Jipes

Jipes is an open source library that allows you to efficiently compute audio features. Possible uses for these features are general music information retrieval (MIR) applications. Jipes attempts to avoid duplication of work, by applying some simple optimizations. It focuses on features instead of the raw, untyped signal streams; it supports rich types to be used, where other frameworks only offer arrays of raw data. Also, by using Java generics, many core interfaces and classes can be typed to whatever class you see fit for the purpose. In Jipes, signal processors connected to each other, form so called pipelines. To support abstract and better handling of long processor chains, these pipelines arent just called pipelines, there is also a real pipeline class. It lets you create pipelines you can handle just like a regular, single signal processor (Composite pattern).
