Example Configuration Files

• fix_dolby.json

  fix issues in Dolby Atmos ADM Profile files to be compatible with the BS.2127 renderer

  runs fix_ds_frequency, fix_block_durations and fix_stream_pack_refs.

  required options: input.path and output.path

• track_stream_to_channel.json

  replace audioTrackUid->audioTrackFormat->audioStreamFormat->audioChannelFormat references with audioTrackUid->audioChannelFormat references

  runs convert_track_stream_to_channel and remove_unused_elements

  required options: input.path and output.path

• render.json

  render an ADM BW64 file

  runs add_block_rtimes and render

  required options: input.path, render.layout and output.path

• measure_loudness.json

  update the loudness of one audioProgramme in a BW64 wav file

  this currently works by rendering the programme to 4+5+0 and measuring the loudness of the output, so this may not be accurate for channel-based content which would be better measured directly

  required options: input.path and output.path

• measure_all_loudness.json

  update the loudness of all audioProgrammes in a BW64 wav file

  this currently works by rendering the programme to 4+5+0 and measuring the loudness of the output, so this may not be accurate for channel-based content which would be better measured directly

  required options: input.path and output.path

• conform_block_timing.json

  conform the timing of object type audioblockformats to the emission profile

  this first removes the jump position flag from any audioblockformats in which it is present. these blocks are replaced with multiple blocks representing the same change where appropriate. it then ensures no block other than the first is shorter than 5ms in duration by combining short blocks, starting from the end.

  required options: input.path and output.path

• conform_to_emission.json

  read and write an ADM BW64 file, applying various processes to make it closer to the emission profile

  required options: input.path and output.path

• validate_emission.json

  read an ADM BW64 file and check it for compatibility with the emission profile

  required options: input.path
