Youtube video about the sound of a pulsar

[Garlic]

Hello PF,
I found this youtube video about the sound of a pulsar, and I have been wondering if this sound is really the radio signals of a pulsar converted into sound, or something fake.
Thank you

I think it is fake.

It seems to be an accurate sound based on this Vela Pulsar soundfile from the CSIRO Parkes Observatory in Australia.
