RetroCode is a universal mobile content converter originally created by Retro Ringtones LLC. RetroCode is able to read and write most common sample based ringtone formats including meta-data.


RetroCode reads and writes many common mobile sample content file formats. RetroCode takes measures for making sure that meta-data is maintained and converted between the formats. It features filters for adapting audio content to the abilities of small handheld devices. RetroCode also includes a ringback-signal synthesizer allowing to mix audio content with standard ITU ringback signals.
