Any other waveform than Sinus produces harmonics. To figure out, how they sound, I have written a Pulse-Quad-Morpher, which morphs a Pulsewave with different pulse width (middle slider) into a quadric curve waveform (top slider). The bottom slider is to adjust the frequency. Note, that zero and one are illegal values for the pulse width, since only one value is produced, which is not a waveform.

Caution: Old Macs may produce noise.
This is a bug - upcoming audiostudies will run fine.

Neat… if you turn the frequency all the way down then drag one of the other sliders around, it sounds a little bit like a light saber battle :)

You’re right about the lightsaber battle :D

If you notice it getting louder and softer, its not (unless for some reason its coded in to just that? but i doubt it) our mid level of hearing is the loudest, and the further you stray the quieter noises appear. Thats why dogs usually respond to lower (male) voices and cats ignore you (they are higher on the spectrum)

just a fun fact!

very cool

Sounds a lot like my old 56k modem!

Really Cool!!!

Who did the web design?

Lol very funny, yet very painful.

Would like to learn how to use neat sound generation code, such as used here, into various animations. Any hints on where to start looking would be very much appreciated. Great samples!!!

now that is just sweet. keep up the good work

hola c

Hey please share with me how you did this? Will this also work with wav files (I’m assuming you’re doing with a tone generator). I am very interested in this and would like to pass code back and forth if you’re interested.

It can be used with the sound of car engines.

I like this this now if only I could use this in my Latin Salsa Music. It’s great for learning acoustics. Also there is something that sounds like a heartbeat under it. If I coud just get to control over it to use it like a musical instrument also.

if you put the first slider all the way to the left and put the second about 3/4 of the way, it sounds like a retro game

put the top slider all the way to the left. put the middle one to the left but not all the way, leave about a slider’s distance between the end and the slider. now, put the bottom one all the way to the left and gradually move it to the right. and think about the Nintendo game Excitebike. hell yeah.

painful! at the very least :(.

ha, ha! i made-ed a po-lice siren! keep up the gooooood work ! :p

It will be cool to make a moto or car game with this code as “Adam” said.

:D

very cool and simple :P its just a graph and every point has a different note but not so easy to make :D

Jesus, that thing is amazing but it’d be torture having to listen to that for a length of time!

HAHAHAHA LOL THIS GAME IS SUPER CRAZY

it a flyer

Very nice, but maybe you should add a button to turn the sound on/off. I was rather startled when I stumbled upon this page after a spell of silent web browsing with my speakers turned up.

I think I will try to recommend this post to my friends and family, cuz it’s really helpful.

I wish i had three hands and three mice
