How difficult would it be to extend it to 192kHz, or even 384kHz? Is it limited by the ESP32 hardware?
I'm using an STM32H7, not ESP32. The DAC on the PCM3168A can go up to 192 kHz, but the ADC can only be clocked up to 96 kHz.
For what application do you need 96kHz or 192kHz of bandwidth?
What ESP32?
