    abstract = {Drum samples are an important ingredient for many styles of music. 
                Large libraries of drum sounds are readily available. However, their 
                value is limited by the ways in which users can explore them to 
                retrieve sounds. The available schemes for organizations those collections 
                are either insufficient to hold a large number of samples, rely on cumbersome 
                manual classification, are inconsistent, and error-prone.
                In this paper, we present a new approach for automatically structuring 
                and visualizing large sample libraries using only audio input. We create 
                a hierarchical user interface for efficient exploration and retrieval 
                which is based on a similarity measure for drum sounds and 
                self-organizing maps. },
