PhoneZoo is a new service that allows you to upload any audio file, clip out a part of that file for a cell phone ring tone and share that with other users. There are two things that are notable about the service; the first is that unlike some other lightweight services like this PhoneZoo actually works, the second is how the company handles use of copyrighted music.

PhoneZoo scores high on ease of use, users set the duration of the tone and drag a marker over the segment of an audio file they want to excerpt. Metadata for sharing can be provided, copyright status of the file is asked and with one click a link to download the ring tone is sent to your phone.

On the copyright question, PhoneZoo lists two types of ring tones available for sharing. Public domain files can be downloaded by anyone. Ringtones from copyrighted music can be listened to, discussed, searched for - but not downloaded until you upload a copy of the whole song yourself. It’s an interesting way to get around having PhoneZoo held responsible for copyright violations.
