I am 99.99999% certain that Pat has not suggested that normalisation will involve compression. He understands fully what the implications are. The simple fact of the matter is that if you try to apply a linear amplitude adjustment to a digital recording, then unless the adjustment factor is an exact power of 2, you *will* incur some degree of rounding error. This is nothing to do with compression: it is in principle *impossible* for any software to perform normalisation that avoids rounding errors.
That said, let's be pragmatic about the issue. The audibility of the rounding errors that are introduced by normalisation is vanishingly small compared to the much grosser effect of actually changing the volume. I have over a decade of experience in digitising LPs, and I would be very surprised to hear that anyone was able to successfully ABX normalised v. unnormalised recordings of an LP (after level matching, of course). Nobody should lose sleep over it: in practice, normalisation is a benign operation. -- cliveb ------------------------------------------------------------------------ cliveb's Profile: http://forums.slimdevices.com/member.php?userid=348 View this thread: http://forums.slimdevices.com/showthread.php?t=21836 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
