Released under the open source GPL+CE (Classpath Exception) License.

You can use this wrapper with the free OpenAL Soft implementation found in The OpenAL Soft Homepage The above page includes a source package, as well as pre-compiled win32 dll.

The library enables you to easily integrate true 3D surround sound into your applications. It supports stereo 3D sound, quadraphonic (4-speaker) configuration, 5.1 and 7.1 surround speaker configurations.

Example Code:

The following code shows how to load and play a simple wave file:

Basic example - Load and play a wave file

OpenAL openal = new OpenAL();
Source source = openal.createSource(new File("sample.wav"));
source.play();

Advanced example - Set source parameters

source.setGain(0.75f); 		// 75% volume
source.setPitch(0.85f); 	// 85% of the original pitch
source.setPosition(-1, 0, 0); // -1 means 1 unit to the left
source.setLooping(true); 	// Loop the sound effect
Thread.sleep(10000);     	// Wait for 10 seconds

Finally, clean up

source.close();
openal.close();

You can create multiple sources and play them simultaneously. You can also change any of the source parameters while the source is playing.
