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 https://www.thewolfsound.com/.

WolfSound enables everybody to learn about audio programming!

ABOUT THE VIDEO

In this video, I present allpass-based lowpass and highpass filter structures with real-time cutoff frequency control.

You will learn
💡 What is the problem with most IIR filter design methods when it comes to music applications,
💡 What are lowpass, highpass, and allpass filters,
💡 How can we use allpass filters to design real-time controllable lowpass and highpass filters,
💡 How to implement the resulting structure in the Python programming language.

In case of any doubt in understanding, please, refer to the article above or ask a question in the comments 🙂
