Re: [PD] [OT] Raspberry Pi Wolfson Audio Card
While I'm sure that Dan is right that the UDOO is the better choice for USB audio, I do have to say that I've had decent success using my Raspberry Pi as a guitar effects processor, with the Behringer UCG102 interface. There's definitely a lot of quirkiness to getting it running... for example ALSA gets in an infinite restart loop when attempting low latency on pd-extended, but vanilla starts up fine under the same settings. And then there's the fact that an issue in the kernel screws up USB audio on major distros like Raspbian. I'm using the Satellite CCRMA distro right now with much better success. So far I've got various delays, a looper, and a waveshaper distortion running within the same patch, at 20ms latency with very few noticeable dropouts. Parameters are adjustable with a QuNeo MIDI controller and with a button attached to the GPIO pins. The Pi is a bit more affordable than the UDOO boards, but then again I had to buy a powered USB hub.

Parameters are adjustable with a QuNeo MIDI controller and with a button attached to the GPIO pins. The Pi is a bit more affordable than the UDOO boards, but then again I had to buy a powered USB hub. Ultimately for one audio input the Raspberry Pi could probably serve most purposes, while the UDOO is more likely to scale to bigger installations. ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list -- Rafael Vega email.r...@gmail.com ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

Re: [PD] [OT] Raspberry Pi Wolfson Audio Card
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.
