In an audio pass-through test using Pd, with a USB sound card (Griffin iMic), the maximum stereo sample rate before ‘breakup’ is 32000.In mono, it sounds \u201cok\u201d at 44100. Latency seems low enough to use for music but I’m too sleepy to figure out the numbers.<\/p>\n
<\/div>\n
I don\u2019t know enough about Linux audio to say if the performance deficit is due to ALSA drivers, the sound card, background processes, pd, the CPU, or what?Anyway I ‘m guessing R-Pi will spawn interesting synths and lo-fi FX processors. They\u2019re cheap enough you could use them in parallel.<\/p>\n
Prediction: They’ll double the speed, and sell a million more by the end of the year. We\u2019ll see a range of \u2018Pi\u2019 clones which run the same Linux distributions, but offer various speeds and IO options. It feels like the democratization of manufacturing has taken another huge leap.<\/p>\n
