[GreenKeys] Saving RTTY art as audio

[Tim McNerney]

Indeed, storing RTTY art for posterity is a noble cause.
Can you help me understand the rationale behind storing RTTY art
as audio files (MP3s, etc) instead of in binary form?
(i.e. "just the bits, ma'm")
For certain application, especially where there is
a time component, or where one is training RTTY operators
and the like, I can certainly understand the need for audio.
