  30. But PCM is a different technique; it might suggest to some marketroid a 
  31. number to shoot for, but not much else.
  32.  
  33. 48.0 is the standard pro sampling rate used before and since.  When Phillips
  34. announced their format, soon thereafter I remember a Sony digital processor
  35. vaporware announcement about dual rate capability, etc.
