Espruino Wifi and SPW2430(microphone)

Thank you for clearing all that up! I really appreciate the fast response too, thank you for that. This is the first time im really trying to code something, im still very new to this. I had accidentally put analogWrite but I had meant to put analogRead, I thought I needed it because the signal is coming from the DC pin on mic into ADC of the espruino. When I run code you posted I get

  "System Volume Information",
  "X.raw"

I tried playing the new file changing proper parameters and Im getting static.
