Mr. Krueger, I have no idea why you are raising my name in newsgroups to which I do not subscribe, hence my crossposting this response to r.a.o. However, to examine this statement of yours above, the discussion to which you are referring involved your claims that the "room sound" on live recordings would act as dither, not "tape hiss." As was pointed out to you at the time by others, this background noise is far too "red" to provide any dithering action. With respect to tape hiss or even electrical noise, both of which are "whiter" in color than acoustic backround noise, whether or not these can act as dither will depend on their exact level and spectrum. I don't believe I have said otherwise. What I have said is that if the noise is too far above the digital noisefloor, then it will be treated by the ADC just as any other component of the original analog signal. Sincerely John Atkinson Editor, Stereophile
