(Not sure what you mean with resonance effect, reverb maybe?) The ADAU1701 is a self-contained device, and it cannot access resources available in external devices like the ESP32. It can be controlled by an external device, and it can send and receive data over I²S. The ESP32 and the ADAU1701 can be placed in series to process audio data. If your resonance effect can be split into several serial tasks, then you can do a part on the ESP32 and another part on the ADAU1701.
