rlm@14 43 /**
rlm@14 44 *
rlm@14 45 * Demonstrates advanced use of the audio capture and recording features.
rlm@14 46 * Multiple perspectives of the same scene are simultaneously rendered to
rlm@14 47 * different sound files.
rlm@14 48 *
rlm@14 49 * A key limitation of the way multiple listeners are implemented is that
rlm@14 50 * only 3D positioning effects are realized for listeners other than the
rlm@14 51 * main LWJGL listener. This means that audio effects such as environment
rlm@14 52 * settings will *not* be heard on any auxiliary listeners, though sound
rlm@14 53 * attenuation will work correctly.
rlm@14 54 *
rlm@14 55 * Multiple listeners as realized here might be used to make AI entities
rlm@14 56 * that can each hear the world from their own perspective.
