Pixel Research Labs has released Ringer 2.0, an update to their iPhone ringtone creation tool for Mac OSX. It allows users to choose any non-protected file from their iTunes library or any media file on their system and turn it into a unique ringtone.
Ringtones can be saved anywhere without importing into iTunes. Version 2.0 adds manual volume control, precision selection editing, alert tones, high resolution, full screen mode, improved accessibility and more.
It’s available at the Mac App Store and the Pixel Research Labs website (http://pixelresearchlabs.com/ringer). It requires Mac OS X 10.7 or higher and costs US$4.99.
