Anyone know the difference between joint and stereo channels?

I have a piece of software called Switch File Converter which, under Channel Encoding Mode, offers the choice of (i) Stereo, (ii) Joint, (iii) Force and (iv) Mono options. The default is Joint.

I have learnt not to trust default settings. I am aware that Wikipedia has an entry, but it does not suggest which to use (joint or stereo) and when.

Thanks in advance.

What I found by Google gave me the impression that "joint" should produce a smaller file with the same sound quality (or a better quality with the same file size).

Joint stereo—Unlike stereo, joint stereo employs real-time bit allocation techniques that dynamically assign bits to the channel and frequency bands that need them most. This results in wider bandwidths and better dynamic range. Joint stereo does manipulate left-right separation and sound stage; however, any spatial blending performed is in frequency bands where the human auditory system would normally blend the stereo signal. Joint stereo defaults to true stereo if enough bits are available. Note that real-world listening tests awarded higher scores to Joint Stereo than to discrete at low bit rates.

Stereo and Dual Mono—From a coding standpoint, these two modes are identical. Half of the total bits available from the transmission line are allocated for the left channel and half the bits are allocated for the right channel. Left is always left, right is always right. No blending, no sound-stage manipulations.

Does this mean it is better for low and not suitable for high bit rates?
