Default Teensy Audio Bridge for I2C/I2S lines


I'm working on a digital audio mixer for pro live mixing. I've been researching this for years but recently stumbled on the Teensy 3.6. It has a very nice library for creating an audio flow using a GUI and Arduino code. Check out the Teensy Audio Library here.

My first test was using the Audio Shield and it succeeded at proving that it is capable of doing what I needed, but the quality was pretty bad. So I purchased some cheap modules off ebay. They are a PCM5102A and a PCM1808. I successfully connected them to the Teensy. They worked great and the sound was much better.

Next, I plan on integrating some even better IC's for my project but before I do I was thinking about creating some type of audio bridge for the Teensy. This would make it easier for me to modularize my project and focus on the individual components rather than a full blown board. The plan is to hopefully get some community support. I've outlined the concept on my post about my project on the teensy forum. Check it out and let me know your thoughts. I'm seeking just an overall concept confirmation and maybe some advice on what features should and shouldn't be included on it.

Here is the link to my project and some more information about this potential bridge.
