The TuneLings application’s audio functionality works on any audio file, with or without a TuneLing to match it. This makes it useful as a play-along practice or transcription tool for any musician or singer, on any instrument – for free! The TuneLings Media Library shows all the audio files that you have, with or without TuneLings.
To add a song to the library, just drag it from iTunes or your desktop into the bottom section of the Media Library window, seen in the illustration to the right. If there is a TuneLing already available for that song, a “Buy TuneLing” button will appear beside the song name to let you know you can get that TuneLing right away.
