 The noise in the OP link does not sound like white noise. I am no doubt being unnecessarily pedantic here, but white noise is a random signal with a constant power spectral density - i.e. all frequencies are equally produced. The example has a lot of predominantly low frequencies.

There is also pink, brown/red and grey noise, each with its own spectral properties.

Whatever the source of the original noise (and it could be generated by many electronic devices, not necessarily signals received from space) is does sound 'spooky' if you listen to it for long enough!

I admit to being uncomfortable in using random noise from any source to 'evoke' EVP as it simply leaves the door wide open for auditory pareidolia - something we should be aware of in this field.
