7. Using Line-In
-----------------------
If you want to use your sound card's Line-In or CD Audio inputs for
sound data (instead of mp3 files), you can do this; in fact, this
will work for any viz plugin, not just this one! Do the following:
1) CONNECT WIRES
Connect your audio source (a stereo, a live feed, whatever) into
the line-in (or microphone) 1/8" (headphone-size) jack on your
sound card. You might want to test & verify that your cable is
good before doing this.
2) SELECT SOUND INPUT CHANNEL & ADJUST VOLUME
In Windows, double-click the speaker icon in your systray (where
the clock is). Then, on the menu, go to Options -> Properties
and select the "Recording" option. Then make sure the Line In
(or Microphone) input channel (whichever is appropriate for
your case) is SELECTED (with a check mark) and that the volume
is close to, or at, the maximum. Hit OK.
3) TELL WINAMP TO USE LINE-IN
Open Winamp, and hit CTRL+L (the "Open Location" hotkey). Now
type in "linein://" as the location you want to open. (Leave out
the quotes and make sure you use FORWARD slashes.) Hit PLAY
('x' key for the lazy), and the little built-in oscilloscope (or
spectrum analyzer) in Winamp should start showing your signal.
If the signal looks flattish, you might want to double-check the
volume from Windows' Volume Control, or adjust the sound level
at the (physical) source.
4) RUN IT
Run Geiss 2 as usual. If the waves are too small or large,
either adjust the volume from Windows' Volume Control, or adjust
the sound level at the source.
