MONO VS. STEREO SOUND

Summarize the key differences between stereo and mono? Why is each important? If I were recording an interview with someone in a noisy environment, which might be a better type of microphone to use: stereo or mono? Why?

   Stereophonic sound is the copy of sound when using more than 2 independent audio channels creating the feeling of sound heard from many different directions. It's much more expensive than Mono and is used for film, television, music players, and FM radio.

   Monaural (monophonic)has audio in a single channel, often centered in the “sound field”. i.e. and stereo (Stereophonic) are classification of sound.
