I hope not, I was able to sample audio from the tape recorder jack
on my Apple II in 1979. Check out the Sound Manager chapter of
Inside Macintosh, volume VI, the section on recording sounds directly
from a device - this'll get you crummy 8-bit sampling, which may not
be good enough for your needs. Of course, make sure you have a Mac 
with a sound input jack first!

There's also a large selection of A/D boards you can add which do
all sorts of things. Try National Instruments, or any music nerd
