Hello,

i am successfully using the HiFiBerry DAC+ and a Raspberry Pi for a synthesizer project which is a live-coding collaborative spectral synthesizer, visuals are generated by a GLSL script and fed to the Raspberry Pi through the network, the RPI is used as a raw additive synthesizer with up to ~700 simultaneously playing pure tones oscillators at the moment, the DAC+ is used to output the result to my fx processor/equipments.

Here is some videos :

This setup was done in a single week and i plan to do a bit more with the RPI and DAC+! :)

  Hi,

  this look pretty cool. Is there any guide or How-to document? It might be interesting for other users.

  Best regards,

  Hello,

  there is no guides nor documents at the moment, the complete software documentation is in progress and will be available soon though, the hardware setup is pretty simple, it is mostly all softwares basically but i am looking to make some more "heavier" hardware experiments with the DAC+ and RPI.

  This setup was done because the visuals of this synthesizer (the score part) need to be generated by a computer with a beefy GPU, the client which produce the visuals is browser-based, it does not run on the RPI and web audio performances on the client side is rather shoddy so i needed a little something which would sit next to me which would just get all the data from the client and output quality audio optimally without interruptions that i could send to any other equipments, the RPI and HiFiBerry DAC+ is perfect for this and it work like a charm!

  The software sources are available here :
