Sound Issues

When I record and then play a module using the PC speakers, it sounds great regardless of volume level. When I record and then play a module wearing headphones, there is a low buzzing noise (electrical hum) in the background the entire time (regardless of which headphones I use or what volume level I have set). Any ideas on how to solve this (as I do not know whether my users will be using headphones or not).

Thanks in advance,

PC speakers are awful. Headphones typically give more complete sound
reproduction. So you are hearing what I'd expect you to hear.

I worked with sound files recently that a colleague recorded. They sounded
fine to her, but hideous through my headphones. Dropping the files into both
Audacity and Soundbooth showed that the buzzing was all in her recordings.
We worked a little to reduce the noise in her recordings, but ultimately I
still had to reduce the noise and normalise the sound with software before
it was usable.

OK, Rick. I have Adobe Soundbooth so I will try that.

Hi Karin

Have you confirmed it's the Captivate project? What I mean is to ask if you have tried running the captivate project on different machines and using different headphones. I'm asking because I could fathom the possibility that it's simply an issue with one PC and the headphones.

Cheers... Rick

Thanks, Rick. I've confirmed that it's not my headphones and not just on that particular PC. It's a very bad buzz...I cannot publish it sounding like this. :-(

Any other ideas?

Hi Karin

Hmmm, the only thing that comes to mind is to try recording using a different application such as Audacity. See if it records sans the hum. Then import the files into Captivate.

If that seems to work without issue, consider reporting to Adobe as a bug.
