Xilisoft's Ringtone Maker is a downloadable Windows software program that lets you create ringtones for your mobile phone from virtually any audio file. It can extract the audio track from a video file, so you create a unique ringtone. With the built-in player, you can listen to the ringtone, trim the parts you want, and apply fade-in along with fade-out effects. In addition, the program allows you to adjust the ringtone's bit rate, sample rate, and audio channel. Furthermore, Xilisoft has designed this program with a drag-and-drop feature to help you easily create ringtones.
