'''Noise shaping''' is a technique used to "push" some of the noise in a signal to a part of the spectrum where we can't hear it. This doesn't decrease the amount of noise in a signal, it just makes it less apparent to any human listeners. It can be used in a variety of cases but is absolutely necessary for example when using [[Sigma Delta Modulation]] (a sampling technique used with [[SACD]]'s). | '''Noise shaping''' is a technique used to "push" some of the noise in a signal to a part of the spectrum where we can't hear it.
