#85305 I'm working on a project where I need to record voice(about 5 to 10 seconds) using pre-amplifier connected to A0 pin of esp8266 (NodeMCU). I found the library and code for arduino https://github.com/TMRh20/TMRpcm/blob/master/examples/xtraFeatures/Recording/Recording.ino but how this is possible with esp8266. I'm getting 10 bit resolution samples to A0 pin, is there any way that I can store those values and encode those values to pcm or mu-law file. I'm new to audio processing please help.

Thank you.
