Overview
If you like to customize your phone, River Past Ringtone Converter is the ideal software for using any music as ringtones.
Convert from almost any audio format to high quality AAC or WMA ringtones for your iPhone, Blackberry, Walkman, or Windows Mobile.
Extract audio from the standard AVI, ASF, WMV, MPEG-1 and MPEG-2, RealMedia, and the not-so-standard QuickTime MOV and MPEG-4.
If the file format exists, we probably support it.
