I am totally new to usb audio. i have read a lot of threads. i also found the design tool.
it seems what i want is not possible with teensy 4.1. I want to make 2 usb midi I/O . that is no problem since i already tested more of them.
But i also want 2 or 4 stereo audio outputs. And all need to work at the same time.
i do not need inputs nor fancy things. just an usb audio device with 2 or 4 stereo outputs.
The channel concept is not clear to me either. so either in would need 4 audio objects with stereo output. or 1 audio device with 4 independent stereo outputs.
I get that i need multiple i2s.
would this be possible? or is that using too much processor power and memory?
i would imagine that standard chips would exist that offer this.
the audio i need is 16 bit 44khz.
I hope some expert can tell me. the fact that it does not exist yet probably means it is not possible but since in am new i want to be sure before i give up this route.
