Guides & Case Studies

A comprehensive guide to fundamental FIR filter concepts & applications in loudspeakers.

See a list of FIR-capable products (amplifiers, processors, media managers, players & plugins) including file formats and specific loading instructions.

Learn about the various ways you can work with IIRs in our software

This case study demonstrates step-by-step how FIR Designer can be used to tune a system using only IIRs (no FIRs)

Learn why some filters produce different results when used across processor brands.

Learn how to use FIR Designer’s built-in digital signal processor & audio player

The resulting FIR filters in this tutorial include the crossover responses and linearise the loudspeaker phase everywhere except at the loudspeaker’s low frequency roll-off. Sample measurements provided are taken from a 5″ coaxial loudspeaker. READ MORE

This tutorial describes how to adjust the magnitude & phase of a full range loudspeaker, using a FIR filter. Sample measurements provided are taken from a 12″ + horn install loudspeaker. READ MORE

This step-by-step guide explains how to use FIR Designer to upsample an existing FIR filter from 48 kHz to 96 kHz.

This step-by-step guide explains how to use FIR Designer to match the magnitude & phase responses of different makes & models of loudspeakers in a single installation.

Learn how to use FIR Designer’s integrated SMAART® Control to take a spatially averaged measurement with a single microphone, rather than averaging the response of multiple microphones at fixed positions.
