Ability to transpose attached audio files.
To be able to transpose the attached audio mp3 files to enable it to play in another key. This feature is standard with Karaoke programs so I know it can be done. Place the user option where you choose the file in the Add "Play" Transmogrify Button using Transpose steps between -5 to +5.
