recording any audio from your macosx

Ladies and gentlemen, I give you WIRETAP !!!

I bold it.  I italicise it.  And I even underline it.

The best tool ever to record any audio that can play on your MacOSX machine.  What I feel is that it just records directly from some  very low-level device or device driver I have no idea.  It's just amazing.  Go Get It Now!!!  And start recording everything!!!
