33 *
34 * Demonstrates advanced use of the audio capture and recording features.
35 * Multiple perspectives of the same scene are simultaneously rendered to
36 * different sound files.
37 *
38 * A key limitation of the way multiple listeners are implemented is that
39 * only 3D positioning effects are realized for listeners other than the
40 * main LWJGL listener. This means that audio effects such as environment
41 * settings will *not* be heard on any auxiliary listeners, though sound
42 * attenuation will work correctly.
43 *
44 * Multiple listeners as realized here might be used to make AI entities
45 * that can each hear the world from their own perspective.
