An MP3? That would depend on how long this clip would be. Sound files are always relatively large, although an MP3 should be managable. If it is a half an hour or longer, though, J2O may not be the best place. I'm not exactly sure of the correlation between length/quality and size for MP3s, nor the J2O bandwidth limitations of late, so you probably should get permission from someone who knows more about that sort of stuff like FQuist before doing this.
