iight Imma help you out a bit

here's what the main buttons are

make sure you click the r & the little red circle button at the bottom of audition
click the r again after your done recording to keep your track 1, track 2, track 3, & so on

after your done recording whatcha gotta do is master & mix your vocals
...but I can't find the mixing thread from back a while...
but thats how you record vocals

[DƎRDYPK]

yeah mastering is pretty much editting your vocals & making em sound better with effects
& mixing is just turning up your volumes right
