RIFF-WAVE Config:

  The RIFF-WAVE player works by loading a  sample  bit  by  bit  (buffer by
  buffer)  and  play  it. As user you can define how big each buffer should
  be and how much memory that should be used at maximum.

  Load buffer size in Kb: The size of each load buffer. Please note that if
  you want a buffer size of e.g. 64 Kb and you try to load a 20 Kb  sample,
  then  the  player  will  allocate  a 64 Kb buffer. That is, no matter how
  small or large your sample is, only whole buffers will be allocated. e.g.
  a 75 Kb sample will need for instance two 64 Kb buffers.

  Note1: If you play stereo samples the buffer size will be doubled.

  Max memory to use in Kb: The maximum amount of memory to be used for load
  buffers. This number should at least be six times the size  of  the  load
  buffer size (because of double buffering and stereo). If you haven't  got
  enough  free  memory to allocate 6 times the size of the load buffer, the
  playback of the sample can get corrupted.

  Obs: If your harddisk have problems keeping up with  loading  the  sample
  buffers, it might help to increase the buffer size.

  Play only once: This  will tell APlayer only to  play the sample once, no
  matter how big it is.
