I have scoured forum and many other chips and cannot find a single solution that can answer the following question.
I need to be able to..
1) Take an analog input
2) Take I2S input
3) Mix analog + I2S inside chip
4) Output I2S
All of the above needs to happen systematically and with minimal/no delay.
I have found plenty of chips that can analog in and I2S in, but none of them state whether or not they can output I2S in/out at the same time.
Imagine a scenario where you have person doing commentary over the top of a movie while the end result is going to a switching chip. (Actually we are using the ADV7625 in this scenario).
Is there a way to implement what I am doing with one chip? Two Chips? Or what do I need to do to make something like this work?
