It's fascinating, but you would think that with four minutes to play
with they could spend a few seconds explaining that it's _not_ sound,
but audio-frequency radio rather like the Rugby time signal
transmission.

I remember being delighted by similar recordings made by Voyager at
Jupiter that were played during a "Horizon" programme in the early
1980s.

You can find more of Don Gurnett's recordings at
http://www-pw.physics.uiowa.edu/space-audio/sounds/ and some ESA
recordings at http://www.esa.int/esaSC/SEMLAJWO4HD_sensations_0.html
A web search for "sounds from space" will keep you busy for days!
Thanks.
