Nope, works very well and supports the full bit depth and all the channels the device offers.Any known issues or limitations with CoreAudio on macOS? That's where I'm using REW. So far I've not seen any problems with dither.

Inter-Sample PeaksWhat is ISP?
I keep reading it and can't assign a word to the "P", which makes me a bit unsure about the "I" and "S".
Inter-Sample Peaks
So what is your result on this test?Yes. Looks like this, happens when there is a fast amplitude change between samples and sample amplitude approaches FS.

Iv enjoyed this thread
As for the question about old versions of Audition or the final version of Cool Edit Pro is reliable or not
Yes, Audition and Cool Edit (the first one I have used is 1.1) are good at these things, and good for simple destructive editing. After all, these are tools, people with talent and skills can do great things on Windows Paint, while others can create crap out out of Photoshop. It depends on how the tools are being used.Talking of "old" versions, the SRC Comparisons page is interesting.
Of course, I don't know/recollect if there's any settings that might have been missed in the old version of Audition. For Audacity version 2+ set to "Best Quality,", the sweep plot looks very similar to Audition 2019 Some of the results on that page are truly dire.

Remember my chip tune post?Of course such signals can appear on recordings, but it maybe it should be kept in mind that's not a bandlimited square wave.
(Top is, bottom is a "naïvely" generated square wave.)

What is worse is some of those dire results are still in some DAW software and used to work on recordings. YIKES!Talking of "old" versions, the SRC Comparisons page is interesting.

(N.B. Audition 5.5/CS6 SRC looks identical to Audition 2019.)

Indeed. I have the same result as yours. Perhaps it is just a stored snippet of an audio file.
You might not remember that CoolEdit came with a MS Visual C SDK back in the day where you just edited a plug-in "skeleton" and did a one click recompile. I wrote a plug-in to do a third order spline click repair that still works today.

What is the true peak value in your analysis?
But here is something I usually observed these days:Of course I remember your chip tune post.

And here it is again with brickwall dBTP limiting (threshold at 0dB, scaled on output by ~-0.1dB):

See whether or not the limiting has "ruined" the sound quality... or not. ;-)
e) what arbitrary frequency (~1KHz) hits the most 16 bit theoretical values (exercises all the levels @16/44.1) as that is the one I figure I want to use.
