Hello, I am at a very interesting place where I cannot find ANY documentation on any forum for the following scenario.
I am trying to create a circuit that can take in multiple inputs, including Analog + I2S, and I am trying to mix them internally on a DSP, and then I want to output the result on BOTH an I2S and Line Level out at the same time. Essentially no lag.
Typical Scenario Analogy: Imagine a professor playing a video in a classroom. They have a microphone and want to talk over the microphone while the movie is playing to make commentary.
I have stumbled upon Texas Instruments PCM3070 and it appears to be able to do the job.. until you read section 2.5.5 Secondary I2S which states "This multiplexing capability allows the PCM3070 to communicate with two separate devices with independent I2S/PCM busses, one at a time."
I am willing to switch to another chip if someone points me to one that is proven to be capable of doing this. But the PCM3070 looks so good and I want to believe that it is able to perform the above task.
