My own tastes being odd, I don't care for some of the overburned classics.
I am hearing the effects of two A/D samplings at similar yet not SAME rates.
That is, I can hear artifacts at the streamed 112K, which should be almost transparent with some mild swirling, but I also hear
the artifacting of the files interacting with the streaming rate to produce a new sound or "chord" in the music.
The combination of two A/D passes which are similar in frequency yet not synched will always have this.
The only way to lose this sound is to have your files at a rate much higher than the streaming rate.
Two greatly differing rates, at least. The same thing happens when a print publication re-uses a photo with a half-tone screen
and they don't line it up properly, you get a Moire pattern.
There are ways to mitigate swirling. You might decide to split difference between AM and FM sound and hard clip all high freqencies
above 10khz. The more you let the frequencies from 4000-7000 define your "sharpness" rather than 7000-up, you'll swirl a lot less.
But that's not the major problem here.
There is a warbling intermod that is very striking and odd in Undone" by Three Dog Night.
Some notes sound like they were generated by an old Bell Telephone touch-tone pad with two more rows of buttons.
I'm not kickin, I'm trying to help. At least turn down the overall brightess and re-record files with "accquired noise" "hiss, etc".
I do like the tight fit of all the elements.
Now the Cowsills and Eagles are having something like a "grinding vacuum cleaner effect" mar their voices.
Not an extraneous noise, but a effect more like the difference between two samplings being different by several hundred hertz.
There is a problem, and the more I listen I am hearing lots of added IM in program material under 1000 hz, very odd.
I'm not detecting this in in sweepers or spots, but immediately upon return to the musical program.
Maybe it's a 128kbps/112 issue. I know I gave up using 128kbps for any new files and use only 192kbps now.
Hope you can get this fixed.
