  14. Subject: Stereo 16bit Playback
  15.  
  16. Ok, I've got another question.  I'm working with some .WAV files and have
  17. a player that can handle any combinations of Stereo/Mono, 8/16bits, Frequency
  18. except Stereo 16bit.  Stereo 8bit is fine, Mono 16bit is fine but not
  19. Stereo *and* 16bit.  I have very little information on the .WAV file format
  20. apart from a header definition.  It seems that 8 bit samples are signed
  21. and 16 bit samples are unsigned, is this right?  I assume it is
  22. because everything sounds fine to me.  The GUS *is* capable of stereo
  23. 16 bit playback isn't it?  So why does it sound like white noise?
  24.  
  25. I'm setting DMA_16 when I DMA it to the GUS and VC_DATA_TYPE on
  26. playback and I am using two voices for playback (i.e. software control
  27. method).  So what have I done wrong?  There has to be a simple answer to 
  28. this!
