rlm@41 39 /**
rlm@41 40 *
rlm@41 41 * Demonstrates advanced use of the audio capture and recording features.
rlm@41 42 * Multiple perspectives of the same scene are simultaneously rendered to
rlm@41 43 * different sound files.
rlm@41 44 *
rlm@41 45 * A key limitation of the way multiple listeners are implemented is that
rlm@41 46 * only 3D positioning effects are realized for listeners other than the
rlm@41 47 * main LWJGL listener. This means that audio effects such as environment
rlm@41 48 * settings will *not* be heard on any auxiliary listeners, though sound
rlm@41 49 * attenuation will work correctly.
rlm@41 50 *
rlm@41 51 * Multiple listeners as realized here might be used to make AI entities
rlm@41 52 * that can each hear the world from their own perspective.
