MPEG-H Authoring Suite

With its unique personalization features, the MPEG-H Audio system offers fully adjustable dialogue levels, customizable audio description, multiple languages, and even interactive object positioning. As a result, users can tailor the media consumption experience to their individual preferences and needs. MPEG-H delivers these unprecedented customization options, as well as enveloping immersive sound, on every kind of playback device – from home theaters to 3D soundbars to mobile devices.

The MPEG-H Authoring Suite (MAS) is a set of tools that make the production of MPEG-H Masters easier, faster, and available for everybody. With updates for all tools, the MPEG-H Authoring Suite's version 3.7 will accelerate your MPEG-H production workflows even more!

MPEG-H Authoring Plug-in: Capabilities and highlights#

The MPEG-H Authoring Plug-in (MHAPi) takes you through all the steps of creating object- or channel-based MPEG-H Audio productions inside a VST3- or AAX-enabled Digital Audio Workstation (DAW). You will be able to export your immersive and interactive MPEG-H Audio scenes to either MPEG-H Production Format (MPF), or MPEG-H BWF/ADM, containing audio and metadata, ready for distribution via MPEG-H-enabled channels.

With the MHAPi 3.7 you can even import static and dynamic metadata from an existing MPF file back into your DAW. Please refer to the user manual for a step-by-step guide.

  • Combination of channel-based components and dynamic audio objects
  • 3D panning and 3D position automation of dynamic objects for immersive content
  • Dynamic Gain Sequences
  • Enabled interactivity on component gain and position for an interactive user experience
  • Create labels in multiple languages for audiences all over the world
  • In-depth documentation and template sessions for Pro Tools, Nuendo, Reaper and Sequoia
  • Export to MPEG-H Production Format (MPF), MPEG-H BWF/ADM or XML
  • Now supports monitoring layouts up to 22.2
  • Improved binaural monitoring for immersive audio reproduction over headphones
  • Options for binaural authoring including the option to bypass binauralization on a per component basis (mono/stereo)
  • Improved routing capabilities
  • Additional component layouts for better DAW integration (7.1+2, Quad Height, …)
  • Assisted authoring mode for faster MPEG-H authorings
  • Improved object panner
  • Improved user experience

MPEG-H Authoring Tool: Capabilities and highlights#

The  MPEG-H Authoring Tool (MHAT) is a software tool for macOS and Windows for creating MPEG-H metadata with existing audio material. The MPEG-H Authoring Tool allows for easy MPEG-H authoring without the need of a Digital Audio Workstation (DAW). You can define specific MPEG-H parameters, instantly listen to your configurations and export your authored mixes as MPEG-H Production Format (MPF), MPEG-H BWF/ADM or as a template XML file.
  • Now supports monitoring layouts up to 22.2
  • Author MPEG-H metadata with previously produced wave files
  • Combination of channel-based components and dynamic audio objects
  • Enabled interactivity on component gain and position for an interactive user experience
  • Create labels in multiple languages for audiences all over the world
  • Binaural monitoring for immersive audio reproduction over headphones
  • Options for binaural authoring including the option to bypass binauralization on a per-component-basis (mono/stereo)
  • Import and export of MPF and MPEG-H BWF/ADM
  • Export session templates for use in broadcast devices
  • Streamlined export and loudness measurement process for even faster results

MPEG-H Conversion Tool: Capabilities and highlights#

The  MPEG-H Conversion Tool (MCO) is a software tool for macOS and Windows that converts MPEG-H compliant content masters between different file formats. The MCO serves as an interface to the MPEG-H Audio ecosystem and supports the import and export of MPEG-H Master files. With the option to import BWF/ADM files that were created by other tools, it is now up to the users to choose their preferred toolkit for production. After conversion via the MCO, the resulting files can even be edited and enhanced using the other MAS tools’ advanced feature set. That way, MPEG-H authoring integrates easily into most existing workflows.
Selected Highlights of the MPEG-H Conversion Tool 1.2.0:
  • Now Supports Import of IMF/MXF/IAB and DCP/MXF/IAB
  • Allows direct conversion of object-only content for music productions
  • Improved 3daa 360RA level 3 support (including LFE handling)
  • Support for MPEG-H Masters with up to 32 channels
  • Improved user experience

MPEG-H Production Format Player: Capabilities and highlights#

The MPEG-H Production Format Player (MPF Player) is a software player enabling quality control of files containing video and associated MPF audio. The MPF Player supports a variety of video formats, such as ProRes422 in a MOV or H264/H265 in an MP4 container. With the MPF Player, there is now an easy way to play back your master files including MPEG-H Audio before encoding, check for A/V sync, review the scene authoring, preview interactivity, and monitor in a variety of different render layouts – from mono up to immersive loudspeaker setups or binaural rendering.
