Hi all,
For one of the projects I am working on I need to connect to two computers via USB, one for input, one for output. I'd like to transfer the signal between the two Teensys digitally to avoid noise. Currently I have a Teensy 3.2 as the input, and a Teensy 4.0 as the output. I'd like to stick with the 3.2 on the input for now, though I should probably do some experimentation to see if changing makes more sense.
SPDIF seems like a good choice, since in theory I can transfer the required two channels of audio rather easily. However, I'm also using the audio board on the input Teensy, which means I need SPDIF and I2S at the same time. I know that normally this isn't possible. On another thread long ago (I can't seem to find it again, my search skills are failing me) someone (Paul I vaguely recall) mentioned that it would be possible to modify the audio library such that it would allow both SPDIF and I2S on the 3.2.
So...am I remembering this correctly? And if I am, has anyone attempted this, or has any pointers on how to accomplish this?
Thank you!
