Exercise Objectives
This exercise is designed to reinforce concepts covered in Modules 2 through 6. The objectives for this exercise are to import an ADM BWF, connect to and play back via the Renderer, and switch metering and measurement options. Refer back to the previous Modules if needed. Options for achieving some exercise objectives are presented. Become familiar with all of options presented.
Download the Exercise Content 2-3.zip to the Pro Tools workstation and unzip on the media drive.
Dolby Atmos Renderer
Follow these steps in the Renderer:
- Launch the Renderer. Set as per Exercise 1
Pro Tools
Follow these steps in Pro Tools:
- Launch Pro Tools if closed. Set as per Exercise 1
Prepare the session for ADM BWF import using one of the five options below. The first four prepare the I/O Setup for the ADM Import. The fourth will use the ADM import to create the I/O Setup.
Option 1 – Create session using I/O Setup from Exercise 1
- From the Dashboard
- Name the session Exercise 2
- In the I/O Settings drop-down menu select Last Used
- Set the File Type to BWF (.WAV)
- Set the Sample Rate to 48kHz
- Set the Bit Depth to 24-Bit
- Click Create
- Configure Session>Setup or press Cmd+2
- Set the timecode rate to 24
- Set the session start to 00:59:50:00
– Or –
Option 2 – Create a session using one of the supplied templates
- From the Dashboard
- Check Create from Template
- From the Template Group drop-down menu select Dolby Atmos Production Suite
- Select Dolby Atmos Renderer Dolby Audio Bridge Mono
- Name the session Exercise 2
- In the I/O Settings drop-down menu select Dolby Atmos Renderer Dolby Audio Bridge Mono
- Set the File Type to BWF (.WAV)
- Set the Sample Rate to 48kHz
- Set the Bit Depth to 24-Bit
- Click Create
- Configure Session>Setup or press Cmd+2
- Set the timecode rate to 24
- Set the session start to 00:59:50:00
- Alternatively, if the session is created from the Dashboard with the I/O setting set to “Last Used” the I/O setting file (.pio) can be subsequently imported.
- Go to Setup>I/O
- Click Import Settings and select Dolby Atmos Renderer Dolby Audio Bridge Mono
- Click Ok
- Click Yes when presented with the Delete unused busses dialog
- In the Bus tab, click the 7.1.2 Bed Mapping to Renderer checkbox to assign the Bed to Input 1-10
- In the Bus tab, mapping of all Object busses will be displayed in the Mapping to Renderer column
- In the Edit window Option Click on a track name to select all tracks
- Delete all tracks Tracks>Delete. Your ADM BWF import will create the tracks in a later step.
– Or –
Option 3 - Create a new session and set up the I/O manually:
- From the Dashboard
- Name the session Exercise 2
- Uncheck Create from Template if checked
- In the I/O Settings drop-down menu select Last Used
- Set the File Type to BWF (.WAV)
- Set the Sample Rate to 48kHz
- Set the Bit Depth to 24-Bit
- Click Create
- Configure Session>Setup or press Cmd+2
- Set the timecode rate to 24
- Set the session start to 00:59:50:00
- Go to Setup > I/O
- Delete all existing Output paths from the Output tab.
- In the Output tab, set the Default Format to 7.1.2, and set the Path Order to SMPTE.
- Add new Output paths:
- 1 x 7.1.2 output for the Bed. Name this 7.1.2 Bed.
- Check Add default channel assignments
- 118 x mono outputs for the Object. Name these Object. (Pro Tools will label these Object1 through Object 118 automatically.)
- 1 x mono output for the LTC Generator (if needed). Name this LTC Gen. This will be automatically assigned to the next available output 129.
- In the Bus tab, click the 7.1.2 Bed Mapping to Renderer checkbox to assign the Bed to Input 1-10
- In the Bus tab, map the mono Object busses 1 to 118 to Renderer Inputs 11 to 128
- Shift-click from Object 1 to 118 to select all Object busses, then hold Cmd+Option+Shift and click the Object 1 Mapping to Renderer field check box. This will sequentially cascade Object metadata assignments to the same Renderer inputs as the Object audio paths across all Object busses.
- Verify mapping to Object assignments have been set correctly; then click OK.
– Or –
