Sound Data Transmit from Arduino to PC

[pinkybri]

Hello everyone, I'm a total newbie and I need help with my project. I'm trying to build an Arduino-based digital stethoscope and it has to be wireless. I'm using MAX4466 and thinking to use ESP8266 for wifi communication. As far as I've done, MAX4466 is working and I can see data on serial port but by a cable input to PC.  However, I cannot figure out how to use ESP8266 for transmitting sound data, that have taken from MAX4466, to PC. What can I do about it? Since I'm pretty unfamiliar with those kinds of electronics topics, your suggestions are very important for me, thanks in advance.

Or if you have any other suggestions for transmitting data (it can be bluetooth maybe other than wifi), I would like to get any help.

The ESP8622 ADC is only 10bit, and it has a limited sample rate. If you want to capture decent quality audio you'll want to use an I2S (not to be confused with I2C) ADC. A better solution would be to use an I2S microphone module directly, like the INMP441.

ESP32 has I2S.  It also has Arduino library support.
