Besides a user-programmable DSP core, the ADAU1701 has high-quality analog-to-digital and digital-to-analog converters built-in and features an I²S port. This makes it suitable as a high-quality audio interface for the ESP32.\u003c\/p\u003e\n\u003cp\u003ePrograms for the ESP32 can be created with Arduino, Platform IO, CMake or by using the Espressif IDF in another way.
