Sine waves are made up of only a single frequency, so it's not usually particularly effective to filter them.

This video falls somewhere between synthesis theory and a passionate rant. My simple statement is: "Don't filter sine waves." Now, it's not dangerous or anything. But trust me, it's usually not very effective.

I'll show you why filtering sine waves is often pointless and offer some alternative approaches to consider. While I'll be working in Reaktor, the concept applies to other synthesis environments like Pd, Max/MSP, and Kyma. Through a hands-on demonstration, we'll observe the behavior of sine waves and understand why they are particularly ill-suited for filtering. We'll explore different filters like high-pass, low-pass, and band-pass, only to realize their limited impact on a single-frequency waveform.

Fear not! We'll discuss alternative techniques that truly transform the sonic landscape. Wavefolding, waveshaping, and modulation synthesis will enter the picture, adding rich and diverse frequency components to your sound.
