I need to write a report on the elements of recording and processing sound. I have looked on many websites and i cannot find the technical process of recording and playing back sound. (from microphone to speaker) If you have any idea or know of a website that can tell me i would be very grateful

The Howstuffworks web site explains how sound waves are converted to electrical current fluctuations through a microphone and back to sound through a speaker. Go to:
