Basically I am just playing around with file types to see if I cannot find one that will work for everyone.
I started using the MP3 because that's what the fellahs down in Melbourne needed from my end.
I then tried the M4A file type and the MP4 file type.
This is a WAV file type and it's a considerably larger file, for whatever reason.
In any case, it works on my system.
Does it work on yours?
