Editing Audio Files in Engage - Appears to increase file size

Jun 20, 2012

I was recently investigating why my file size of my course was rather large ~123MB and look at some of the larger Engage Interactions. I noticed one that was almost 40 MB. It is a guided image with approximately 1.2 MB of images, 4 and 4 MB of audio. I know that the Flash animations will add to it but didn't expect it to increase 10 times larger. I decided to rebuild the interaction from scratch to see if there was any additional hidden images or audio. I rebuilt it and the file size came in at just over 9 MB and I assumed it was OK. I noticed two of the images had a slightly louder audio volume then the others. I made adjustments to the the two guided images with the slightly higher volume. I went back to look at the new file size and it increased by 4 MB.

Does Engage or the audio editor function create duplicate audio files when adjusting in the editor, hence increasing the file size? Is this a known issue and what can be done to still utilize the audio editing function without seeing my file size explode?

Thanks,

Dave

Hey Peter,

Thanks for your reply. I have spoken with my manager about sending over the course, however due to confidentiality/proprietary information I cannot send you the entire course. She did state it would be OK for me to send over to you a portion of the course if that will work. I can send over to you the Engage Interaction in question, both the older (larger) version and the newer (smaller) version I rebuilt, in a Presenter file.

Will that work for you?

Dave

Sure, that'll work! And just a quick question: how are you saving the files - locally, or to a network drive? I've seen some issues with file sizes blowing up when they're saved to a network or USB drive, so that's the first place I'd check.

If not, we'll look forward to getting the files Thanks!
