In the context of the 3GPP activity on the definition of Audio media profiles for Virtual Reality (VR) streaming services, several candidate solutions have been considered. The submission process of Audio media profiles included various tests characterizing the solution performances. The present document presents the detailed test results provided by the solution proponents and the crosscheck labs.

The results were not compiled to any merit figures of the candidate solutions hence no such merit figures were used in the selection of the profile. The test results provided in the present document were not generated to be used in direct comparison.

The present document is a collection of test results on candidate audio media profiles for VR streaming services over 3GPP. A brief description of the 3 tests characterizing the audio media profile performances is presented under clause 4. The following clauses provide the test results from the audio media profile proponent as well as those from the crosscheck labs. The four documented solutions are (in alphabetical order):
  • Metadata Assisted EVS Codec (MAEC)
  • OMAF 3D Audio Baseline Profile
  • Spatial AAC extension (spAACe)
