The Nokia Music Mixer website allows you to remix your own ringtones online through a web based interface.
You can choose the loop set of your choice, move clips with drag and drop function to create your own unique mixes and add effects to it.
The custom ringtone, in AAC format, can then be downloaded to your supported Nokia S60 mobile phone through a WAP link sent via SMS to your mobile device as well shared with other users of the site.
