As its name implies, this simple yet efficient utility enables you to create ringtones for your iPhone device. You can use this program whenever you get bored of your current phone tone and have a new favorite song you wish to set as your default ringtone.
The application lets you import songs from your iTunes library or work with the built-in audio recorder to create a personal audio file. You can use the integrated sound player that also shows a waveform representation of the input file to easily select the segment you wish to transform into a ringtone.
Furthermore, this program features Fade-In and Fade-Out effects, which you can apply to the selected audio segment. I also like the fact that iSkysoft iPhone Ringtone Maker provides you with options to automatically send the generated ringtones to your iTunes library or iPhone.
My only issue with this application is that it supports a limited amount of input formats. For instance, you cannot import AU, FLAC or AIF files and generate iPhone ringtones.
To conclude, it's worth acquiring iSkysoft iPhone Ringtone Maker on your Mac only if the aforementioned flaw doesn't mean much to you. Otherwise, I suggest you try another utility when you need to create ringtones for your iPhone.
