Fast Visual Music Discovery Via Locality-Sensitive Hashing

mHashup is a novel visual interface to large music collections, such as today’s million-song download services, for discovering musical relationships among tracks. Users engage in direct on-screen query and retrieval of music fragments in an instantaneous feedback flow performed by a locality sensitive hash table in secondary storage.

mHashup facilitates both professional music searches (such as musicologists and copyright lawyers seeking the origins of sampled music with location markers precisely given for each returned track) and end-user music applications (such as discovery of “dark media” by its relationship to known “hot” items). The visual/auditory display of results incorporates summaries of retrieved tracks and facilitates a user-interaction feedback cycle for refining and expanding music discovery processes. mHashup’s visual interface uses the core functionality of a content-based search engine as a visual grammar to be explored by direct manipulation.
