Aliasing and Bandlimited Waveforms | Plugdata Course for Beginners Ep. 9

Описание: This video delves into aliasing, a phenomenon that occurs when a signal is sampled at a rate that is too low to accurately represent its high frequency content. You'll learn about:
🔸Sampling theorem
🔸Aliasing
🔸Dumb filtering
🔸Bandlimited Waveforms
🔸How to synthesize triangle, saw and square waves from scratch

Plugdata, https://plugdata.org/download.html, is a visual programming environment for audio experimentation, prototyping, computer music and education. It is based on Pure Data and provides a user friendly interface for creating and manipulating interactive audio systems.

While this course was specifically designed for Plugdata, don't worry if you want to learn Pure Data. The fundamental concepts and techniques I'll cover in the first episodes are the same across both platforms. You'll learn the basics of signal flow, object patching, and audio processing, which are essential skills for anyone working with visual programming and digital audio synthesis. I hope this course will be a great learning resource for your creative journey!
