🎛️ The Best Free Tweak You’ll Ever “Buy” — Room EQ Wizard (REW) Demo & Overview

Today, we’re diving into Room EQ Wizard — better known as REW — a free software tool that can dramatically improve your sound system’s performance. Whether you’re tuning a full-blown home theater or refining a two-channel setup, REW gives you accurate, repeatable data that reveals exactly what your system and room are doing.

I call this “the best free tweak you’ll ever buy” because once you understand how to use REW, you can identify room modes, flatten response, improve subwoofer integration, and get your system sounding better than any cable or accessory ever could — all without spending a dime.
In this demonstration, I walk through:

🎤 Tools You’ll Need — affordable measurement mics, USB setup, HDMI routing, and mic placement
📈 Taking Measurements — what to measure, how to label, and how to interpret frequency response
🧠 Understanding What You See — room modes, speaker boundary interference, and Schroeder frequency
🎚️ Applying EQ Correctly — how to use REW filters without overcorrecting or introducing distortion
📊 Analyzing Results — reading decay plots, impulse responses, and wavelets for time-domain accuracy
🎧 Real Case Study — using REW to transform $50 Dayton Audio speakers into something truly listenable
This talk also touches on distortion analysis, how to decide what “flat enough” really means, and the limitations of EQ versus proper room treatment.

🧰 Why It Matters
REW isn’t just for engineers — it’s a practical tool that helps enthusiasts hear what their systems are truly doing. You’ll learn how to measure what matters, understand what’s fixable, and stop wasting money on tweaks that don’t make a real difference.
