40 *
41 * Demonstrates advanced use of the audio capture and recording features.
42 * Multiple perspectives of the same scene are simultaneously rendered to
43 * different sound files.
44 *
45 * A key limitation of the way multiple listeners are implemented is that
46 * only 3D positioning effects are realized for listeners other than the
47 * main LWJGL listener. This means that audio effects such as environment
48 * settings will *not* be heard on any auxiliary listeners, though sound
49 * attenuation will work correctly.
50 *
51 * Multiple listeners as realized here might be used to make AI entities
52 * that can each hear the world from their own perspective.
