DIY Guitar Effect Processor using Orange Pi PC plus, Armbian and Guitarix
Posted: Wed Sep 21, 2016 7:53 am
I've always loved the idea of making a DIY effect processor.
Currently I'm making a fully analog one (which is kind of offtopic in this place.. ) and a digital one (now we're talking...).
I've bought a Orange Pi PC Plus (OPi) for under 20 euro's, installed Armbian on it and build Guitarix from source.
After adding myself to the audio group, tweaking the audio priorities and killing Pulseaudio, I'm able to get a <10ms latency with my usb soundcard.
Although there is some streamlining to be done, the concept works.
Final goal is to install a small touchscreen on top of the OPi and replace the bulky usb soundcard by a small diy soundcard, with the whole shebang mounted in a stombox.
I've found the following breakout board for the TLV320AIC audio codec chip . Although soldering digital IC's is new for me, I worry the most about getting the codec to talk with my PI, but we'll cross that bridge when we get there.
I would love to get some advice to further fine tune the setup (what processes can be shut down?).

p.s. for further reading: I've got some assistance so far over at the Guitarix and Armbian forum.
