// Project:     CMod S6 System on a Chip, ZipCPU demonstration project
//
//
// Purpose:     
// Purpose:     This program converts an 8kHz, 16t, mono- sound data file into
 
//              samples that can be read and understood by the C compiler and
 
//      hence included in a S6SoC project as the ``doorbell'' audio sound.
 
//
 
//      To use this, first convert your sound file to 8kHz, 16t, raw mono
 
//      format.  The sox utility works well for this purpose.
 
//
 
//      Then, run this program wih the single argument being the name of that
 
//      sound file.   The standard output will be the resulting C-code 
 
//      representing/recreating that sound file.  Pipe this into a file for
 
//      inclusion in your program.  You can then reference both the number of
 
//      samples from that file, as well as the number of words those samples
 
//      are stored in, as well as what those samples are.
 
//
 
//      The samples themselves can then be placed in a flash partition, and
 
//      read like any memory from within your program.
