Part 1. What's the Difference between Stereo and Mono?

What is mono sound?

Up until in the 1940s, sound recordings were in mono. Monophonic or monaural sound is recorded using a single microphone and is opened using a single loudspeaker. If you want to listen to mono sounds using multiple speakers and headphones, the paths should be merged into one signal before transmission. In this case, the signal has no phase information, level, or arrival time.

Therefore, it's safe to say that everyone listening to mono sounds will get the same signal and audio quality. Mono sounds are mostly used on public address systems, hearing aid, radio talk shows, AM radio stations, and mobile and telephone communications.

What is stereo sound?

Stereo sounds, on the other hand, became popular in the 1960s, although most people still used their old mono players back then. That aside, stereophonic sounds are recorded using more than one microphone. The recording microphone is strategically placed to receive varying sound pressure levels.

Moving forward, stereo signals come in specific phase relationships and levels for a smoother playback on a suitable reproduction system. However, recording stereo sound is quite expensive and needs some technical skills. Stereo sounds are mostly used in movies, TV, FM radio stations, and music players.
