I want to interace he analog sensor with ESp8266 vesion 7 or Version 12.however My questiones are
1) what kind of ADC ESp8266 verison7/12 uses?
2) what will be sampling rate for which ADC performes from analog sensor?
3)how to configure it.CAN we configure using ARDUino IDE?
4) How to transmit the ADC data via WIfi(i mean what palteform to be used)?

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]
