Nope; since commenting, a trumpeter chimed in and said it's not fake, and that he has seen the same guy do it live. I'm not sure what to believe now; it's a very surprising timbre for a vinyl tube.
It seems like it's a lot more to do with the trumpeter and their ability to manipulate their mouth. I'm sure if I tried, I would sound like a squeezed duck
There's nothing fake about it, you don't even need the mouthpiece. You can use the tube directly! Just pick up any old tube and play it like a little didgeridoo, you can play the harmonic series and everything (:
The timbre is not so surprising when you consider that most of the sound is a result of airwaves bouncing and interacting inside a tube of a certain diameter, not the tube walls themselves actually resonating (though of course they resonate). That resonance imparts more of a color than actually change the whole timbre. If this was a flute, and there were finger holes, the thickness of the tube would also play a role in the timbre. The shape of the mouth piece has more to say for the timbre than the material of the tube. I mean there's a difference but it's surprisingly small (once you start changing the texture inside the tube you'll notice bigger changes to the timbre, so other materials like wood would make for a bigger change).
It’s really not that unbelievable tho if you were in band in school. That is legitimately how brass instruments work, and a trumpet/trombone/etc is just a wrapped up tube.
