Anyone understand the concept of sampling?
Anyone should be able to appreciate that sampling gives you, yes a sample, not the entire population you were sampling. So samples can merely give you an approximation of reality, it doesn't try to give you the reality.
Anyone understand how to go from a sample to an actual value? Interpolation/approximation/guess
The higher the density of sampling, the better the approximation to reality. The less sampling, the more the interprolation into the estimate of reality and the poorer its representation is.
So who wants to listen to a recording method that samples discretely and uses algorithims to guess what's missing?
When we can sample sufficiently highly that we can't distinguish from reality, it will be great, but thats a long way to go. Current trends suggest we are sampling even less and interpolating even more.
Try the process, listen to a MP3 at varying sampling and compression rates, if you can't hear the difference, consider yourself spared the challenge of looking for the best sampling method.
