I have a problem claiming decorrelating when working on random (music) signals. I understand the principle when talking about sinusoidal signals that repeat for some period of time. But I can't see how decorrelation benefits a one time transient signal. Quantization error prevents you from perfectly reconstructing such a signal with any more precision than the quantization step size. Maybe a mental block on my part...
