My thanks to all those really smart people who come up with ways to demonstrate unfathomable concepts in a way that I can kinda understand. Teachers rock.
That's like, the opposite of a singularity. The frequency is simply increasing (without bound mathematically, but actually very limited by physical constraints) as the disk loses energy.
While both might involve a decreasing pitch as they lose energy, the Euler's disk sound is much higher pitched and more like a ringing or whirring noise, while a black hole's sound, if we could hear it, would be a very low-pitched rumble or groan due to the extremely low frequencies involved in its gravitational waves.
It looks interesting, but otherwise it's a bit superfluous. NASA turned an observation (in X-rays) into a sound file and this photographer then turned the sound file into water waves and took a picture of them. He would have gotten a similar picture if he had played some rock music to the water.
For mobile, I wrote it up in a comment a while back. Search for online mp4 to mp3 converter, some will work with a link to the Imgur *video* (not the post), some you may have to download the video and upload to the site. Then there are apps that will let you trim MP3s, so you can have the sound without the expository parts.
My physics Professor explains some of how this works. The best ball bearings are the ones that bounce the longest because they have fewer internal flaws and crystalline deformations because they don't dissipate energy so it all goes into bouncing
The point of the exercise is a sound, but you only need to listen from 7 seconds into the second clip. The rest is just indeed captions for the guy talking, and if you can read the captions, you're not missing anything in the first clip by leaving it muted.
I haven't had the chance to unmute either (at work) but I'm assuming it's a rattle that turns into a tone that rises in pitch until it fades into silence

The sound of a singularity sounds a lot like a Honda accelerating.

Unmute. It's a little unnerving but not inaccurate.

Very similar to how merging black holes "sound". By "sound" I mean: If you turn the gravitational waves into sound waves.

This might interest you. This is what the sound of a black hole looks like.

Do you know how to actually capture the sound from a video or gif and save it as a file that can be a ringtone? I would like to know how to do that.

This is the tail end with a still picture.

VLC Media Player has a built-in converter that can turn an MP4 into an MP3.
Download the video, go to File > Convert > Add > choose file > select the MP3 profile. Easy-peasy.

Audacity is a good wav file editor. I still use Magix from the olden days.

"Proportional to 1 over the square root of the sine of the angle" I'm going to need a pencil and some paper

f ∝ 1/√(sin α), which means for angle α → 0 frequency f → ∞

Since there was a singularity and therefore time dilation I'd say we allow the archaic spelling "span".

"Span" was funnier. I'm still laughing.

You can tell a lot of time has passed between the beginning and end of the video

Time dilation. Happens around singularities.

Works the other way around, time would slow down almost to a complete halt for him but not for us.

This is far more satisfying than the posted video. Sorry OP, but my vote goes to the bouncing ball.

You could try to look up the manufacturer and it's info. It is very unlike to have been retreated, just surface finished.

Nope. The dude is talking over all the cool sound. No point in unmuting

There’s this post about sound, I’ll watch it on mute! …I think I just fell for your joke.

The captions were "Wow" and "Spectacular". I thought they fit perfectly, but apparently people disagreed.

Unmute at 7 seconds into the second part.

lol. I’m at work using my phone for music so I’ll download the video and watch it later.
