[RESOLVED] Bfxr/Sfxr imported sounds seem to be muted.

Hello everyone.

I'm making sounds for my game using Bfxr, but for some reason when I'm importing the sounds I made to Stencyl they don't play, as if muted or something.

If anything, Bfxr/Sfxr exports sounds to .wav but I change them to .mp3 for Stencyl to be able to import.

Help?

Are they work good after compilation outside Stencyl? Are they mute in Stencyl both in preview and game? Have you read that: http://www.stencyl.com/help/view/playing-sounds-and-music/ ? Especially that?:
44.1 KHz (versus 22 or 11)
16-bit
Constant bitrate (versus VBR)
No metadata

I did before, apparently I missed the Audacity recommendation part. Downloaded Audacity and tried converting the .wav to .mp3 using it, and it works now. Thanks for your time and help.
