clearly not white – switching, say, from SNS1 to SNS4 sounds like shhhhh..ssssss as the noise is
shifted towards the higher frequencies. However, this is not really a meaningful test since the
sensitivity of the ear at different frequencies is very dependent on level, and the design of the more
extreme shapers is in any case intended to render the noise floor completely inaudible at normal
listening levels. Ultimately, the only 'right' choice of noise shaper is the one which sounds best for the
material. SNS2 is a good starting point for most situations.
The Prism Sound SNS logo shown above is found on many of the world's finest CDs, and is
