//
// 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.
