Onset_Leveau is a smal annotated database for Onset detection that was in particular used for MIREX 2005 onset detection task.
Details concerning this database are given in the following paper:
[pdf] P. Leveau, L. Daudet et G. Richard ,”Methodology and Tools for the evaluation of automatic onset detection algorithms in music”, International Symposium on Music Information Retrieval (ISMIR), Barcelone, Espagne, oct 2004.
The database is proposed with two labels sets: “goodlabels.zip” contains labels that have been validated by the 3 annotators but may miss some that are difficult to annotate precisely, and “labelsPL.zip” contains the onsets annotated by only one annotator.
The database can be downloaded with the annotation software from the following page:
