rlm@41 38 *
rlm@56 39 * Demonstrates advanced use of the audio capture and recording
rlm@56 40 * features. Multiple perspectives of the same scene are
rlm@56 41 * simultaneously rendered to different sound files.
rlm@41 42 *
rlm@56 43 * A key limitation of the way multiple listeners are implemented is
rlm@56 44 * that only 3D positioning effects are realized for listeners other
rlm@56 45 * than the main LWJGL listener. This means that audio effects such
rlm@56 46 * as environment settings will *not* be heard on any auxiliary
rlm@56 47 * listeners, though sound attenuation will work correctly.
rlm@41 48 *
rlm@56 49 * Multiple listeners as realized here might be used to make AI
rlm@56 50 * entities that can each hear the world from their own perspective.
