+  Audio Data Input Base Class
+  by Gary P. Scavone, 1999-2000
+
+  This class can handle multi-channel
+  input.  Multi-channel input is
+  interleaved in the vector "data".
+  Actual data input occurs in the
+  subclasses of WvIn.
+
+  Currently, STK is only supporting a few data
+  types (16-bit integer .snd, .wav, .raw, and
+  .aif files and 64-bit double MAT-files).  In
+  order to support more formats AND to make the
+  writing of subclasses easier, a format ENUM
+  could be defined and a generalized getData()
+  function written within this WvIn class.  Then,
+  most subclasses of WvIn would only have to
+  setup the appropriate parameters and all
+  other processing would happen here.
