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.
