41 *
42 * Demonstrates advanced use of the audio capture and recording features.
43 * Multiple perspectives of the same scene are simultaneously rendered to
44 * different sound files.
45 *
46 * A key limitation of the way multiple listeners are implemented is that
47 * only 3D positioning effects are realized for listeners other than the
48 * main LWJGL listener. This means that audio effects such as environment
49 * settings will *not* be heard on any auxiliary listeners, though sound
50 * attenuation will work correctly.
51 *
52 * Multiple listeners as realized here might be used to make AI entities
53 * that can each hear the world from their own perspective.
