I have never dealt with digital audio interface like I2S.
I want to use ESP-07S / ESP8266 audio interfaces as digital audio I/O (for mic + speaker). ESP-07 has two I2S interfaces: 3-wire audio input interface and 3-wire audio output interface.
I found the IC WM8974 of Cirrus Logic a bit interesting. Here is the recommended schematic/interface shown at the last pages of its datasheet:
Datasheet of WM8974: https://d3uzseaevmutz1.cloudfront.net/pubs/proDatasheet/WM8974_v4.7.pdf
The names of the signals of them are different. For example, there is no "MCLK" signal on ESP-07. I wonder if it is possible to interface that audio IC with the ESP-07... If yes, how do I need to interconnect the parts?
If not, which kind of IC should I use to interface to that ESP-07 I2S interface? This audio IC is called "audio coded mono", so for what keywords should I search.
This is shown on the ESP-07 manual about its I2S:
