Hi, my name is Jan Wilczek and 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!
In this video, I show you for steps needed to design and implement a parametric filter. Parametric filters arranged in a series make up a parametric EQ. The four steps are:
1️⃣ Decide on the filter type you want to implement.
2️⃣ Design an analog prototype.
3️⃣ Digitize the analog prototype using the bilinear transform.
4️⃣ Implement the digital filter in code.
I also give you a shortcut of steps 2 and 3 in the form of the RBJ Cookbook.
In case of any doubt in understanding, please, refer to the article above or ask a question in the comments 🙂

Have I helped you with this video? If yes, please, consider buying me a ☕ coffee at www.buymeacoffee.com/janwilczek Thanks! 🙂

[@noharahien]

Insane quality. Such an underrated channel. Thank you

[@stanleyrokita9919]

You are so good at explaining this stuff. Helping me a lot thank you

[@oberon2159]

Excellent video, thank you so much! Really helping me with my DSP module at university.

[@WolfSoundAudio]

Awesome, great to hear, Oberon ;)

[@TheBreakSpeed]

Tell me about it

[@ohnocoder]

By this video i'm learning math and english at the same time! You have good accent :)

[@WolfSoundAudio]

Thanks a lot!

[@tonyxiao4440]

very useful. Thanks for your video.

[@WolfSoundAudio]

Great to hear that!

[@przekladanki]

Nice background music ^^

[@WolfSoundAudio]

Thank you! :)

these math formulas are so confusing, isn't there a calculator where i put in the frequency i want to eq and it gives me the capacitors/resistors/transistors/whatever values so i can build it? i'm finding it crazy hard to find a way to reduce the volume at the 110-130hz range, i just want to solder things inside my speakers and passively reduce the volume only in this frequency range 😓

My parametric has 7 faders on my mixer. I dont use software.
