Future Filters

Forward-thinking filtering techniques

From surgical frequency-shaping to creative sonic carvery, the filter is one of the most essential tools in the audio professional’s arsenal. In the simplest sense, it’s a device that can be used to boost, attenuate or completely remove a signal’s frequency content, and is a fundamental process in many essential music production techniques such as equalisation, synthesis and sound design.

Over the next few pages, we’re going to explore the wonderful world of filters, both in the hardware and software realms. We’ve sought advice from one of the most revered software developers in the world, who’ll break down the underlying theory and science of filters, and exactly how they work under the hood, to give you a foundation of knowledge that we’ll then use to explore creative filtering techniques, mixing tricks and beyond.
