Back in November I had the opportunity to work on a multi-channel home theater sound system built with custom speakers. The client had their own Smaart rig so they measured the drivers and I worked on the EQ and crossover alignment within Crosslite. What follows are clips from the meeting transcript. We need for both of these drivers to be captured with the exact same delay locator value. Copy the delay locator value from your HF measurement. Paste it into your TF delay, and this time … [Read more...]
How to phase align main to sub in Smaart, REW, Open Sound Meter, SATlive, and Crosslite
The audio analyzer functions primarily as a verification tool. For this reason this article will focus on creating alignment presets, which can then be modified in the field using simple distance measurements. To fit this into a single article I will offer an overview of a single method for each software. Although the steps with each tool might differ slightly, in general they follow this pattern: Measure each source solo.Do whatever is necessary to achieve alignment.Measure sources … [Read more...]
Subwoofer Alignment at The Redmoor Cincinnati

Subwoofers are a big part of that low frequency content, supporting and extending its capabilities. However, subwoofers also require careful setup and alignment to ensure optimal performance. If you’ve ever had trouble getting your low end right, then you might want to read this article. It will explain why … [Read more...]
Know Your Audio Analyzer Averages
After you take several measurements and average them together, what do you expect to see? If these two measurements are averaged, what do you expect? Is zero the average of -6dB and 6dB, or something else? Here are four possible averages you may have guessed, depending on which audio analyzer you use. tl;dr Know what kind of averaging your audio analyzer uses.Collecting more data is more important than the way it is averaged. Here are demos from a selection of audio … [Read more...]
