Acoustic Knowledge Base

In this video we show you how to set up Room EQ Wizard (REW) for acoustic measurement and analysis.

Learn the science of speaker placement and how room size and monitor specs impact positioning for optimal sound and accurate listening.

Room EQ Wizard is a free tool for measuring your room's acoustic response, and this tutorial walks you through every step — from downloading and installing the software to setting up your microphone, calibrating your soundcard, taking a measurement, and reading the resulting frequency response and waterfall graphs. Once you have your results, GIK Acoustics experts can help you interpret them.

What exactly should you listen for after installing acoustic treatment? GIK VP of Acoustic Design James Lindenschmidt explores the three pillars of the listening experience — attention, fidelity, and emotional engagement — and walks through what to expect when you treat bass, first reflection points, and rear walls. An essential read for anyone who has just treated their room and wants to understand what they're hearing.

Close-miking is the safe choice in an untreated room — but it limits what you can capture. This deep dive shows how the PIB™ Portable Vocal Screen opens up better mic placement options and makes recordings respond dramatically better to mixing and processing.

Getting your room set up properly is the foundation of good acoustics. This guide walks through speaker placement, listening position, early reflections, bass issues, and late reflections — with links to deeper reading on every topic.

Curious what acoustic treatment actually does to a room? See exactly what GIK Acoustics products were used in our real-world test room — and what a difference proper treatment makes to clarity, bass response, and reverb.

Even with great gear and acoustic treatment, poor monitor positioning can ruin sound quality. This guide explains common speaker placement mistakes and how to fix them using proper spacing, height, and toe-in. Starting with an equilateral listening triangle helps improve stereo imaging, balance, and overall clarity in studios, home theaters, and listening rooms.
