Erm I am having problems with my flash after when I export the movie. I have reedited my wave and mp3s (trimming them since I need only some of the sound effects in it) But after when i exported it, the sound’s quality doesn’t seem to be as good as before (sounds muffled and a bit blur). So I want to know is there anyway to prevent this? Also is there any recommended freewares to edit trim mp3s? Help would greatly be appreciated. =) ---

if you mean by trimming what i think: > **[Audacity](https://sourceforge.net/projects/audacity/)** > > Download Audacity for free. A free multi-track audio editor and recorder. Audacity is a free, easy-to-use, multi-track audio editor and recorder for Windows, Mac OS X, GNU/Linux and other operating systems. The interface is translated into many... works great for me scotty(-: ---

I would recommend using .wav in your fla IF it’s a loop. MP3’s seem to add dead sound on the end so it never loops properly. In the library, select a wav or MP3 then click the _i_ [information]. From here choose MP3 and best then adjust the Bit Rate by ear.
