audioDB is a feature vector database management system for content-based multimedia retrieval.

Interaction to the database management system at present is through a command-line database client for general use, and through a SOAP server for queries; development of an API is almost complete as of December 2008. mHashup provides a user-friendly front-end to audioDB for particular use-cases, while there is in addition a prototype graphical front-end exposing more of the low-level functionality.
