37 /**
38 *
39 * Demonstrates advanced use of the audio capture and recording features.
40 * Multiple perspectives of the same scene are simultaneously rendered to
41 * different sound files.
42 *
43 * A key limitation of the way multiple listeners are implemented is that
44 * only 3D positioning effects are realized for listeners other than the
45 * main LWJGL listener. This means that audio effects such as environment
46 * settings will *not* be heard on any auxiliary listeners, though sound
47 * attenuation will work correctly.
48 *
49 * Multiple listeners as realized here might be used to make AI entities
50 * that can each hear the world from their own perspective.
