Hey guys. I need some help. I made an animation but it's not that great because it doesn't have sound effects. So I go to stickpage to look for some and I found it (TNX Stone! :D). When I finished placing the effects and I press enter, It sounded great. But when I pressed ctrl + enter, it sounded different. Please help.

umm try searching publish settings and increase the quality of the sound or MP3
EDIT:do this Ctrl+Shift+F12 and increase the quality

How do i increase the quality? Do i click "flash" and set the "audio stream" and "audio event" higher?

yes you click flash and increase both audio stream and event cuz that's what i always do

Yessir, in publish setting you should set both of those (or just one if you're only using one) to 128 or 160 and "best" instead of "fast"
