It's my expectation that the internal A/D of the ESP8266 isn't up to the job of audio sampling.

This project writeup - ESP8266-based baby monitor - describes how to use external A/D that passes the data to the ESP8266 via I2S. Lots of other useful audio info in there as well

[link fixed, thanks guys]
