Ringer 1.0 released
Pixel Research Labs has released Ringer, an application used to create and edit ringtones for the iPhone. Users can import any unprotected MP3, AAC, MOV, AP4 or M4V file, which is then converted into the appropriate format. The app's interface features a waveform viewing bar, which lets users pick precise start and end points.
Clips can be set to fade in or out, and use a controlled volume through automatic balancing. The software also adjusts the amount of silence between each ring. Once a ringtone is completed, the file is exported to iTunes, where it can be synced. Ringer requires Mac OS X 10.5, and can be bought from Pixel Research for $15.
