AimOne Ringtone Maker is exactly what its name suggests: an application that helps you generate tones for your mobile phone. This type of utility comes in handy to users who get bored of their default ringtones and wish to create new ones from their favorite songs.
The program is very simple to use and configure. You can import multiple video and audio files, use the integrated sound player to pre-listen the trimmed tunes, and choose from output formats like MP3, M4R, M4A, OGG, WAV or AMR.
Another good thing is that you can choose individual output profiles when converting multiple files at the same time. You can also select the preferred channel type and opt for the perfect sample rate and bitrate values.
My only problem with this program is that it doesn't provide you with Fade-In and Fade-Out sound effects. These two options might prove to be of good use to some people.
To summarize, you should buy AimOne Ringtone Maker only if the aforementioned flaw doesn't mean much to you. Otherwise, I'd suggest you try a different ringtone creator or an audio editor to generate phone tones.
