We've taken ten seconds of data from the Arecibo telescope
and converted it to sound.
The original data is around 1.42 GigaHertz (billion cycles/second),
which is way too high to hear.
We've extracted a 10 KHz band
and shifted it down to the audible 0-10KHz range.
Expect to hear a hissing sound. That's how radio signals from space generally sound. The type of signal SETI@home is searching for would sound like a whistle. It would probably be too faint to hear (although SETI@home could hopefully detect it).
