Make any other adjustments you want to the ringtone, such as adding a fade-in and fade-out portion. Press 'Shift-T' to trim the song so it only includes the selected portion. If necessary, you can press 'Ctrl-1' to zoom in on the track and adjust the selection more precisely. It's okay if the selection is shorter than 30 seconds, but it must not be any longer. Audacity will play back only the selected part of the song. When the selected segment is roughly 30 seconds long, release the mouse button. When you reach the point at which you want the ringtone to start, press 'Pause.' Click with the Selection tool exactly where the tracking cursor is located and, without releasing the mouse button, drag to the right to select part of the song. Press 'Play' and listen to the song, paying attention to where the tracking cursor is located.

Launch Audacity and open the song you want to use as the ringtone. This gives Audacity the ability to open and save files in the AAC format, which your iPhone uses for ringtones. Download and install the FFmpeg import / export library for Audacity (link in Resources).
