Forget about "correct" PRaT, and just concentrate on whether or not any PRaT is there. Humans react to rhythm in a way no machine will ever do (and consequently will never be reliably measured), as we are tapped into the rhythms which are found in nature all around us, such as our own regulated heartbeats. PRaT is what makes you want to dance, or nod your head, or tap your feet, or wave your arms: it is biological and this is why it is distrusted by many, who feel a need to have everything measurable by scientific equipment before they trust it. Of course, after our biological response has identified relative levels of PRaT which scientific equipment fails to detect, we can then devise or further develop the instruments which will more reliably indicate its existence or non-existence in playback equipment. Only a truly awful musical ensemble of any sort will fail to get the rhythm, and the equipment which fails to retrieve it from a recording is, quite simply, a failure. Of course, PRaT can be retrieved in varying degrees (or lost in varying degrees), and the equipment which makes arm-waving, head-nodding and foot-tapping an IMPERATIVE (assuming a system capable of transmitting this), is therefore at the top of the pile in this very fundamental aspect of music reproduction. Music, after all, is in very large part a biological and emotional experience, as well as intellectual. We have to place our reactions to music ahead of our scientific analyses.
Now, back to my IMPERATIVE Lenco! ;-)
