RE: audio-only alternatives for video?

Carol,
In QuickTime, the user needs to download any tracks associated with a file.
As a result in order to reduce the download for the three sets of users you
probably should do the following:
users wanting only the program audio and video:
offer a link to a video and audio version
users wanting audio descriptions, program audio, and no video:
offer a link to a version with program audio and audio descriptions
users wanting all three:
offer a link to a version with all three
In QuickTime, adding audio descriptions is pretty easy. Once these are
added to the movie with video and audio, you can just export the tracks that
you want to create the additional versions.
A link to directions for adding descriptions to QT:

If you really want to do a better job, a tool like SoundForge will allow you
to "duck" the program audio during the description, so that the descriptions
are more easily heard over whatever background sound exists.
Hope this helps,
Andrew
