//              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.
