AudioDB

What is AudioDB ?

AudioDB is a feature vector database management system that is optimized for passage-level retrieval from very large collections (1M+ tracks). It supports sequence-of-vectors searching on large databases. Developed by Michael Casey and Christophe Rhodes as part of Goldsmiths' OMRAS2 development.

Features:

• Exhaustively search for matching feature sequences across tracks
• Scales to searching over millions of tracks in milliseconds
• Locality-sensitive hashing (LSH) indexing and retrieval engine
• Automatic LSH parameter estimation for optimal performance
• Search high-dimensional vector sequences
• Efficient nearest-neighbour reporting of LSH results
• Command-line and Web services interfaces (over SOAP)
• Library and C API for developers
• Result format supports arbitrary primary key formats (e.g. URI, RDF)
