You can interpolate very accurately depending on how much horse power you have. It's done all the time in many applications. Is it the same as recording at the higher word size, no. Can it be better than the smaller word size, yes. Your DAC effectively interpolates it in real time to an infinite resolution (analog). By doing some work off line you can allow the DAC to do a better job. And you don't have to do it in real time (you can use higher order fits [linear, quadradic, cubic, ... etc.]). We do it all the time with a digital signal off our instruments. We fit a curve then use that curve to find the center of the peak. The higher order fit the more accurate. It better represents what the real analog signal was. Is that "made up", no !!!. Is it better than measuring the signal at a higher rate, no. Can interpolation be done poorly and make it worse, yes !! -- mswlogo ------------------------------------------------------------------------ mswlogo's Profile: http://forums.slimdevices.com/member.php?userid=9090 View this thread: http://forums.slimdevices.com/showthread.php?t=34597 _______________________________________________ ripping mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/ripping
