Logic Pro Exercise 2 – Recording a Dolby Atmos Master

Exercise Objectives:  

This exercise is designed to reinforce concepts covered in the first 6 modules of the training. The objective is to open a pre-mixed project in Logic, set up the Renderer based on that project, then create and record a Dolby Atmos Master.  

 

Dolby Atmos Renderer: 

  • Configure the Renderer as per Exercise 1 

 

Logic Pro:  

  • Close any open Logic project 
  • Open the pre-mixed project and ensure that you are in the arrangement view 
    • There are 2 pre-mixed projects in the Sessions folder of the exercise content (labeled as Mixed); either will work for this exercise. The timecode values and screenshots below reference the 95BPM project.  
  • Push play in Logic and navigate to the Renderer to verify that there is communication with the Renderer and LTC sync  
  • Ensure that the position display is set to Time

  • Move the cursor to beginning and end of the audio in the timeline to determine the in/out points to use in the Renderer. Round to the closest integer value before (for in point) and after (for out point)

  • In the mixer view, make a note of the tracks, clips, and their corresponding object assignments – these will be used in the Input Description window of the Renderer 

 

Dolby Atmos Renderer: 

  • Set up your input configuration: 
    • Open the Input Configuration window (Window > Input Configuration or Cmd+I) 
    • Click Groups to open the Groups dialog 
      • Add some custom group names that you will assign to objects (such as drums, bass, synth, vox) 
      • Click Close 
    • For each input, use the clip names from the Logic project to fill in the Description field, and assign to the groups you created 
    • Click Accept to save the input configuration 
  • Create a New Master File (File > New Master File or Cmd+N) 
    • Choose a Directory and filename 
  • Enable Record In/Out and set the In/Out to the time noted in your Logic project  
    • Note any offset required based on the LTC timecode. The LTC file provided with the exercise content starts at 01:00:00:00, so the timecode value will be offset by 1 hour

  • Arm Record 

 

Logic Pro:  

  • Start playback from the beginning of the timeline (timecode start)  
  • Navigate to the Renderer to verify that the recording has started 
  • When playback has finished, press stop in Logic 

 

Dolby Atmos Renderer: 

  • Once the Record Out timecode is passed, the Renderer will finalize the master file 
  • QC the recorded master: 
    • Disable sync in the Renderer 
    • Verify Input/Master switch is set to Master 
    • Click on the stop button to move to the start of the Master file 
    • Push play and listen to the entire Master file 
  • Open a finder window and navigate to the Master file. There should be a folder with a .atmos, .atmos.audio, and .atmos.metadata file
