Hi, my name is Jan Wilczek. I am an audio programmer and a researcher. Welcome to WolfSound!
WolfSound's mission is to provide high-quality, informative, and entertaining videos, articles, and courses on how to process sound by exploring mathematics, applying algorithms, and creating code in various programming languages. Topics include sound synthesis, digital signal processing, programming languages for audio (C, C++, Python, Rust), and audio effects. I am also sharing tips on how to learn fast and effectively. Make sure to visit www.thewolfsound.com/.
WolfSound enables everybody to learn about audio programming!
ABOUT THE VIDEO
In this video, you will learn everything on basic waveforms in sound synthesis:
➡️ sine,
➡️ triangle,
➡️ square,
➡️ sawtooth (saw), and
➡️ pulse.
For each of these waveforms, you will learn
➡️ its mathematical formula,
➡️ how it sounds,
➡️ its amplitude spectrum, and
➡️ its time-domain visualization.
This knowledge will allow you to
✅ use sound synthesizers more consciously,
✅ achieve the timbre you desire,
✅ use these signals effectively in DSP applications,
✅ detect bugs in you audio software (audio plugins, game audio), and
✅ achieve powerful effects with low-frequency oscillators (LFOs) as modulators; controllers of audio effects.
In case of any doubt in understanding, please, refer to the article above or ask a question in the comments 🙂

Im loving ur videos, it would be amazing to see full tutorial of making a synth in C++. From start to finish including gui

[@WolfSoundAudio]

That's in plans, thanks for writing this! Will make me more dedicated to it 😉

[@ishumshark9209]

This channel is super under appreciated. The quality is soooo high.
I wrote a simple wavetable synthesizer in Julia using your Python wavetable synth tutorial, and my next goal was adding new waveforms while avoiding aliasing. I'm gonna try and construct some band limited waveforms using the information from this video! Thanks!

[@WolfSoundAudio]

Awesome, congratulations and thank you!

[@masterpiecemusic9878]

Thanks for sharing your super technique and very in-depth knowledge. Fabulous, staet-of-the-art presentation.

[@SEOTADEO]

Your videos are really good!

[@andrewsmail8307]

Very intersting thank you.

[@ab2_3000]

Very educative content

[@rubevanderwielen9323]

I learned a lot from this video, but i still have a question. what's the difference in sound between a ramp-up saw and a ramp-down saw?

[@landegard]

Thx for this video and all other about create sounds

[@WolfSoundAudio]

You're welcome! :)

[@ananthakrishnank3208]

Thanks a lot!
1. For sawtooth, using 'ft' instead of 't' leads to f squared nom of peaks instead of f no. of peaks (which I expect)

[@ab2_3000]

Would you mind sharing how to tempo sync a tremolo

[@user-fm8hq3fm2d]

Sine 2:35
Triangle 3:18
Square 4:36
Sawtooth 5:31
Pulse 7:19

[@WolfSoundAudio]

Thanks!

[@maximpshonka8148]

is the formula for pulse wave correct?

[@SergioGarcia-bb8mr]

I would've appreciated each of the different waves being played back to back at the end, to better hear their differences. Being spaced out, I couldn't tell them apart.

[@maldananimation4978]

Sawtooth formula is incorrect. It's not ft it's must be t

[@dodgingrain3695]

These are not particularly useful for synths, they are too perfect.
