Yes, that's great a graphic that shows frequencies truncated at 16,000 Hz on the compressed files.

There's more to it also. When I last properly tested my hearing in a physics lab back in the 1990s, 16,000 Hz was beyond my ability to hear. These days, that threshhold has dropped to around 13,000 Hz. The reason that I mention this is because even though very high frequencies are beyond my ability to appreciate, I can still hear the difference between BIAB's compressed version and the original WAV files for most of the instruments. (Distortion guitar is one that I cannot hear any great difference with.) As mentioned before, it's not huge but it's there.
