I have a preset I made that makes the person talking sound like it is coming through a phone. I have used this preset many times but I have stumbled across a file that will not allow me to apply it. I tested it on other .mp3 files in that same project and it attaches fine. I then tried just to apply any audio effect to this troubled file and nothing will snap to it. Any ideas why this is happening? I did need to convert this from a .amr to .mp3 but the file plays fine.
Actually after doing some more research in the project it appears I cannot add an effect to any "mono" .mp3 files but "stereo" works fine. Is there anything I can do to apply the effects to a mono file?
Looking into convertering mono to stereo...I think this will be the way to go.
That was it...I needed to modify the mono files to stereo. Cool.
