Guides & How-To Documents

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

This case study demonstrates step-by-step how FIR Designer can be used to tune a system using only IIRs.

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.

This post explains 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.

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
