Question

Audio Playback Diffferences (HTML vs Flash)

I recently created a module in Captivate 8 on Windows 7 that included audio on each of the slides. When I played it back in Flash format, all the audio was clear. When I played it back in HTML format, however, the audio had some additional noise (clicks). Does the HTML handle audio in a different way than Flash? Is there anything I can do to keep the clicks from playing in the HTML version? I tried adding some additional space before the audio starts on each slide. That did not appear to make a difference. Any suggestions are appreciated.

Thanks,

Darin

Fundamentally, it does!

Remember, in Flash, nearly everything is packaged into that singular SWF file. (Video content is stored externally and referenced I believe)

In HTML 5, the audio clips have to exist as separate files that are loaded into memory when they are needed.

The end result is that with either format, audio hopefully plays as expected. But there could be something about the HTML 5 load process that is triggering that click sound as the audio clip loads up.

Rick,

Thanks for the breakdown. Given that information, is there any best practice when working with audio in HTML5 modules? Is there any way to set a preloader for the audio? Should I remove any silence before the audio starts? Just grasping at straws here.

Much appreciated,

Darin
