iType is a collection of letter and number titled audio files that you can use to create "notes" on your iPod, using the Playlist-on-the-go feature. Each audio file is 100ms long (less than a second) and is .01Hz (a frequency that humans can't hear) so it will not interrupt your shuffle function. To create a new "note", simply add a letter/number to the POTG playlist to spell out a word/phone number/anything else you may want to write, like "ripe banana". It is suggested that you create a new playlist on your iPod with all of these letter/number files on it for easier access. Note: Your iPod must have POTG function to use these files to create "notes" iType is freeware. The idea came from PodType, another very similar, almost identical set of files. Unfortunately, PodType is no longer availible, and so I've created iType v1.0 to replace it.
