stereo settings

[aaron76]

Could someone explain to me what the stereo settings are for? I mean, I understand stereo and mono of course, but what are the advantages of the other settings?
Thanks.

Re: stereo settings

* Stereo - you have two ears? then it stands to reason that audio should be made from two channels. Stereo is the most widely used, and matches Audio CDs.
* Mono a recording with only a single channel of information. A question that is often asked 'why is my 128kbps encoded Mono file, the same size as a 128kbps encoded Stereo file?' The answer is simple, to keep the kbps rate constant the mono file is encoded at twice the quality rate as the stereo file (kbps measurement is for the whole recording regardless of the number of channels, so Real kbps per Channel = kbps / Number of Channels).
* Joint Stereo - If you were to take sound from the left speaker and compare it to the sound leaving the right speaker, you might find there was significant similarities between left and right channels. This similarity can be taken advantage of to reduce encoded file size.
