I don't understand wtf you guys are posting :lol
I'm gonna sit tight with what I have though until my album comes in 6 days. woot woot
they're just graphs that show the frequency range of a given song.
songs that are compressed always have a cutoff point where the frequency fails to go any higher. that's sound that is literally cut smooth the fuck off that you will never have the opportunity to hear. the sacrifice of a small filesize. the higher the compression, the lower the maximum frequency the chart shows the music is able to reproduce.
Examples:
Uncompressed FLAC (see it fades naturally at the top, as sound naturally should; no compresion)
^ see how everything cut's smooth off at 22000Hz? that's the compression effect.
320kbps (the cutoffs will now be obvious from here on. remember that every bit of sound above the ever-lowering cut-off point is gone forever from the music. and no, you can't simply convert it to FLAC and get it back. the sound is gone forever.)
V0 / 256kbps VBR
V2 / 192kbps VBR
128kbps VBR
the progression towards poory, harsher quality sound should be clear. this is how smaller files are created. this is why people who really care about the music are concerned about this. once the music is compressed, it can never come back.
in the case of this new Kanye AAC file, there is very little compression. In fact, I don't believe there is any, as I don't see any cut-off point that comes with 320kbps music. I'm not sure. but it's definitely superior to your typical max quality LAME 320kbps CBR mp3 file.
