    Sound Issues

    rex@karinrex.com Level 1
      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,

          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.

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

                  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.

                    This problem is still there in Captivate 9 and Captivate 2017.

                    This is very awful

                    Kindly, consider this as a bug and fix it at asap.

                    Also, I want to add one more point, I feel 2017 has some know issues where were fine in C9. Somtimes, captivate behaves very weird.

                     

                    Thanks in advance!

                      Could you please be more specific about what audio problem you are seeing here?  It's a little unclear.

                       

                      If there are other (non-audio related) issues with Captivate, please start another thread that deals with those issues.  It can get confusing for readers of long threads if the title of the thread is not directly related to the discussion.
