Isn't it the impulse response of the filter he's trying to correct for? An ideal filter would have an identity impulse response (other than its low pass behaviour) - so by correcting the pre + post echo of a real filter, you get an ideal filter? with no apparent pre or post ringing
e.g. something like signal + correctionForRealFilter(signal) + realFilter(signal) = ideallyFilteredSignal Or have I misunderstood whats going on here http://www.ayre.com/pdf/Ayre_MP_White_Paper.pdf -- Grahame ------------------------------------------------------------------------ Grahame's Profile: http://forums.slimdevices.com/member.php?userid=1200 View this thread: http://forums.slimdevices.com/showthread.php?t=69145 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/audiophiles
