Understanding Filters Part 1 – Low Pass 

For anyone who has programmed a synthesizer or sampler, the word “filter” should be all too familiar. In this tutorial series, we’ll get acquainted with the characteristics of the three basic filter types, and use them to make some production-ready sounds.

First off, we’ll get some bass time in with the big kahuna: the Low Pass filter. To start, it’s important to understand what “Low Pass” actually means. Most filters are set using a parameter called “Cutoff”. In a Low Pass filter, frequencies below the cutoff frequency are passed, while those above are attenuated. This makes modulating (or moving) the cutoff useful for changing the brightness of the sound over time. This is the essence of subtractive synthesis: systematically removing frequencies from a big, bright waveform to create something unique and musical.

A simple sound made using a low pass filter and basic oscillator is a thunky bass. This basic sound is adaptable to many musical styles, from the club to the car and beyond. – Evan Sutton
