Teensy 4.0 + Audio Shield Guitar / Mic Mixer

Just found out about the teensy board and i would like to ask some questions to anyone that can help.
First post treat me gently :D
So i want to create a guitar / mic digital pedal and i would like to know if someone has tried something similar
and if it is actually possible.

Parts:
  1. Teensy 4.0
  2. Teensy 4 Audio Shield
  3. SparkFun THAT 1646 (Output)
  4. 2 x SparkFun THAT 1206 (Input)

The idea is to convert the guitar and microphone signals to unbalanced mono signals and
pass them as input to the stereo audio shield input.
I want to experiment with creating a digital guitar vocoder effect.

My questions are:

  1. Can i pass guitar + mic as 2 mono channels in the shield's stereo input?
  2. Can i split the stereo signal in the code to get both mono guitar and mic inputs at the same time?

Thanks a lot to anyone that can help!

Yes, stereo can be treated at 2 mono channels.

This 31 page tutorial might help.

If you turn to page 8, you'll see the design tool is used to create your audio processing. All stereo processing is done by drawing 2 mono paths. Hopefully you can see how the design tool lets you create pretty much any audio processing. There's absolutely no requirement to do the same thing to both left and right channels. You can draw anything you like in the design tool.
 
Thanks for your quick reply Paul, really appreciate your work.

This is enough for me to start exprerimenting,
if it turns up nice i will follow up.

Thanks again :D
