#1 – 3 Simple Ways to Phase Align Main+Sub with SATlive

1. Make the pictures match.
2. Math (just a little!)
3. Automatic (Delay Suggestion Tool)

Make the pictures match.
This is the method I used for years and is the most common, but it has two problems: 1) It’s slow and 2) It’s not easy to tell if a polarity inversion is required.

Math
This makes the process faster.

Automatic (Delay Suggestion Tool)
This makes the process faster and can detect polarity inversion.

#3 – Where do I phase align a center sub?

My comments on Merlijn van Veen’s original article.

#4 – What does a full-range speaker look like in Smaart?

After you have practiced measuring an EQ, the next step is to measure a speaker in Smaart. Finally!

#5 – How loud does the test signal need to be in the room for Smaart?

How loud is loud enough? Program level? Speaking level?

You’ll be surprised to learn how quiet it can be to get actionable data in the high end and how loud it might need to be to get usable data in the low end.

#6 – Connecting Wavelength to Frequency

This is a method I learned from Dave Swallow to easily connect frequency and wavelength. If we know the speed of sound, then we also know any wavelength that is a multiple of 10, simply by moving the decimal place. Fun!
