Would I be able to

1a. Receive an audio signal on Aux In, and convert it to a processable digital audio format (for short PDAF)

1b. Have one or more BT devices connected, and receive audio signals from there, then convert the signals to a PDAF

2. modify the PDAF (like shifting frequencies, adding or mixing signals, changing volume, do equalizing, etc etc). Can this be programmed in a common programming language, like C/C++/Java?

3a. convert the resulting digital signal back to analogue and output it to the phone jack 3b. output the resulting digital signal to a connect BT device (like speakers, headphones, etc)

4. How many concurrent BT connections (in/out) can be handled by this module?

Is this Lyra module needed for the tasks mentioned, or would the WROVER alone be able to do that?
