JRtAudio

JRtAudio is a Java wrapper around the real-time audio library RtAudio. You can use JRtAudio to easily access audio hardware from your java program.

To start, download the code from the svn repository, and refer to the readme included in the distribution. Some basic examples are also included in the repository.

For audio applications that require features such as loading and saving audio files, applying filters, etc., I would recommend using Beads instead of JRtAudio.
