Forget the technical arguments, compare that "call" with those on:

It's the same sort of sound as a male pheasant showing off to a female by
wing flapping and I've got lots of those.

My original guess was that the recording was enhanced out of sight, so I
equalised the power spectrum to a more normal profile and got very distant=

grouse wing noises and some "reverb".

To answer the original question - I can hear it on headphones but not on my=

laptop speakers. The frequency is just too low to get through.
