What spacecraft sound like Options

[djellison]

Random thought. I was just sent an interesting movie, which was a composite of various space stills, with some plasma/wave sounds in the background and a generic 'beep beep' spacecraft noise on top.

But what do spacecraft actually sound like when transmitting - has anyone heard the 'feed' from a DSN dish be deconstructed into an audible wav? Is it like a dial up modem or something else. Do spacecraft at 288kbps sound different to those at 120bps etc? I'm not talking about the spooky interpretations of mag/fields/waves/particles etc that we are treated to - but the actual downlink itself. The only example I can think of is the MEX cannister mode listening to PHX during EDL - but that actually ended up like a plasma/wave observation because of the massive doppler involved!

I remember the BBC 'The Planets' series ( very good, spectacular visuals, but now very out-dated ) - and every time a spacecraft flew past the camera, it made a beautifully doppler shifted 'beep beep beep' sound.
