The technical thing you need to know is that you cant just remove 1/2 of the samples this could give you horrible artefacts often called aliasing or "mirror frequencies" or folding . other methods are needed and SOX provides this . what it does is to "filter away" frequencies that are "to high" for the new lover sample rate before "removing" 1/2 samples . This is apparently an artform and SOX considered good at it. And I have not delved in the details of it I'm just vaguely aware of what's involved . It is probably done equally well by other software too, but as SOX is filled with all kinds of selectable options and filters it is very flexible and also suitable to integrate with other software. Some Tinkers love it because you specify what ever you want if you now what to do (or think you know ). -- Mnyb -------------------------------------------------------------------- Main hifi: Touch + CIA PS +MeridianG68J MeridianHD621 MeridianG98DH 2 x MeridianDSP5200 MeridianDSP5200HC 2 xMeridianDSP3100 +Rel Stadium 3 sub.
