iType is a software tool that allows users to create "notes" on their iPod by adding audio files of letters and numbers to their Playlist-on-the-go. These audio files are 100ms long and inaudible to the human ear, so they won't interrupt the shuffle feature. Users can create words, phone numbers, or any other desired phrase by adding letters and numbers to their playlist. It is recommended that users create a new playlist specifically for these audio files for easier access.
