I don’t think I understand this correctly. It’s just feeding a microphone into an amplifier, isn’t it? Why is there a computer in this at all?

- thedanbob 3y ago> This board [WM8960] was more suited for this project than my previous choice, the TPA2016D2. ... However, I now needed a microcontroller to initialize and control the WM8960. I chose the $10 ESP32 because it would allow me to operate the WM8960 and also accept audio via a Bluetooth connection from, say, my phone, and stream it to the WM8960.
