Hi Anita. I can't explain why 20% of your audio sounds tinny
but for the rest of it, I'll share what I do know. First, I don't
reset anything. I leave all settings at the defaults because I've
found that these are generally the best settings for most
occasions. I change default settings (for anything) only to solve a
problem ... for instance, I might change audio quality to "CD" to
correct a "tinny" sound.
Is there a reason why you are attaching audio to
text-captions? This is generally a bad idea, because it makes it
very difficult to get the timing right for your audio. I only
attach audio to objects (as opposed to the slide-level) for special
effects. For instance, I might attach a "ringing" sound to an image
of a telephone to avoid interrupting the main slide voice-over.
The reason there are multiple audio files is because
Captivate uses/needs the WAV file for its built-in WAV editor, but
due to file size considerations, always creates the smaller MP3 for
use in the published SWF output for web applications.
Lastly, the cost of upgrade to version 2.0 is money well
spent. Do it as soon as you can, because version 2 did include
improvements to audio handling (getting rid of that "tinny" sound?)
as well as a host of great features, like the library feature that
allows you to re-use objects from the library by dragging them onto
the current stage (slide background) from the library folder.
Have a very nice day, Anita.
