I dunno much about WMA but it seems to compress twice as better than
MP3 while retaining the same quality, no seriously, I got 32 kbps
audio samples that MP3 can't preserve below 96, my guess is that it
makes multiple passes (since it takes up more CPU to encode/decode) to
detect repeating, redundant parts of the song (multiple verses etc.)

Also no offense but it doesn't look to me that you know jack shit
about digital audio and compression in general, and neither do I on a
large scale -- so fuck it.

Not sure what you think you discovered though, it's sure as hell
possible to encode at 20 kbps with 44.1 KHz, what's the point of that,
though? The only thing suitable to encode with that preference is a
casual telephone convo.

Fuck you of you idiots. It's getting hard to tell where his ass ends

I'm not the one with a name like "Tommy Tucker,"

"FUCK YOU OF YOU IDIOTS!!!"

Lol... Next time, don't drop outta school.
