Dolby Atmos in Logic Pro

Part 1 – Dolby Atmos in Logic Pro

Atmos is a format that more and more people are recognizing and becoming aware of. It has been around in theaters and movies for many years, but in recent years the format has also started to make its way into the music industry. This article will be about how to get started with Atmos in Logic Pro and will be part 1 of the “Atmos in Logic Pro” series.

Setting up Atmos in Logic Pro

To open up Spatial Audio/Dolby Atmos in Logic Pro, you first need to go into the project’s settings. Once there, click on the audio category and then select Dolby Atmos from the “Spatial Audio” list.

Project settings → Audio → Spatial Audio = Dolby Atmos

Once you’ve done this, you can see Logic’s own “Monitoring Plug-in” on your Master channel. This will help you see your virtual room. You will also be able to switch between the rendering formats which can be explained as different formats for translating the sound into surround.

Tip: If you have Apple headphones or Beats, try Spatial Audio, otherwise you can start with Dolby Atmos.

Spatial Audio is Apple’s own “translation” for Surround in Atmos and Dolby Atmos is Dolby’s format. Dolby’s format is available on the Tidal, Amazon Music platforms while Spatial Audio is used on Apple Music.

For Atmos in Logic, Spatial Audio needs to be set to Dolby Atmos.

Setting up Atmos in the room

There are two options for setting up a rig for producing, mixing and mastering in Atmos.

Headphones

If you have Logic Pro and a pair of headphones, you’re basically good to go. This is a perfect way for you to try out Atmos as it doesn’t cost anything extra and is part of Logic Pro. If you have Apple’s own headphones (or Beats), you can also try their own Spatial Audio which is optimized for their own products. A cool effect you can try is “Head Tracking” which creates a virtual room around your head and allows you to move within it. This is also available in the Logic project so you can work directly in it.

If you use Apple’s phones and headphones, you can also scan your own face to create a unique listening profile optimized for you.

Speakers

Switching to a speaker system requires a little more work than using headphones. What you need are several (12) speakers and a sound card with enough outputs. You also need software to prevent phase errors and to calibrate the frequency response of the speakers. SubWoofer is not mandatory but is recommended to get a good reproduction in the low frequencies.

Some soundbars and homepods are compatible with Atmos, so if you already have one, you can use it as a quality check when mixing on headphones.

Phase and frequency reproduction

Something that is important when you have several speakers playing sound to the same point is not to get phase errors or miscalibration in the frequencies. To avoid this, you need a program that can analyze and adjust this for your speakers. You can do your own analysis and use Logic’s own EQ and Sample Delay for this. However, we recommend that you invest in a program such as Sonarworks. They help you with this and the calibration is applied to the sound on your computer, instead of in Logic Pro.
