Published Captivate; slides have washed out audio

[devidas]

I have captivate 4.0 and I created four (all are high audio quality-mono) audio files (mp3), each file for each of the four slides in my captivate.

I imported each of the four mp3's into each of the slides.  I publish the project at the 64kbs, 44.10khz audio rate.

The problem is the audio sounds bad, kind of washed out in the published Captivate.  Any idea of what I need to do to improve the audio?  64kbs is a decent audio data rate, it should sound pretty darn good.

Your insightful comments are very welcome....

I've had poor luck with importing MP3s into Captivate.

My pseudoTheory is it's due to recompression - Captivate is recompressing my already lossy audio files.

So I import .wavs into the CP project (generally 22khz, mono, 16bit), which does make the project a bit bigger, but the resulting published audio is a lot cleaner as well.

Erik,

Thanks... I think I learned this lesson a long long time ago and forgot it, until now.  Thank you, I will try it!

Erik,

OK, I tried originating the wavs as 22khz, mono, 16bit, then importing them into the Captivate (4.0).  Then publish at 64kbs.  The sound was just as bad as before.  It sounded 'swishy'. 

If I originated the audio files as 44khz, mono, 16bit, the sound was a little better than the 22khz, but not much.

If I publish the captivate at 96kbs audio rate, the sound is better.

However no matter what, the sound is still a bit 'swishy'.

Hello,

I have been having popping and poor audio quality with my audio files in Captivate 4. The audio sounds good before I import it but once I publish it I still have issues.

I was able to correct this problem by importing the audio into Captivate 3, saving the file, and then within the CP4 file, going to File - Import - External Library. Then drag the imported audio to the library in your CP4 file. That seemed to eliminate audio issues I've had.

Hope this helps someone

From Doug's reply then, sounds like just a poor conversion issue with CP4....though the few CP4 projects I've done with audio don't seem to have the issue.

Could it be related to the 'bad .dll' thing?

Hello,

The patch did not correct my audio issues, I still have to use Captivate 3. Will there be a future patch to address additional audio issues? Mainly I hear popping noises within Captivate but if you listen to the imported audio file outside of Captivate 4 it sounds fine.

Thanks!

Hi Doug

Sorry to hear the patch failed to help.

Please report this to Adobe as a bug so they will be aware. (Link is in my sig)

I found ther same issue - we just purchased Captivate 4, so should not be a version issue.

Anyway, a co-worker lent me a SWEEET little Olympus digital recorder. It even has a self-contained usb plug, so I cna dump stuff right off it to the computer,   I upload tracks to slides for FAR crisper sound.
