A simple sound converter application for the GNOME environment. It reads anything the GStreamer library can read, and writes Ogg Vorbis, FLAC, Wave, MP3 and M4A files.

This application is somewhat less fast than various command line tools. Not a whole lot, however, and not enough to make me worry about performance for the foreseeable future. If you want ultimate performance, the command line tools are always going to be preferable.
