Pink Floyd: Hey You, 1979, studio

  This comes from the MFSL release of The Wall and it is an example of quite a new studio recording.
I took the snapshot at 1:23min (at about the moment when the sound gets thicker after the guitar start)
 
1. original sound/lossless compression

 
2. mp3 compression (320kbps, BladeEnc. 0.91)
Mp3 / 320kbps - the very top treble frequencies are getting harmed.

 
3. mp3 compression (160kbps, BladeEnc.0.91)
After pushing to 160kbps all frequencies over 16,5kHz completely disappear.
