Dial Up Modem Handshake Sound - Spectrogram

So sound is 4 dimensional?

I can't remember if my first modem was a 1,200 or 2,400 bit/s, but I'm pretty sure my first bbs was Prodigy around 1988. I also remembered my first hdd was a $400 40mb beast, lol. Possibly Hewlett Packard 😂
Now we have microsd cards up to 1.5tb for under $150. It would take 3,750 of my original hdd and would have cost $15,000,000 🤣

So cool

Remember, every bump of the purple bits is potentially a bit (or more!) of data. It sounds like white noise because it is using as much of the spectrum as the wires between the computers will allow. All the different sounds are each modem trying different techniques and speeds and asking the other side to confirm reception in order to find the best style and speed. On really crappy phone connections, it will still manage to work with lower quality methods, but on really nice connections, it will be able to use the high quality methods. This process is how it figures that out.

Eventually once the modems are satisfied that they have figured out the best options, they turn off the speaker. (You could actually set modems to not turn off, and they'd blare that staticky sound the whole time. Or you could set them to be quiet the whole time. The reason they defaulted to you hearing the first few seconds is so you could clearly hear if you got a person, wrong number recording, fax machine, busy signal, etc. instead of the computer you were expecting.)

I wonder what gigabit internet would sound like ??

Anyone remember MIRC chat?
😊

Sound of my childhood. Another one would be c64 booting up from a tape.

When you tried to call home but Mom was playing POGO games online

you can actually communicate with a computer like this if you know the number and reproduce the sounds one to one and decode the sounds in milliseconds

Nice.

Nobody talking about how this video was looped perfectly

0.25x sounds familiar.

AOL: Welcome

Also AOL: You got mail

Welcome to the Information Superhighway.

Why did we even hear this out of curiosity?

what baud?

When 56k was the big next thing

my brain during the exam

I think I speak for all of us when I say probing/ranging is the best part.

im surprised how you managed to make a video about the dial up sound be pretentious

Took me back a lot!

We’re living in The Matrix™️

neat

Oof, that didn't sound like a healthy handshake, sounds like it connected far lower than 56k

God I miss this sound

and then we looked up "boobies"

oh hey I've played this Mario level

My humor is so broken, as soon as the graph almost filled completely I started laughing like it was one of those sorting algorithms

I wonder if this was done on a 56k baud modem. If so is that why it the frequency spectrum spikes around the 5khz to 6khz area? Does the frequency range of sound when the computers are communicating effect the speed acting as extra lanes per band?

this video is the only non-shorts video i know with a perfect loop

Man I don't miss this sound....

wtf am I lookin at 3am?

Why can't we hear today's computer communication? Sorry if that's a dumb question. Gotta ask

Been there... ❤

me during any test in school:

YOU GOT MAIL.

omg

Fun fact: after a while, we were able to build dial-up modems that were silent. People didn't like that however, as they thought they weren't working right. So, new ones were built with a speaker that emulated these sounds.

I should really go to bed

I had 33.6Kbps in 1997 pc ISA card… 😇

If she doesn't recognize these sounds, she's too young for you.

Ох, какое рукопожатие хорошее, мужское, богатырское.

And apparently the somehow turned into a webpage

Beautiful

“Welcome.”

“You’ve got mail!”

Holy shit, I never knew PCs did drugs before.
