[GreenKeys] RTTY ART?

[Eugene Hertz]

Stan, I've often thought about just this thing.  I am in the process of having a program written that will convert ascii text to 5-bit ITA5, with whatever mark, space frequencies and speed into .wav files (Eventually .mp3). Think of a program that would take the form like this:

c:\> txt2afsk.exe -input=file.txt -ouput=afsk-file.wav -mark=2125 -space=2295 -speed=45.45

you get the idea. This will create the afsk file in any given shift and speed very quickly without having to wait for a half-hour rtty art file to convert by running it through a TU to generate the tones, or otherwise.

I might have a prototype in the next few weeks.
Eugene
