I have a sound clip I'm using for a project and I've checked it in both Soundbooth and several media players to make sure it's properly looped and it's fine. Only problem is that when I go to put it into PowerPoint, there's a whole second or two where it simply stops before restarting. Is there a way to correct this so there is no delay or do I just have to edit the file to make that falloff less noticeable?
