Closing Audio Plenary and meeting deliverables

1. Plenary discussions

It was the consensus of the Audio subgroup to adopt the Sys2 Binauralization technology (from the Binauralization CE) into the CO portion of 3D Audio WD and RM. This includes a normative (and fully disclosed) BRIR to parameter conversion process.

It was the consensus of the Audio subgroup to adopt the BRIR to parameter conversion for the Orange time domain binauralization as normative (and fully disclosed), and to incorporate this into the integrated into the HOA portion of the 3D Audio WD and RM.

Concerning m32182, Max Neuendorf, FhG-IIS, made a short presentation that reviewed a portion of what was proposed in the contribution:

• 
  Specifying number of audio channels, object channels and SAOC channels.
  
• 
  Specifying that the order of these channels in terms of the USAC3D channel elements, and mapping these to the next block in 3D Audio decoder processing
  

It was the consensus of the Audio subgroup to incorporate the following technologies into WD1:

• 
  Specifying number of audio channels, object channels and SAOC channels.
  
• 
  Specifying that the order of these channels in terms of the USAC3D channel elements,
  

Concerning

• 
  mapping channels in terms of the USAC3D channel elements to the next block in 3D Audio decoder processing
  

All experts agree that this proposed functionality is needed. At the face-to-face AhG meeting, there can be contributions to propose alternate solution, and a final decision will be made at that meeting.
