Merlijn van Veen published a great video called Summing Sine Waves with Phase Offset. The relationship of two phase angles and their same seem to create shapes that you can use as mnemonic devices.

  • Milestone 55° phase shift = +5dB = 1.8:1 = parallelogram on the phasor scope = conjugate angle of 305º
  • Milestone 90° = +3dB = 3o’clock = 1.4:1 = square on the phasor scope = conjugate 270º
  • Milestone 120° = 0dB = = 1:1 = 1/3 cycle = conjugate 240º
  • Milestone 150° = 0.5:1 = -6dB (-5.7) = conjugate210º
  • Milestone 180° = -inf = 1/2 cycle = tug of war

In 2019 Sound Design Live had 206k unique pageviews from 107k users, 330k video views for 23k hours of watch time, 75k engaged users on Facebook, and 131k plays on SoundCloud. It looks like video is starting to outpace the podcast in terms of maximum outreach.

  1. How to Time Align Your…

I know you want to use the new beta version of Smaart, but you haven’t found time, yet. This 3-step hack will have you up and running in about 5 minutes.

Steps

  1. In Smaart v8, Config > Manage Configurations > Current Config > Save As.
  2. In Finder, ⇧⌘G then ~/Documents/Smaart v8/Config and copy the config file you just saved.
  3. ⇧⌘G then ~/Documents/Smaart v8/Beta Config and paste it.
  4. In Smaart v8 Beta, Config > Manage Configurations > Stored Configs > Recall.

Now all of the settings you worked for years to customize will be imported and you can start working immediately instead…


To time align your Main to your Front-fill using Smaart, first find the acoustic crossover point where they have matching level, then match their arrival times using the delay finder.

Setting the delay for the front-fill speakers is a very easy process using Smaart. The challenge is in choosing the correct measurement microphone location. If your mic location is too far into the audience, your front-fills will be too loud, tearing off the faces of the season ticket holders in the front row. …


I’m bringing together some of my favorite teachers for two full days of online live sound training and networking that will cover topics from mixing to sound system tuning. Sign up here.

#1 — Laughing with Jon

One of my favorite sessions from Live Sound Summit in 2018 was How I Approach a Soundcheck with Jon Burton. His technical training was great, but the best part was really that Jon has stories to back up everything that he teaches and most of them are hilarious.

#2 — Networking with Bodo

Networking is definitely a weak point in my training. I have some templates for how a few things work, but…


To prevent feedback from your podium microphone and create the most natural sound, measure the sound system in Smaart, but use the podium mic as the measurement input.

Podium microphones can be a struggle. It’s nice that they are generally reliable and everyone knows how to use one, but they are also static. They don’t track anyone’s height or movements. This means wildly different levels for the sound engineer. …


One thing I do to prepare for every show is to create a sound system tuning checklist and map. That way I know what to do and where to do it.

Make a plan. Work the plan.

Why?

First, it allows you to think through your actions. What system tuning procedures must you complete and in what order? How can you arrange those actions for maximum efficiency? (aka minimum number of microphone moves)

Second, it allows you to be more creative and flexile in the field. We all know once we arrive on site tomorrow, many things will change…


At first, using a custom weighting curve in Smaart seems like a brilliant time saver, but it turns a guide into a rule and could make your optimization procedure too rigid.

A custom weighting curve is like a filter for your data, similar to a microphone correction curve. Its intention was to add A and C weighting to Magnitude and RTA graphs, but Smaart makes it really easy to turn your target trace into a weighting curve as well. Then, instead of matching your measurements to a target trace, you can simply match them to the 0dB line.

Here’s an…

History of Mainland and Subterra

Throughout recorded history, the peoples of Mainland and Subterra have lived in harmony with one another. Though located on opposite poles of the planet Boh, each nation boasts ample quantities of Magnitude, the most valuable element found on Boh.

Though distant from each other, the two nations are connected by a thin but continuous land bridge that crosses the Sea of Spektral Xovr between them. This bridge has held solid for centuries. Forged from a perfect match of Magnitude…


One of the first steps in the Audio Analyzer Verification Checklist is to verify that Smaart is receiving all inputs. You can do this very quickly by pressing play on all inputs and then pressing the 0 (zero) key.

#2 Align all visible traces

Shift-click on any magnitude trace to align all visible traces at that frequency.
