I'm happy to see that you are finally seeing the light, and finally admit that quantization noise/distortion is not added separately but is inherent in digitization. Of course claiming I said otherwise suggests that someone doesn't understand the point I was trying to get across. > > The issue is simply how much additional noise is perceptible > The audibility of a signal is highly dependent on the context (whatever other signals are there at the same time, its amplitude, its spectral content and whether or not it is random (IOW a true noise) or periodic (IOW a true distortion) and thus deterministic. The following paragraph seems to consider only amplitude, and therefore it is in error. > > No hand waving here. Adding -96dB of noise to -90dB will raise the noise > floor to -91. Is that a change? Yes, is it perceptible? Who knows. > Actually someone probably does. Not you. > Given the incomplete data given, it is impossible to estimate audibility. Therefore I am proud to admit that I don't know whether it is audible because I'm being insulted and hectored with incomplete data. Anybody who really understands quantization noise, dither, and audibility will do the same. The problem is the over-simplistically stated question, not to mention the use of incorrect terminology. > > My original post invited thought and information on the subject not > knee- jerk ranting. > Your original post and its sequels had just about everything wrong, as I showed. They invited correction, which they obtained. These objections suggest that correct information was not the goal. So much for me trying to help people who can't be helped because they know little, but seem to think they know it all. Many of them hide behind pseudonyms like dr-this and dr-that which protects their ignorance. They thus avoid accountability, and can tell what ever lies and make whatever insults they wish. They can be as gratuitously insulting as seems to be their preference, without any accountability. ------------------------------------------------------------------------ arnyk's Profile: http://forums.slimdevices.com/member.php?userid=64365 View this thread: http://forums.slimdevices.com/showthread.php?t=105717 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/audiophiles
