DSP Concepts
Use these technical articles & explainers to learn more about FIR filters as well as other DSP concepts relevant to loudspeaker and audio system design.
Understanding FIR Filters for Audio
A comprehensive guide to fundamental FIR filter concepts & applications in loudspeakers.
Same Filter, Different Results: Understanding IIR Variations between Audio Brands
Learn why some filters produce different results when used across processor brands.
Understanding Speaker Impedance

DSP Project Examples
These step-by-step examples show how to use FIR Designer software to solve common DSP design challenges.
Room tuning with only IIR filters
This case study demonstrates how FIR Designer can be used to tune a system using only IIRs (no FIRs).
The ‘Moving Mic Measurement’ Method
Instructions for using the MMM method of obtaining acoustic measurements, via the Smaart Control feature in FIR Designer.
Resampling (changing) FIR sample rates
Learn how to use FIR Designer to upsample an existing FIR filter from 48 kHz to 96 kHz. (The same process can be used for any supported sample rates).
Loudspeaker Matching with FIR Filters
Discover how to use FIR Designer to match the magnitude & phase responses of different makes & models of loudspeakers in a single installation.
Designing FIR Filters with Crossovers for a 2-way loudspeaker
This step-by-step guide uses a legacy version of FIR Designer (contains fewer features but essentially the same workflow as the latest version.)
FIR Filter Design for Loudspeaker Equalization
This step-by-step guide uses a legacy version of FIR Designer (contains fewer features but essentially the same workflow as the latest version.)
