Pro Tools 2021.7

Bed/Object Groups and Channel Descriptions are no longer carried over when switching connections for the Dolby Atmos Production or Mastering Suite to the Cinema Renderer (PT-26874

Pro Tools 2021.3

Easier Setup of Stereo Objects

  • It’s now possible to automatically create stereo mapped objects based on the connected renderer input configuration. This can be done by selecting “Use Dolby Atmos Renderer (Stereo)” in the I/O Setup bus tab, and then clicking the default button. There is also an option for mono.

    Bed/Object Fold Down

  • Beds are now included in the fold down path making it easier to monitor a rough mix when a Dolby Atmos renderer is not available.

    Always Fold Down

  • You can now choose to always enable the channel-based fold down path for a Dolby Atmos mix. This is useful if you require a rough headphone mix for editorial while the main mix is fed through a renderer. It is also useful if a system does not have a renderer connected, and the mix needs to be monitored for non-mission critical tasks.

    Faster ADM Bounces to Network Storage

  • A new preference has been added, called “Use Local Cache When Bouncing to Network Volume.” This significantly increases the speed of the bounce process in certain circumstances. It works by automatically bouncing to a local cache location when pointing the Bounce Mix window to a network volume. When the bounce completes, the cached file is immediately copied to the network location, and then the cache is cleared. While this was primarily designed to help bouncing to WAV (ADM BWF), it also works with WAV (BWF) when using the Single File Delivery Format option with multi-stem bounces.

Pro Tools 2020.12

Object Control Mode must now be set to Master on at least one object track in order for the object to be included in the ADM BWF bounce (PT-267351)

Defaulting the I/O setup with “Use Dolby Atmos Renderer” selected will once again default outputs in SMPTE order (PT-267198)

Importing an ADM file will now result in a SMPTE order output IO Setup (PT-267976)

An extraneous Session Notes warning will no longer be presented, after importing session data, if an object results in being mapped to the same renderer input as the source session or ADM file (PT-268065)

Improved round trip pan breakpoint accuracy with ADM BWF files by now including the original breakpoints in the bounce, as well as the breakpoints required for the renderer to decode and playback accurately (PT-267405)

There is now a Cancel button available during ADM BWF import (PT-267640)
Fixed an issue that would cause the Bed / Object Group window to become stuck on Windows OS (PT-267215)

Entering ‘localhost’ in the Peripherals Dolby Atmos RMU Host section will no longer be case sensitive when used in conjunction with Dolby Audio Bridge (PT-258935)

Pro Tools 2020.11

Dolby Atmos ADM BWF Expor

(Pro Tools Ultimate Only)

“Dolby Atmos ADM BWF” has been added as a new exportable file format in the Bounce Mix window. This allows for much quicker deliverable turnarounds with offline bounces directly from Pro Tools. It’s possible to generate new deliverables from a new project, with new metadata, or rework previous ADM files, passing along or changing the previous metadata.

Pro Tools 2020.3

  • Fixed a crash when opening a session that contains Dolby Send and Return Plug-ins. (PT-256062)
  • A progress bar is now present when importing larger ADM files (PT-230490)

Pro Tools 2019.10

Dolby Audio Bridge Support for 130 Outputs (Pro Tools Ultimate only)

Pro Tools now supports 130 outputs via Core Audio when used in conjunction with the Dolby Atmos Production Suite and the Dolby Audio Bridge. 128 channels can be used for beds and objects, while the additional 2 may be used for sending LTC. This streamlines setup procedures and helps facilitate the use of Dolby Atmos tools in a self-contained local environment. It also allows for accurate Automatic Delay Compensation (ADC), as well as easier session interchange between Pro Tools systems working with the Dolby Cinema RMU or Dolby Atmos Mastering Suite.

Note: This feature is intended for smaller mixes or editorial where the CPU load can be handled on a single system. For larger more demanding mixes, or if the SYNC HD is needed, the Dolby Mastering Suite or Cinema RMU may be more appropriate.

It is important that device clocking is configured appropriately when using the Dolby Audio Bridge. This is will prevent audible artifacts.
