Basically you have an analog signal (guitar, drums, whatever) and when it goes into your pc it needs to be converted into digital. Digital has limitations and one of those limitations is that it only simulates a true analog wave. The sample rate determines when the pc samples the input voltage. The higher sample rate the more often the signal is being measured giving a better image of the analog sound. Each time it samples it makes a digital representation of the input voltage. So basically what you hear from CDs and your pc is lots of little square waves instead of a smooth analog wave. I hope you understand this its sorta hard to explain well you really need a picture to understand the difference.
Also 48KHz means that it samples 48000 times a second where as 96KHz is sampled 96000 times a second. Higher sample rates end up as bigger files as well so u can fill your hdd quickly using the higher rate.
When mixing pros tend to use the highest sample rate and bit depth they can so when they mixdown there is a higher clarity.

Well I've honestly never heard anyone try it but I can promise you that my "cutting the # of samples in half" line was still a gross over simplification of the process and there we're certainly still be artifacts.blackcom said:Going from 88.2 to 44.1 would just be taking half of the samples, or cut in half as like when going from 96 to 48.

In regards to the bitrate question, the sample rate effects the bitrate, but the bitrate does not effect the sample rate. The bitrate tells you ampltitude accuracy (dB) while the samplerate is measure in time or frames. The amplitude is only measured when the sample is taken. So when you change the sample rate your DAW or whatever makes assumptions about what is going on in between the samples.
When you do a bitrate reduction you lower your accuracy, but most software and hardware adds dither (basically noise) which smooths transitions in between bits. So the long and short of it is that you are defineitly losing accuracy in a bitrate reduction, but not nearly as much. BUT, you need to consider that if all of your tracks are 24 bit and you are 24 bit right up until the two track stage you will gain accuracy over recording 16 bit the whole way b/c the individual tracks will maintain much of their accuracy. This is b/c amplitude in the mix is cumulative so as long as there are other things going on in the mix the accuracy of the individual tracks could stay mostly intact. Once again I've grossly over-simplified.
