Cheers,

Pierre.

Ok for small projects, but you're not going to interface a real stage mic or guitar easily. Would be much better if the next pi version comes with an onboard usb controller, which is the main problem for usb audio on the current pi. For now, the UDOO is where it's at for that.
