rlm@14 30 /**
rlm@14 31 *
rlm@14 32 * Demonstrates advanced use of the audio capture and recording features.
rlm@14 33 * Multiple perspectives of the same scene are simultaneously rendered to
rlm@14 34 * different sound files.
rlm@14 35 *
rlm@14 36 * A key limitation of the way multiple listeners are implemented is that
rlm@14 37 * only 3D positioning effects are realized for listeners other than the
rlm@14 38 * main LWJGL listener. This means that audio effects such as environment
rlm@14 39 * settings will *not* be heard on any auxiliary listeners, though sound
rlm@14 40 * attenuation will work correctly.
rlm@14 41 *
rlm@14 42 * Multiple listeners as realized here might be used to make AI entities
rlm@14 43 * that can each hear the world from their own perspective.
