Aliasing Exposed: Confronting Unwanted Harmonic Artifacts (Pure Data Demo) | Simon Hutchinson

A quick demo of aliasing in Pure Data. Aliasing (or "foldover") is unwanted frequencies created by sampling a sound below its Nyquist Rate. I talk about digital sampling and sample rate in more detail in another video (   • Sample Rate, Nyquist Theorem, and Anti-Ali...  ), but, in this video, I wanted to revisit aliasing specifically, demonstrating how these frequencies are created. #digitalaudio #aliasing #Nyquist #puredata 0:00 Defining aliasing 1:05 The patch 2:32 Demonstrating aliasing 4:21 Changing the sample rate 6:21 So what?
