Hello all, I want to start making a standalone 8 channel player (maybe more) - something that can be used in museums, festivals etc for sound installations that can just be turned on and will instantly start looping a multichannel composition on an sd card. At the moment I am using rather unwieldly setups of small computers and multi channel soundcards such as RME and motu. Cables can easily be jogged loose and it would be nice to have something more robust and that staff can easily just turn on and off. So I have looked into the arduino (only 12 bit audio) and the raspberry pi but neither seem suitable . Systems already avaailable are ludicrously expensive (1000s of euros) Has anyone got any ideas on the best way to go about this - is there something maybe Im missing with the raspberry pi/ arduino that could be customised ? Perhaps a custom made circuit board ? Ideas ? best, Gus
i was thinking of looking into a raspberry pi combined with a usb 1.1 class compliant audio device such as the ESI Gigaport HD+. that's less than 200 euros in hardware for eight channels of output. the only downside to this setup is that the outputs are unbalanced rca. if necessary, two 4way DI boxes can be added at reasonable extra cost, but then those will be 10 times the size of the actual player unit...
