phat.server.microphone.TestAdvancedAudio

All Implemented Interfaces:

com.jme3.system.SystemListener

public class TestAdvancedAudio
extends com.jme3.app.SimpleApplication

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

Method Detail

main

public static void main(String[] args)

You will see three grey cubes, a blue sphere, and a path which circles each cube. The blue sphere is generating a constant monotone sound as it moves along the track. Each cube is listening for sound; when a cube hears sound whose intensity is greater than a certain threshold, it changes its color from grey to green. Each cube is also saving whatever it hears to a file. The scene from the perspective of the viewer is also saved to a video file. When you listen to each of the sound files alongside the video, the sound will get louder when the sphere approaches the cube that generated that sound file. This shows that each listener is hearing the world from its own perspective.
