Audiveris is a complete music scanner going all the way from the scanned music sheet input to the MusicXML output. Audiveris is an Optical Music Recognition (OMR) module. Starting from the image of a music sheet, it provides high-level logical music information compliant with the MusicXML definition. Other tools such as a Midi Sequencer, or a Composition Editor can then read and update this data.

There are already commercial tools in this area but Audiveris is, to our knowledge, the only open-source OMR tool. It is a cross-platform tool, written in Java, and tested on Windows and Linux. Mac OS would require a volunteer.

Audiveris works with printed music sheets only, the task of recognizing hand-written scores being significantly harder.
