What would produce this swishy effect? 2020-02-28 20:23:33 Attached are two samples of the same section, of the same song. (No One Lives Forever, the Boingo Alive version by Oingo Boingo)I can hear a distinct swishy noise in the Amazon version.What sound processing would create this effect, and would there be any chance of cleaning it out? (similar to hiss removal)I've encountered several tracks on Amazon that have this same swishy noise added to them over the years, first in mp3 downloads, now in their streaming service. The ratio seems to be about 2 in 10 albums (that I listen to anyway). If the mp3 had it back then, the lossless streaming has it now, unless it's a 'Ultra HD' track.
