/** A performance oriented implementation of the {@link AndroidAudio} interface.
 * 
 * Sounds are played on a separate thread. This avoids waiting for sound ids on methods that can 
 * potentially lock main thread for considerable amount of time, especially when playing several
 * sounds at the same time. The limitation of this approach is that methods that require a sound id
 * are not supported.
