Marsyas Submissions to Mirex 2009

Marsyas is an open source software framework for audio analysis, synthesis and retrieval with specific emphasis on Music Information Retrieval. It is developed by an international team of programmers and researchers led by George Tzanetakis. In MIREX 2009 the Marsyas team participated in the following tasks: Audio Classical Composer Identification, Audio Genre Classification (Latin and Mixed), Audio Music Mood Classification, Audio Beat Tracking, Audio Onset Detection, Audio Music Similarity and Retrieval and Audio Tagging Tasks. In this abstract we describe the specific algorithmic details of our submission and provide information about how researchers can use our system using the MIREX input/output conventions on their own datasets. Also some comments on the results are provided especially highlighting the excellent running time performance of our system (an order of magnitude faster than any other submission while remaining competitive in task performance).
