    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:

    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.

      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.

  • @joeycaridi3030
    @joeycaridi3030 Před 2 lety +1

    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: czcams.com/video/98FgWHu2eI4/video.html
    Here's a video on the difference between an Absolute Sine Wave vs an Semisine Wave: czcams.com/video/gzdboOhx0IM/video.html
