I don't have adobe in front of me now, but here's how it's done. The
names of the various windows is probably wrong, but you'll get the idea.
Read the keyframe section of the help file for the nitty-gritties...
1) Double-click on the audio file (on the timeline) you want to fade,
this will open up an audio editor window.
2)Move the current position marker (the red line on the timeline) to
where you want to begin the fade. On the audio editor there will be a
volume slider. Click on the "new keyframe button, which will mark the
beginning of the fade. DO NOT alter the volume level at this point.
When you do this a diamond should appear in the timeline portion of the
audio editor window.
3) Move the position marker to where you want the fade to end. Make
another keyframe, but this time adjust the volume to the volume you want
at the end of the fade.
Adobe will automatically scale the volume between the two keyframes when
it renders the video. The scaling is linear (i.e. if the fade occurs
over 10 frames, then the volume will be reduced by 1/10th each frame).
If you want non-linear fades you have to add multiple keyframes, and
adjust the volume appropriately for each frame. Although the changes
between each keyframe is linear, you can approximate other fades
(exponential, sine, etc) somewhat accurately this way.
