Who took my high frequencies?

Warning lots of pictures.
Also note this isn't about how is sounds it's about how much data you lose.

WAV

love it. what is the implication of losing data though? does the shortening of the decibel? scale mean you have a reduced volume range?

Where it's black a signal is gone. What what the compression is doing at the higher bit rates it just cuts off the stuff above 16khz then it starts taking from below when it's in the 128kbps bit rates range. 30 - 17khz is a common range for hearing for under 30s.

FLAC ftw. You playing around with audio codecs again? Cool to see the data in action.

Mostly because I'm upgrading most of my music to 320kbps MP3 via Play Music and was wondering how iTunes match would compare.
