AbstractMusic master classes contain a lot of pedagogically valuable information that is worthy of preservation. One way to do it is to record these master classes and store this audiovisual material for a later consultation. In order to improve the access to all this data, it is necessary to label the recordings with editorial meta data, including information as the teacher, instrument and pieces played. It is also important to locate the most pedagogically relevant excerpts within the master classes in order to provide an easy and direct access to these excerpts. There is finally the need to establish taxonomies to classify the different explained concepts. Manual annotation is a very laborious and time-consuming task. It is then necessary to develop a technology intended to assist the annotation and classification of the audiovisual material. This paper presents a system intended to ease manual annotation of sound archives. In a first phase, the system performs an automatic segmentation of the recording according to its timber. This first stage allows identifying for instance when the teacher is giving some explanation or when the student is playing. In a second step, the system identifies a set of pedagogically meaningful segments. In order to characterize what a pedagogically meaningful segment is, the system is trained with a set of manually labeled recordings by expert users.
