/**
 * FIXME:
 * specify the buffer size in the open(AudioFormat,int) method. A delay of 10ms-100ms will be acceptable for realtime audio. Very low latencies like will 
 * not work on all computer systems, and 100ms or more will probably be annoying for your users. A good tradeoff is, e.g. 50ms. For your audio format, 
 * 8-bit, mono at 44100Hz, a good buffer size is 2200 bytes, which is almost 50ms
