     Comp.sys.apple2 (csa2) is an Apple II newsgroup. You should be able
to get more expert help on an official Mac newsgroup. Even so, people
here use Hyperstudio, too, and have had experiences with recording
sounds. Perhaps the following will help ...
 

     There are several ways to get "static" when recording via a mike.
One is to have incorrect settings for the sound recording program. If
input level is set too low, you may be recording relatively more noise
than sound from the mike. If input level is set too high, you may be
getting "clipping"-- the signal gets chopped at the peaks-- which can
sound like static.

     Also, check the Sampling Rate setting. A too-low sampling rate can
result in glitchiness which sounds like static. If you have not already
done so, try experimenting with your sound recording program's settings.

     If your sound input board has more than one input, then, one may be
for "Line Input" (e.g. for recording from a tuner, tape deck, etc.) and
another may be for "Mike". If there is a choice, be sure your mike is
plugged into the correct input.


     Another possible problem area is your microphone. Static can come
from a mike which is damaged, has some sand, etc. sitting on the
diaphram, has an intermittant ON/OFF switch, has a damaged cord, or has
a loose connection at the plug.

     Or; you may be using a perfectly good mike which is badly
mismatched to your sound input board. For example, a high quality mike
may deliver a very low output. Your input circuit may auto-boost
amplification to try to compensate; but, the result may be to obtain an
audible recording with greatly increased noise. (Your signal-to-noise
ratio at the input is too low.)  By the way, the mike supplied with
Hyperstudio (the Apple IIgs version) is not an especially high quality
unit; but, it works fine with Hyperstudio's GS sound input board.

     If you are not sure that your mike is okay and is the right sort
for your sound input board, try swapping in one from a tape recorder,
etc..

     Good luck!
