What is a microphone preamp?
  • A device that provides electric current to the microphone to operate. (Good job!)
  • A device that samples the analog waveform from the microphone. (This is the converters definition.)
  • A device that changes the array of integers back into an analog signal. (This is the computer sound card's job.)
  • A device where the air molecules are spaced apart. (This is rarefaction.)
