Library for rhythm transcription integrated in the assisted composition environment OpenMusic.

Functional Description. Rhythm transcription is the conversion of sequence of timed events into the structured representations of conventional Western music notation. Available as a graphical component of OpenMusisc, the library OMRQ privileges user interactions in order to search for an appropriate balance between different criteria, in particular the precision of the transcription and the readability of the musical scores produced.

This system follows a uniform approach, using hierarchical representations of timing notations in the form of rhythm trees, and efficient parsing algorithms for the lazy enumeration of solutions of transcription.

Its implementation is carried out via a dedicated interface allowing interactive exploration of the solutions space, their visualization and local editing, with particular attention to the processing of grace notes and rests.
