For more Utah arch vibration content, check out Prof. Jeff Moore's twitter feed @UtahGeohaz (Jeff is in the same department as the link). Here's some very cool visualizations showing exaggerated vibrations of natural wonders: https://twitter.com/UtahGeohaz/status/1451218202621399043 (Colonnade Arch) https://twitter.com/UtahGeohaz/status/1473692964216057865 (The Matterhorn) https://twitter.com/UtahGeohaz/status/147369…

I remember a project that would amplify videos of very subtle movement. I wonder if that sort of tech could be applied here.

I long time ago I had an audio cassette of recordings from, I think it was Voyager, of the ambient interplanetary EM signals it encountered transposed somehow into audio. It was eerie and wonderful, a little like whalesong, and one of the most haunting and beautiful things I've ever heard.

Symphonies of the Planets, perhaps?

Earlier quoted context omitted.

When you visit this arch, there are many signs telling you to treat it with respect as the natives do. They probably just got permission from the tribe to do the recording with the caveat that they treat the arch with similar respect. It's an incredible arch, but one of the harder ones to get to.

It used to be easy to get to. Lake Powell came within a quarter mile of it when I was a kid. When it hit full pool, I think the lake actually extended under the arch. At that time, nobody was particularly concerned with Native American sentiments about the arch. I mean, we didn't do anything that was obviously disrespectful to us, but I don't know how the Native Americans felt about us just walking up to and under it…

That's neat!

Since Lake Powell was formed in 1966, it must have only been for a small number of decades in all of history that the bridge was easy to get to.

going to utah for pycon. this got me stoked up on it

Just a note. Arches is a good 4 hour drive from Salt Lake City. (Not to try and discourage your visit. I'm from Utah and I've often thought of trying to arrange some sort of Python/Data desert or ski outing.)

It's worth renting an SUV in SLC and some camping gear from REI on the way to arches, and driving through to Denver, dropping off the gear at REI and going home on the plane. You could probably even get some skiing in at Arapahoe Basin.

Video magnification -- I've always been surprised that this hasn't been commercialised. Would be valuable in e.g. infant monitors, or as a diagnostic tool in remote video medical consultations.

There's sample code on that site, and an online version linked too:

Is there a name for shifting the recorded phenomena into the part of spectrum where humans can directly sense it? Or for converting signals into different medium, so that we can hear or see signals that we couldn't sense otherwise? I'd like to know the name so that I can hunt for more examples and applications.

A good example is Dwingeloo radio telescope where they convert pulsar signals into audio in realtime so that you can listen to it using headphones. Another example is playing a sound every time your runtime preforms garbage collection, to gain first-hand intuition for internal operation (like you can pick up any abnormalities in the car engine sound).

In case of images, hyperspectral imaging[0] maybe.

NASA, when publishing the Sinister Sounds of the Solar System, called the technique Sonification[1].
