I found out a few months ago that the waveform I called semisine, is actually a parabola. Here's a video with the correct name: ua-cam.com/video/jUw8uiAc8Pg/v-deo.html
@@TruncatedTriangle Thanks. Realistically, it may be a while before I get round to it, (if I ever do). I already have a few a music projects on the go & limited time to make progress with them.
No, literally only saw and square are all that’s needed to make any synthesized sound so long as you also have a filter. Even crazier, if you use FM synthesis then theoretically all you need are sine waves to make any sound.
@@sibbyeskie *saw, square and a close attempt of triangle. The NES also couldn't handle saw waves without a Konami extension (I think it's Konami) and also used white noises to make percussion. It could also allow customized soundwaves. Same thing for the Gameboy, but it didn't alllow customized soundwaves.
Finally I found a video that describes the types of waves ... 1) Sine wave - 1 harmonic. 2) Triangle wave - all harmonics of a series of odd numbers, but from the first harmonic, each next harmonic will be 12 dB quieter than the previous one. 3) Sawtooth wave - all harmonics of a series of natural numbers and zero, but from the first harmonic, each next harmonic will be 6 dB quieter than the previous one. 4) Square (Impulse) wave - all harmonics of a series of odd numbers, but from the first harmonic, each next harmonic will be 6 dB quieter than the previous one. 5) Pulse wave - this type of wave has many positions from a square wave, but one part is slightly longer than the other to a square wave where only the shortest part of the time is spent on one part. 6) Semisine wave - all harmonics, but from the first harmonic, each next harmonic will be 12 dB quieter than the previous one. 7) Octave upping sawtooth wave - all harmonics of a row of even numbers, including zero, but from the first harmonic, each next one will be 6 dB quieter than the previous one.
Here's a more accurate description: Sine wave has only 1 harmonic. Triangle wave has odd harmonics, with each harmonic having the volume that is the inverse square of the harmonic number. (-12 dB/octave) Sawtooth wave has all harmonics, with each harmonic having the volume that is the inverse of the harmonic number. (-6 dB/octave) Square wave has odd harmonics, with each harmonic having the volume that is the inverse of the harmonic number. (-6 dB/octave) Semisine wave has all harmonics, with each harmonic having the volume that is the inverse square of the harmonic number. (-12 dB/octave) Pulse square wave is a square wave with different duty cycles, 0% and 100% being DC offset. Pulse triangle wave is a triangle wave with different centerings, 0% and 100% being a sawtooth.
An other waveform came into my mind, the noise, also rather frequently used. (like: drums and snares in FM synthesis) White noise definitely, but pink and blue noise have some specilialities too.
A triangle should sound like a muffled square, a semi-sine should sound like a muffled sawtooth, and both triangle and semi-sine should sound closer to sine.
A square wave is a type of pulse wave, it's just a square wave qith shorter high/low sections. A square is 50% because... It look's like a square (Wow who could have guessed!)
To make a Semisine Wave much more easier in an audio editing software just like creating Waveforms normally, you have to invert any 2nd half of the Sine Wave in the audio that goes from 180 to 360 degrees like near the beginning of the audio (Example: 10 milliseconds close to 0 seconds) so it can become a Absolute Sine Wave and then you'd cut out all of the regular Sine Waves and copy and paste the Absolute Sine Waves that appear in the audio to duplicate the Absolute Sine Waves. After that you'd then will apply the Remove DC Offset effect to change the Absolute Sine Waves into Semisine Waves. You'll also notice that near the beginning the Semisine Waves make a slide down shape which means you will cut that part out so the Semisine Waves are all even. After you've made your one Semisine Wave, you will then copy and paste the Semisine Wave and then copy all of the Semisine Waves that appear in the audio to duplicate the Semisine Waves until you feel like you've got enough. Also when you play your Semisine Wave you'll noticed that the frequency nearly doubled or completely doubled as you've chopped the Sine Wave in half, making the frequency almost or completely doubled which depends on how you converted the Sine Wave to a Semisine Wave. Here's an example video on what a Sine Wave looks like with angle degrees so you can use this video to convert from a Sine wave to a Semisine Wave: ua-cam.com/video/98FgWHu2eI4/v-deo.html Here's a video on the difference between an Absolute Sine Wave vs an Semisine Wave: ua-cam.com/video/gzdboOhx0IM/v-deo.html
If you're asking about the semisine wave, it will be the same as a triangle wave except with all harmonics instead of only odd. Or you could go to this video: ua-cam.com/video/PsGssgVPKAI/v-deo.html
Sorry I was hoping you'd explain. I know that we tune A to 440 Hz. Divide it twice to drop it 2 octaves, and it's 110 Hz. Do you mean that since 105Hz would be X cents flat of A, the bitrate limited to 44100 is creating some type of artifacts/overtones that are also flat?
@ivysaur the 19 dollar card wielder I was trying to recreate a moog bass and in most digital synths they call this shape trisaw, but in really it is a moog square(an analogue square). i think only in digital it is possible to have a perfect square wave. i figured it out

@@cycrothelargeplanet Yes
I've never come across semisine before. It sounds a bit like sine with a hint of saw. Interesting. I might have to sample it! 😃
That would be good if you did, we need more of these.
@@TruncatedTriangle Thanks. Realistically, it may be a while before I get round to it, (if I ever do). I already have a few a music projects on the go & limited time to make progress with them.
Square waves are the most nostalgic sound. Not just for video games of the 70s and 80s, but also for PCs.
SIne=BOOP
Square=BEYP
Sawtooth=BEP
Triangle=BUP
Semisine=BERP
Boop! Beyp! Bup! Beyp Bep Bup Boop... POW.
Boom...
Bam... Bap... Bada bap boom, *POW!*
Semisine waves sounds like a brass instrument
Square wave sounds like a cool metronome but also a jumpscare for people
So this is literally the fundamental sounds to make chip tunes?
Nice! New Knowledge Obtained.

Pulse triangle wave is a triangle wave with different centerings, 0% and 100% being a sawtooth.
Of course, I understand, but my definition is more disclosed ...
To sum up, it's all about the time.
People say there's no difference between sine and square waves.
*they haven't seen this video*
Hold up what kind of inexperieced person would say *this*
You would have to literally never hear of music OR never learn what waveforms are in order to be able to say that.
@Brayden Hicks they'd think differently even more if they spent 10 minutes on synth patch design and menu diving
Thanks. I needed the terminology for a report!
This is a good primer. I think the sound samples played for a bit longer would help make the sound more recognizable. Still a good video.
An other waveform came into my mind, the noise, also rather frequently used. (like: drums and snares in FM synthesis)
White noise definitely, but pink and blue noise have some specilialities too.
Noise is not a basic shape. It is a random arrangemant of frequencys.
The sawtooth wave is cutting my ears as if it’s an actual sawtooth
Good pun!
@@SubroOrbusyes 😅
Simple, clear, to the point. How is it that the best explanation videos are from the smallest channels? You got my sub and like.

so basically
triangle = square + sine
semisine = sawtooth + sine
now we need sawtooth + square

Love your videos, would love to see tutorials on how to make your wave forms and settings you set them too
I have something like that right here: ua-cam.com/play/PLBw4QsazXcDivywTYB78P2uexQu224BWJ.html
great video, loved it.
Am I hearing this wrong?
Triangle just sounds like sine but lighter & muffled
And semi-sine just sounds like a muffled sawtooth
A triangle should sound like a muffled square, a semi-sine should sound like a muffled sawtooth, and both triangle and semi-sine should sound closer to sine.
1:19 square sine + sawtooth sine
So this is what Lotus Juice meant when he says that Three Dots connect to rectangles
My friend aaron loves waves!
Waves are cool
I also love waves
I saw those colored pictures at wikipedia but where did you get the semisine pic?
I downloaded the SVG from that site, and edited the colors and created the semisine with inkscape.
thank you so much
for a basic video this had good info, learned a few things / tricks i could use for making sounds in a DAW
Amazing
Got sent here from my college lecture lol
youre a god(or goddess)
Thanks
Why isn't the semisine included most of the time?
I think it never came to anyone's mind
Plus, it has DC offset if you fill the entire positive and negative sides of a waveform.
0:44 Sine
0:47 Squre
0:50 saw

You forgot 0:56 parabola
very usefull
If there are Sine, Square, Sawtooth, Triangle and Semisine waveforms, how about Pentagon waveforms?
Impossible
There is one more waveform you forgot to mention. The pulse waveform.
Those are just halves square waves
A square wave is a type of pulse wave, it's just a square wave qith shorter high/low sections. A square is 50% because... It look's like a square (Wow who could have guessed!)
Ardennes I see, so in music when you use a synth sound, you can make it produce any waveform in any way you want.
SkyyySi This is commonly use in synthesis in electronic music.
One thing though, common doesn't equal basic. That's why it's not in this video.

Do sine harmonics with simple frequency ratios but different phases sound dirty?
By themselves, they don't. But with more at one, it depends.

why not cosine waveforms
They're the same waveform as sine waves. The only difference is that sines start on the center line and cosines start on one of the peaks.
