<< please what?
ive seen graphs before... 192 drops basically everything above 15kHz...even with a nice encoder like LAME. 256 is VERY close to CD quality. You'd need some incredible equipment to tell it apart from CD.
However I can tell a diff between 192 and original CD on my equipment... >>
i don't really care what a graph tells me. the extent i use those graphs is when i'm choosing which encoder to pick. (i figure, why use inferior codecs, all things being equal). but in terms of encoding at 256, that kinda almost defeats the purpose of having mp3s, so i usually stick with around 160 vbr. i could probably tell a difference too using my headphones, but i mean, why should i even try it when 128 sounds good on its own? it's not like i can tell the difference without directly comparing them. (talking personally here, all you sensitive ear types don't get your underwear in a bunch). ignorance is bliss no?
i see mp3s as good for two things
size
convenience
not:
audiophile sound quality
that's my story and i'm sticking to it
