Sound of a flare?

It seems that the Cassini spacecraft which is currently about 240 days away from Saturn managed to record the 'sound' of one of the latest solar flares as it went past the probe. The 'sounds' are actually radio waves produced by electrons moving out of the flare and so take only 69 minutes to reach Cassini which is 8.7 times further from the Sun than the Earth.
