Stero channels aren't encoded in the depth and radial axes. They're encoded in the same plane, but rotated 45 degrees, so a mono record player (depth only) plays a balanced sum of each channel.
Edit: mono is radial only, not depth.

- WrtCdEvrydy 5y agoWell, that definitely hurt my brain.
- radomir_cernoch 5y agoWow, the best example of teaching minimalism I know. Even though the website fails on so many levels, ;-) I still get the message in 15 seconds.
- hulitu 5y agoMaybe you are looking at the wrong one ? It loads instantly. I do not have to zoom to read the text. No node.js, cdn and other curses of "modern" web. The only annoying thing is that the guy went to great lenghts to get the audio only to convert it later to mp3. I guess there is no hope. ( it could have been worse - webm).
- jakecopp 5y agoIt reminds my of the Hyperphysics [1] website, which I believe borrows from Apple's Hypercard (pre World World Web) information tech! [1]: http://hyperphysics.phy-astr.gsu.edu/hbase/hframe.html http://hyperphysics.phy-astr.gsu.edu/hbase/hframe.html
- Fnoord 5y agoThis website, as well as the one in the thread's URL, are exactly in the way as I learned the WWW was when I first started using it.
- ngcc_hk 5y agoIt fits its theme ... vinyl
- danmur 5y agoDon't joke, we'll probably see web 4.0 distributed on vinyl soon enough. Just gotta get the assets down to less than 100mb.
- Spare_account 5y agoIs there a Vinyl-ROM format?
- noman-land 5y agoAmazing. Thank you. I immediately saved this, bookmarked it, and shared it with half a dozen people.
- dr_zoidberg 5y agoWhen I read the title I immediately thought of a "laser tip" that and reading the reflections of it, not something based on software that would "read" an an image. Following this animation I'm left thinking that you could do a bit of filtering to better extract the wave(s) from an image, though you'd require a particular setup for the lighting conditions to get the best possible quality out of it. And then back to my first idea: probably a laser-tip would be the best tool here too. Unfortunately I don't have vinyl records around to test any of this!

- karmanGO 5y agoThat is a great explainer, simple and clear. Thanks for posting!
- dehrmann 5y agoI always found this solution to be an incredibly clever and elegant way to encode stereo sound while maintaining backward compatibility.
- globular-toast 5y agoYep. This is one of my favourite engineering solutions of all time, up there with colour TV and UTF-8.
- fortran77 5y agoYes, but it's actually equivalent to "Left - Right" being encoded in the vertical plane and "Left + Right" encoded in the horizontal plane.
- DavidVoid 5y ago> so a mono record player (depth only) You mean horizontal only? Old Edison disc records encoded single-channel audio in the vertical axis (varying the depth), but regular 78s and single-channel vinyl records encode the audio in the horizontal axis.
- kevin_thibedeau 5y agoEdison diamond discs use the bottom of the groove rather than the walls.
