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.

Stream transfer function and spectrum files from the Smaart measurement software in real-time

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.

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

Learn how to use FIR Designer for Impulse Response Windowing, FIR Filter Windowing and FIR Filter Re-windowing (Conversion)

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.
