Hi, I just began working with Pure Data, and I want to make a multichannel audio player for 4 different signals (2 stereo wav playback files) but I needed it to be with xlr balanced outputs, standalone and can load files from an sd. I've researched and I've found that I need 4 dac on my embedded hardware, that is for each output signals, I've also found that the raspberry pi 2 is usefull for my project, because of its price and processing power, sd port and pure data support. But I can't find any board that has 4 dac or extention board that has them (any that works with) , can you recommend me a board that has them, works with pure data, low cost, can read files from an sd and could work as a stand alone unit?
Help! and thanks in advance!
