The latter is a measure of filesize and download time and also a rough measure of quality.
Note that 'sample rate' or frequency, measured in kiloHertz (kHz), is not the same as 'bit rate', measured in kilobits per second (kbps).

Joint-Stereo, rather than Mono or Full Stereo.Constant Bit Rate (CBR) rather than Variable Bit Rate (VBR).The short version follows, it is explained in greater depth below:
Flash requires the audio to be in a fairly specific format and this happens to also ensure the widest possible compatibility in other situations e.g. The Media Filters in Moodle use Flash to playback audio in the browser. It can however, in some rare cases cause your MP3 files to sound faster and higher pitched, making normal speech sound like Minnie Mouse, or slower and lower pitched. Turning this on is recommended, and is a job for your Moodle administrator. Moodle has a facility called Multimedia plugins that can make the presentation of some kinds of downloaded audio and video files more streamlined.

To determine when to switch to mid/side stereo, LAME uses a much more sophisticated algorithm than that described in the ISO documentation, and thus is safe to use in joint stereo mode. To much switching between mid/side and regular stereo can also sound bad. Using mid/side stereo inappropriately can result in audible compression artifacts. In joint stereo, the encoder can select between Left/Right and Mid/Side representation on a frame basis. This will effectively increase the bandwidth if the signal does not have too much stereo separation, thus giving a significant gain in encoding quality. The signal will be matrixed into a sum ("mid"), computed by L+R, and difference ("side") signal, computed by L-R, and more bits are allocated to the mid channel. In this mode, the encoder will make use of correlation between both channels. give one channel more bits if the other contains silence or needs less bits because of a lower complexity. It can, however, negotiate the bit demand between both channel, i.e. In this mode, the encoder makes no use of potentially existing correlations between the two input channels. Joint-stereo is the default mode for input files featuring two channels. I found this info, which maybe helpful in choosing the right stereo mode> Just wondered if anyone here has experimented with the stereo formatMP3 rip settings to see what gives the best rip results ? There are a number of different stereo settings e.g Joint stereo, dual stereo, stereo, forced joint stereo.
