User:Ryan Cooley/MPEG1

MPEG-1 articles (MPEG-1, MP1, MP2, MP3) on wikipedia are complete crap. Disorganized It's far easier to start a new one than try to fix all the individual existing ones, and will give far better end results; I will copy some content.

Do not make any changes to this page This is my mind-dump and accommodating others before I'm done will just make much, much more work for me. All suggestions will be ignored (for now).
