While visiting a friend in The Big Smoke recently, I had an opportunity to assist in tuning a set of DIY speakers to his critical listening environment. This is a walkthrough of what we did, how it sounded, and lessons learned. I tried to present this in a step by step format so if desired, by following the same steps, you could obtain similar results. Here is pic of my friend’s rig:



Let’s ...

Now that we have a calibrated frequency response at the listening position, let’s look at the other part of the timbre (i.e. tone quality) equation which is the time domain. Sound in your listening room has 3 measurable dimensions: time, energy, and frequency. We have looked at frequency response, targeting the B&K house curve, and how it affects timbre. So how does the time domain in your listening room affect timbre?

As mentioned earlier, I had the privilege to work in many ...

This is Part 4 of a series on a quest to hear music the way it was intended to be reproduced. In the last 3 posts, we have “voiced” and calibrated our speakers to an equilateral triangle, took some frequency response measurements, analyzed the results, and introduced digital room correction (DRC). Let’s look at the frequency response measurement results and DRC in more detail. Is DRC ready for prime time? I think this post will show conclusively, yes, DRC is ready for audiophiles to take full ...

Now that my speakers are set up in an equilateral triangle, let’s take some frequency response measurements. First we need a calibrated microphone, software to perform the measurements, and a sound card. While there are several choices of measurement mics, acoustic measurement software, and sound cards, I will be using a MP-1r-KIT Acoustical measurement kit:" http://www.content.ibf-acoustic.com/...products_id=35, Audiolense software: http://www.juicehifi.com/index.html, ...

Part 1 is here. Thanks for your comments. Before we can measure the frequency response of your sound system at the listening position, we need to configure the speakers to the listening room. These set up steps are required in the quest to hear music the way it was intended to be reproduced – i.e. best effort timbre. This is the first part of a three part process. The three parts are setup, measure, and adjust. Then we iterate, sometimes a few times, sometimes more. It will cost you nothing but ...
