I love how the end of the transmission just seems to be a collective scream of celebration from both computers😂
This comment made me appreciate the sound way more, hah!
was thinking that, like it's a collective victory screech from SpongeBob lol
Sounds kinda like applause lol
ULLA!
Yay!
So it's a really odd sounding conversation between machines?
Calling modem: Hey, just wanted to call you about the internet.
Receiving modem: Yeah, sure.
Calling modem: Cool.
Receiving modem: Want a modulation method?
Calling modem: I accept. So which standard should I use?
Receiving modem: Here what you've got: *insert standard*.
Calling modem: OK.
Receiving modem: Man do I HATE echo suppressors!
Calling modem: Yeah, me too! A lot! Like so much! I despise them! So very much! THEY SUCK! (This is it playing 6 times) Anyway, these are my standards and PTSN *insert both here*.
Receiving modem: My standards and PTSN are... I say, mine are... I REPEAT, mine are... *insert here*.
Calling modem: You like this frequency?
Receiving modem: You like this one?
Calling modem: How's this one?
Receiving modem: OK, so we've got *insert bit rate here* and *insert modulation rate here*. So in 3... 2...1... we sync our minds!
Calling modem: Yeah, ok... 3...2...1...
Both modems: Max phone line speed achieved! We did it! We are online! We are one mind!
its actually mostly AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAHHHHHHHHHHHHHHHHHHHHHHHHHHHHHSSSSSSSSSSSSSSSSSSSSSSSSSSHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH

Same

@@mashikawa1995 same I heard it from fake disaster warnings online
I heard it in my dream and in that dream the screen of the thing was a bunch of little people walking.
yeah, always used to scare me as a kid
I didn't grow up with this and I am really amazed at how much is behind these sounds. I think, as a computer nerd, I really missed out on something, as this is basically communication between two devices turned into sounds, which these days aren't heard anymore
yeah we humans pretty much let machines talk in private now...
Imagine throwing a handful of pots and pans down the stairs at 2am because you wanted to check your messages. The sound is neat. It's nostalgic for me and many others. But you didn't miss anything. What we have nowadays is much, much more efficient, and thankfully, silent ☺
If the insultation of your PC is horrible you can still somewhat hear it, if you're lucky. Once heard USB data transmission through my 3.5mm Jack headphones because there was so much intereference.
yo same
Start learning about Wi-Fi and Ethernet protocols. Even though we can hear them they are just as well engineered and designed as what is in this video. Very clever people a lot smarter than me design things we use every day

Evan Perrine how
I remember when I was really really little, and my dad would go online every night for his fishing club website. I had no clue what that sound was, but I was fascinated by it. For seeming like such a primitive thing right now, its actually pretty amazing how complicated that sound really is.
I accidentally called a modem today and my phone's volume was all the way up so you could imagine the pain my ears were experiencing
CamChild :/
O__O ????
Pocoraven,
You dial a number on you phone.
717-664-3735 no longer works
Try these:
778-379-7158
503-852-3170
The above numbers dial to modems, when a modem picks up it expects a tone from another modem trying to connect.
If you call the above numbers the modem cannot connect because you are not a modem.
If you want to, you can go to

Jack Nedry why does it sound different?
Unless you called a fax, all you'd hear is a repeating BEEP because it can't make a connection
Ok, that's oddly really cute how they're basically just negotiating and agreeing on how they should internet.
You could have bullshitted this whole video and i wouldn't know. Thats how much i know about this stuff lol. Great video!
I'm here at 69 likes. noice :)
@NEPA Buses They did - but they were just missing or slightly off content, nothing to the point where the video is false or fake
Was born in 1999 and never had dial up so it was always a bit mythical to me, very interesting to learn that these sounds actually mean something
Sux
Same here. I get nostalgia from this world I've never lived in.
This modulation technique in its original state is still being used today by military, police, aircraft, marine to send and receive small bits of important or critical data over analog FM/AM radio sometimes on distances over thousands miles like in the middle of ocean. I am HAM/SDR radio hobbyist and I can hear it on both AM and narrow band FM commonly on police and aircraft frequencies. They also use morse code time to time which is funny, presumably when there's not enough bandwidth or signal is weak.
I see a fellow ham/sdr radio enjoyer?
When I was younger, I used to be terrified of the sound because I thought my computer was about to explode
Yall being scared of the modem as a kid made me remember that when there was a blackout our modem would dial up automatically the moment the power came back. That shit was scary because you never expected it
But why could we hear the sounds? Why did they have to be audible?
Yes, you could also get a hint at failure causes, from the sound of TRYING to connect and failing.
Who says it "has to be" audible? +++ATM0
I had a phone line with a hum; I could listen to the sounds, and tell if I needed to redial to attempt to get a higher speed.
Mass mind control
audio sound where commands. So you could bypass a phonebooth by whistling in the phone to make free calls on a land line.
This is actually v cool. It's pretty cool to see how we struggled before, and how today's technology makes things much easier and accessible
What do you mean “v” cool?
@@elytrous4898 contraction of "very" i believe

6:56 "This is your data. This is what you came to the internet for whether it be text... or text" I LOL'd.
Excellent explanation. That sound brings back so many memories, especially of anxious moments waiting for the final confirmation that a stable connection had been established and my queued email would now be sent.
It only occurred to me when you explained what a dial-tone is that many of the latest generation would have no idea what that is.
I used to be able to know whether or not my internet connection would be successful based on how the dial-up sounded from beginning to end....now this has confirmed my suspicions that those sounds and patterns were actually meaningful.
The Dialup sound isnt Infamous, It's nostalgic.
butt dickenz It's both..
LOL so right!
It's infamous because it's nostalgic
She's boff***
Makes me want to ditch my cable modem and get dial up. As an added benefit I would also be spending less time online.
Man I remember the old times when I was on the internet and my mom had to use the phone to call someone so I had to get offline 😑
If my dad was on call for work none of us could use the internet 😐
After 23 years FINALLY someone explained the greatest mystery sound of my childhood! Thank you so much!
I remember when I was younger I usted to get really sacred of the dial up sound. I muted the speakers because I sometimes didn’t want to hear it. This one time I decided to connect on a dark, rainy afternoon and the speakers were on, gosh I was soo scared I almost died lol
yeah its a ghost sound 2001 vibes omygosh
Same!
If you look at the numbers being dialed at the beginning you can see that each one is made of two distinct frequencies played on top of each other. There's three different frequencies for the columns on the touchstone keypad and four different frequencies for the rows, when you press a button on a touchstone phone it plays the note for the row and the column. The pound sign and the star were added to the dial pad because they'd already decided to include zeros in phone numbers and the 3x4 grid would give you 12 options, so they just added two arbitrary symbols.
"the pound sign and the star"
Bro they are called hash and asterisk lol

I know some of you have been waiting for me to post a new video, since my audience pretty much octupled at this point. The problem is I was a dumbass and spilled water all over my laptop. It's gonna cost about $500 to fix, so it's best for me just to get a new computer altogether, and if at all possible, transfer the data on my hard drive from computer to computer. Sry bout the wait.
Love the Fire N Ice music :D
Could you do a video on noises modems could make if a snafu occurs? Or, in simple terms, what happens if something goes wrong with the modems?
You should check out this page, this guy did a bunch of testing of different modems and occasionally things went flakey and you can hear the modems trying to chat it out. "I DON'T WANT TO FIGHT. I WANT TO WORK THIS OUT. THIS RELATIONSHIP IS SUPPOSED TO WORK!" goughlui.com/legacy/soundofmodems/
Thanks, I'll look into it when I'm more awake.
The Sacred Gamer A. S. S s
I was always curious why it made those specific sounds no matter who's PC you were connecting with. Thanks for explaining it to me!
Kids these days will never understand the fights between parents and kids over them wanting to make a phone call and having to disconnect and then reconnect
God that scared me so much as a kid. And I remember going on the internet late at night and smothering it with a pillow to quiet it down lol.
You do know there is a volume button on all modems and you can just mute all this?
@@Argantonis you didnt know* would be more better because he is talking about past modems are not uaes anymore.
@@gta6wontreleasesoz887 sme people still use dial up (e.g. rural places
He sounds like the guy that designed the system or something.
At the 5 minute mark on the dot you talk about "The probing segment". What I would find even more interesting is discussing the differences between a 56K modem and earlier modems. This is obviously a 56K modem. The earlier modems didn't have that "Probing segment" or what I call the "Dong Dong Segment" If you followed modems through their history of progression as I've lived through you will know that with each modem series, 300, 1200, 2400, 9600, 14400, 28800, 33600 and 56K, each one along the way added and subtracted things to the overall handshake sounds. 2400 was really short in comparison to 56K. For historical purposes, I think it would be even more informative to discuss the various modem speeds throughout history and their own individual handshaking. Good job and very informative on the 56K modem, but would be nice to see the others as well.

Aol omg blast from the past kids have no idea the struggle us 90s kids had brings back memories
Do you always talk in super-fast sentence fragments?
Daniel Hetrick Yeah, rampant retardation is a part of the “90’s kid” syndrome.
I was listening to FSK tones back in the 1970s when I was an Electronics Tech in the U.S. Navy--I worked on all sorts of things from LORAN A, B, and C (early location triangulation via radio signals), RTT (Radio Telegraph and Telephone - aka Morse Code and voice comms), RTTY (Radio Teletype, 5-bit), Radio Facsimile (aka a fax machine over radio), satellite comms, satellite navigation (we were just putting up the first GPS satellites then), RADAR (stands for RAdio Detection And Ranging), inertial navigation systems, infrared devices, and more. While some of you younger ones think spread spectrum frequency hopping is something new (the basis for cell phones, wi-fi, and bluetooth), the technology was actually co-invented by actress Hedy Lamarr and composer George Antheil, who received a patent on it back in 1942.
Btw, I was born back in the 1950s. ;)
We're starting to sound like old folks.
This is impressive. And you now have 90 subscribers

V8 bis thing
I used to be able to tell if it wasn’t going to work by the sound it made… which was 99.9%of the time. I always thought/imagined it sounded like they were arguing back and forth before saying fuck it- and either giving up and leaving. or murdering each other…depending on the day and how the argument ended.
This confirms it.. they were arguing…..
The dabs of humour make this such a great video and very easy to digest. Thanks!
That always scared me as a kid. Even though I was a mid- 2000’s kid, I got many hand-me-downs from my older siblings. Whenever my grandpa connected to the internet, I had to stand in the other room and cover my ears. That sound still scares me to this day.
As someone who was born pretty much when dial up started to become irrelevant, I find this very interesting. It's cool that you could hear computers literally talking to each other. It makes me wish modern internet devices had some kind of way to make the data they send and receive audible.
If you have a HackRF and tune into somewhere in the 2.4GHz range, you'll eventually come across the channel you're connected to, and will actually be able to "hear" the data that's being transmitted and received (depending on which demodulation method you use (AM, FM, RAW), it'll sound different). I put "hear" in quotes because 20MHz of bandwidth is way outside of audible range.
When I was a kid I thought this was just some sound AOL made up (unique to AOL) to tell humans that the Internet was connecting. I don’t know why I thought anyone would program such a horrific sound for a simple informational message. Of course now I understand that this was computers doing INTENSE NEGOTIATIONS!!!!
This is a 10/10 video.
Very direct, covers just enough background and history, and gives you a occasional laugh.
Thanks!
I'm old enough to remember when the phone line did not have echo suppression and you literally heard every word you said repeated back about a second delay from the time you speak it depending on how far you were if you were hundreds or thousands of miles from the other person there would be a longer delay and in the first days of satellite when the phone companies would bounce the signal off the satellite the delay would be quite significant about 3 to 5 seconds delay between the time you said it and the time you heard it back and it was truly annoying and made it very hard to talk without getting distracted
As far as I remember it was still happening in some parts of the country in the early '80s
I love how the fuzzy part at the end looks exactly how it sounds
Dear Sacred Gamer. You are awesome. I listened to this too many times to count in the olden days, and it's satisfying to hear what it all was. Thank you.
I like it when the receiving modem is deciding on a final bit rate and final modulation rate, best part of the song.
I became quite familiar with a lot of the sounds during the connection process, so it's interesting to learn what each of the sounds actually represent. 😊👍
Very, very good video. I did this stuff at uni for my degree and you've done a fantastic job. DSL doesn't give average users the same ability to visualise what's going on since we never hear, see or touch it! But dial up allowed users to sense it via sound and analyse it easily. Essentially it's all the same thing though, just faster frequencies now that sound much more high pitched when you do get a chance to convert the signal to sound!
These sounds is what I tell people I think animals sound like, we can’t understand what they say, but in reality is a highly complex form of communication
this is a lot more interesting than I thought it would be....
idk why I'm here
Something about the sound terrified me as a child...always felt as if something was physically coming through the line and would come out through our family PC... some sort of digital monster trying to rip its way into reality.
I like when young ppl explain old ppl stuff
Its not even that old, its only about 20yrs old
30 years, and yes that’s pretty old as most people that remember this are probably in their 40’s/50’s now lol
@@EternalNico1 I'm 28 and remember using the internet at my friend's house with her modem cause it was the nineties and not everyone had that modern stuff at home. It may have been a while ago, but definitely not ages. Feels like it tho, what with my phone being way more advanced than most people dreamed of back then..
@@killdolores I'm 28 and I remember this sound on my father's computer.
@@aaronhusar24 That's funny. I just turned 29 and remember it as well. We're all 28/29. Maybe that's around the youngest age of being able to remember it. Or maybe it's coincidence.
I can't even believe connection was based on audio wave rather than radio wave. I've learned sort of DTMF and FSK, but this thing is cool.
this video is not only super useful and interesting, but well edited and hilarious. not sure if you're still active, but i'm definitely subbing!
6:45 no it isn't, it's another probing signal by a calling modem to measure signal to noise ratio and some other things so the answering modem could start sending data in PCM modulated and correctly adjusted signal which gave you 56 kbit/s max (the last sequence is still random data as it was before that probing sequence, BUT the modulation is different - it was TCM before, now it's PCM). I didn't have this sequence in my country so I connected using V.34 protocol and my max speed was 33.6 kbit/s.
Wtf man?!? You forgot the "You got mail." Sound after all that noise

SacredGamer, GREAT video!
Antoon Veeve added the missing bit about the dialtone and the fact that the modem is first talking to the PhoneCo switch, before the other modem answers.
Do you know of a good description detailing the initialization similarities between modem and human communication?
Your voice and the way of delivering it is hilarious, almost sardonic and sarcastic. Love it.
Did you know that the dial-up sounds plays below 20 hz and those are sometimes called "ghost frequencies" they cannot be heard by us humans but they can make your chest heavy or make you feel like you're being watched, cool right?
It’s fascinating how computers from the 90s have better communication skills than I do with a singular person
So essentially, it’s an audible telepathic communication between machines. They greet one another, exchange personal information, then calibrate a communication bridge based on their unique information.
I think it's interesting that the sound of success @ 6:42 is also the sound they used in The Matrix when someone used a phone on the inside of the Matrix, and made a successful call to outside of the Matrix.
maybe they talk in aphex twin's language
lol
i can just imagine them talking to each other 3:42 its sooo cute ^v^
funny thing is that dial up internet is *literally* two computers ringing each other on the phone and "talking" to each other about stuff.
I barely understood what has happening and yet this video was entertaining and I managed to still “understand” it
WELL DONE🎉❤
It's crazy how we figured this shit out and how far technology has come in such a short amount of time.

What did you use for spectrum analyzing? I can't seem to find any thing similar to yours.
You can use Adobe Audition or maybe even Audacity (freeware) to look at a waveform like that. If I didn't know any better, I'd say that was actually an Audacity screenshot.
That's exactly what I was looking for. Thank you very much for this video.

"because it's a laptop." you do know they make usb modems, right?
The first time I accessed dialup internet was on my dad's work laptop. It was an old Toshiba Satellite with Windows 95. It had a built-in modem.
is nice how you researched all of this with all those sources posted on it.
so essentially it's a calibration conversation between two modems that in the '90's were having screaming matches after being woken up at stupid o'clock in its respective time zone.
So a late 90’s computer convo...got it :v
Honestly though this was very educational I liked it X3 who knew it was doing so many things so fast

Easy solution: Turn off your sound.
Pocoraven So what? You could then use ATM0 and/or ATL0 on the modem to completely disable it's internal speaker
Not sure why I randomly searched for this info and not sure why this very well put together video was made and waiting for me.
Yes, yes I will sub.
wow, I never knew what all those sounds were. Thanks! Kind of like a history lesson
Some of this is a bit wrong, or could be clarified better. The part where you say they are sending a bunch of random data is actually a probing signal to characterise the phone line signal loss. Analog lines attenuate different frequencies by different amounts, and this non linear behavior needs to be taken into account to maximize signal to noise ratio. Each side sends a signal that the other side analyzes. They then tell each other the results so they can adjust their transmission levels to maximize signal quality.
Next, the rising volume part right before the end is not a "victory"signal. Lol
Pots (plain old telephone service) lines can be converted from analog to digital and back again instead of being purely analog the entire span, especially long distance calls. This badly degrades the signal, but only for certain signal types. The modems can detect this with the special probing signal, and when it is detected (it isn't in this example), further negotiation must be done to figure out framing types on the digital part of the span, this allowing better signal usage and reducing the chance of corrupt data.
Why does it play though? Is it just to let the user know it's working?
THE MODEMS ARE HAVING A CONVERSATION THAT'S FUCKING ADORABLE

Thanks, you did a lot of work and I appreciate the education. You should have much more hits on this.
5:44 Dialup modems use a single carrier to transmit data (unlike DSL, which use Discrete Multiple Tones modulation for example).
With such technology, to transmit at a higher bit rate, you can either:
1. Transmit more symbols per second AKA increase the baud rate, but you need more bandwidth to do this (limited by the phone line capabilities).
2. Increase the quantity of information coded per symbol (bits/symbols), but you need a better signal-to-noise ratio to do so.
To improve the signal-to-noise ratio, you need a phone line with a flat frequency response (frequency selective fading introduces distortion), and predictable signal levels, which doesn't exists in the real world. However, the characteristics of your landline don't change over the time of your connection. Thus, modem designers introduced line probing to characterize the frequency response of the communication circuit, and feed correction data to frequency equalizers to compensate for your line's flaws. That way, your modem can pack up more useful information per symbol (less amplitude/phase distance between symbols, and more symbols with low absolute amplitude).
Weird how this sounds means a GOOD thing, given how intimidating and sinister it sounds especially towards the end. It sounds like just static and sounds of distress.
"Does everyone understand the video?"
"Totally! (I have zero idea.)"
If you promise not to ask anything more about it... then yes, I undestand completely...
You should do more videos like these. They’re really interesting.
6:59 'This is what you came to the Internet for, whether it be text or text.' Love it XD
OMG! This video made me think about old 90's modems and I have come to a conclusion! OLD 90's MODEMS ARE SELF AWARE!!! BECAUSE THEY KNOW HOW THEY SOUND! (I think that's why they made eathernet and Wi-Fi and completely ditched Dial-Up)
