SimpleWAVIO
A simple WAV/RIFF I/O library and extensible RIFF parser were developed as a Google Code project licensed under the GPL v.3. Its project page is here.

This library was made to bridge the abstraction gap in Java's audio API between raw bytes and abstract DataLines, Mixers, Sources and Sinks. The pragmatic purpose is to obtain mathematically-usable numerical representations of PCM WAV/RIFF files in the [-1,1] range which is customary in digital signal processing.

SimpleWAVIO utilizes a small extensible RIFF parsing/writing library in the package com.ritolaaudio.simplewavio.files.*. 
RIFF chunks are identified by their position in the package hierarchy.
