Most air raid sirens produce an approximate square wave, with slight imperfections of course. I analyzed an audio clip of a Sentry 10V siren and found its wave to be nearly square.
@fort pingas Since I wrote that comment over 2 years ago I'm not even sure what my reasoning was, other than that I was specifically referring to mechanical sirens. I know most electronic sirens produce more of a sine tone.
The beginning minute or so is overwhelmed with dissonance of overtones getting alias-ed down (From limited sampling frequency). Can you re-synthesize this WITH an anti-aliasing filter and upload that ? cheers, P.
You're heading aliasing, from when the pitch is so high that it's overtones distort under the Nyquist Ceiling (22 kHz?) sampling rate ( 44 kHz? Here ) and become low-frequeny artifacts. I have slides on the topic, if you like...
Lol, it sounds like CrazyBus title screen theme. As far I know, it uses Texas Instruments SN76489 sound chip (added for backwards compatibility with Sega Master System) which used square wave sound instead of main MegaDrive sound chip Yamaha YM2612 OPN2 which uses 4 operators per channel FM sound with 8-bit PCM sound through integrated DAC (by sacrifice sixth FM channel).
@@nateflorendo Not a joke. Water resonates at a specific sound frequency. By listening to this (which goes down from a very high frequency to a very low one) the speaker goes through them so at some point the water vibrates and is ejected out. The Apple Watch does a sound similar to this to eject water out of the speakers when you leave underwater mode, there are slow motion videos here on RUclips showing it
@@TheCoreh when i watch this video my speakers dont vibrate that much but when i use a frequenty app and set it to like 10hz on square my speaker vivrate a lot is it because its different when you watch a video because its not actually a super low frequenty that your phone puts out?
bro thanks for uploading this. this is my favorite song.
la mia igual
Bro same
I found it to be a bit of a downer.

New Death Grips album sounds lit
Nobody:
Objects falling in cartoons:
A 3 and a half minute cartoon of someone falling
lol

1:20 uuuuuuuuuuuuuuhhhhhhhhhhh
Auuuuuuuuuuuuhhhhhh
Huhuhuhhuuuuuuuuuhuuuuuu
Where do all the random lower frequencies come from?
compression, probably
@@eblu_ Or they're introduced by the rapid changing of the frequency.

@@thepatrickrichardson Yes please!
@@thepatrickrichardson thanks man, will check them out
2:09 triggered
omg thank goodness i found this this will calm my nerves and brain thx so much
2:43 GET DOWN GET DOWN
THEY’RE IN THE TREES
Dead Dave vietcong ?
@@goodguyr1ch the cops
Some folks are born, made to wave the flag.
Ooh, the red, white, and blue
I thought Predator lol
Lmao I love finding my comments from a long time ago
0:29 fALLING
me when spicy chip
Me returning back from the void
At 1 Hz, it sounds like footsteps.
It reminds me of the cartoon falling noise
this song goes hard
When the bass About to drop
Appez It’s You!!!
Oh.

This actually helped my tinnitus.
this song lokey claps
0:30 highest note on piano
Right around 2:22 it makes you feel like you're shaking if you have headphones on
It did that for me around 10-5 hz
I can listen below 20Hz because the fourier series expension of 3f, 5f, 7f...... terms?
3:20 how do I hear this, it would just be a line
Any familiar sounds in here btw, guys?
You'll most likely hear this on the NES.
im playing this at the next woodstock
Can you make this but with the antialiasing filter?
This video tastes weird.
I use this to eject water out of my phone's speakers
Is this a joke or is it really working. Im confused

Did the plane crash?
I can hear SOME sine wave tone in headphones
Ear destructive.
Siren sound below 600 Hz almost
pixel falling
0:10 😧
0:03 sounds like coding
0:59 KOOL LAID MAN IS THAT YOU?
Headphones please
It starts at almost D10
I hate the youtube copyright bots.
I'm the 255th viewer😎
But we can't listen sound below 20 hz
Oh really? 🪄😏😉
sine wave
This is square wave not sine wave
The start of the video sounded like coding
Not long enough
я да

"i yes"
I y e s
Haha, someone made a copyright claim on this frequency demonstration.
*made
wtf
around 2:09 starts the brown note
