I don't think Teensy is a viable platform for this. For digital audio mixer, one of the most important factors is latency and this is where Teensy solution falls apart.
More reasonable approach would be to use something like XMOS chip to handle the streaming and FPGA for signal processing.
That being said, it's still looking like a fun project.
- chabad360 3y agoYea, maybe (although I'm not able to quickly find what the teensy DSP's latency looks like), for the same price you can complain that its pre-amps are gonna suck. But on the other hand, this is much easier to implement and work with (and be cheaper) than most/any fpga systems.
- MartijnBraam 3y agoThe Behringer X-air mixer does everything realtime with a lot of processing for 18 channels on a bog standard 400Mhz arm core, no special hardware needed.
- varispeed 3y agoAccording to this: https://vogelchr.blogspot.com/2015/11/behringer-x-air-xr18-teardown.html https://vogelchr.blogspot.com/2015/11/behringer-x-air-xr18-t... It utilises XMOS and FPGA and 400MHz ARM is only to handle the user interface.
- MartijnBraam 3y agoThe fpga probably only does routing, it certainly can't handle effects
