I figured that by shortening the sample from 2 minutes to 20 seconds I might persuade the software to work for rate correction, and the card not to drift so much. Without sample rate correction the correlation of two recordings of the same CD (analogue out) on the exact same kit was of the order of 30db. Sample rate correction does work on this shorter track, and improves the correlation to around 35db. Comparing the CD to a CD rip, with correction, for the same short section I now get correlations around 27db. I guess I could get some useful comparison data at this level of correlation, so may try a bit more..... -- PasTim ------------------------------------------------------------------------ PasTim's Profile: http://forums.slimdevices.com/member.php?userid=41642 View this thread: http://forums.slimdevices.com/showthread.php?t=84742 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/audiophiles
