All Implemented Interfaces:
MusicService
public class EffectsMusicService extends Object implements MusicService
A MusicService that handles playback for short (less than or equal to 5s) sound effects that are played from memory. All files must be in the WAV format to ensure consistent playback. There is no limit on the number of sound effects that can be loaded, but loading too many will cause performance issues, so please be judicious.
