This is a work in progress so the documentation is still fairly basic at this point.

You can grab all the necessary files over in the file section.
And the hardware schematic in the Hardware Details section.

The Wav2Header python script is very simple, you can get help with the --help flag on the command line

H:\GitHub\Wav2Header>c:\Python26\python.exe --help
Usage: [options]

  -h, --help            show this help message and exit
  -f WAVFILE, --file=WAVFILE
                        Specify Wav file for conversion
  -q QUALITY, --quality=QUALITY
                        Specify quality conversion 1=High, 2=Med, 3=Low
  -s SAMPLE, --sample=SAMPLE
                        Optional sample override for more specific conversion
                        Specify output header file
  -l LENGTH, --length=LENGTH
                        Optional Length Limit in bytes to keep the header file
                        from being to big

Here is an example converting a wav file into a .h header file using a quality setting of Medium:
H:\GitHub\Wav2Header>c:\Python26\python.exe -f g:\temp\meow.wav -q 2 -o C:\devl\pic\wavPlayer\meow.h

               Wav To Header File Conversion
                    Version: 1.0.0

Converting wav to header....
Header Bytes: 4464
Use a delay time of approx. 180 us @ 64Mhz
Conversion complete!

Refer to the example code in the file section to see how to use the generated .h file.
