-scene_orientation  : Scene orientation trajectory file. Only used with rtpdump output.

-device_orientation : Device orientation trajectory file. Only used with rtpdump output.

The usage of the "IVAS_dec" program is as follows:

--------------------------------------------------

-exof File          : External orientation trajectory File for simulation of external orientations

-dpid ID            : Directivity pattern ID(s) (space-separated list of up to 4 numbers can be 

                      specified) for binaural output configuration

-aeid ID            : Acoustic environment ID (number >= 0) for BINAURAL_ROOM_REVERB output config.

-aeid ID | File     : Acoustic environment ID (number > 0) or

                      alternatively, it can be a text file where each line contains "ID duration"

                      for BINAURAL_ROOM_REVERB output configuration.

-obj_edit File      : Object editing instructions file or NULL for built-in example

-level level        : Complexity level, level = (1, 2, 3), will be defined after characterisation.

-om File            : Coded metadata File for BINAURAL_SPLIT_PCM OutputConf

--------

-i File             : Input audio File (WAV, raw PCM or scene description file)

-if Format          : Audio Format of input file (e.g. 5_1 or HOA3 or META, use -l for a list)

-im Files           : Metadata files for ISM (one file per object) or MASA inputs

                      META is related to the Scene description file, see scripts/testv/renderer_config_format_readme.txt

-im Files           : Metadata files for ISM/MASA/OMASA/OSBA/BINAURAL_SPLIT_PCM (one file per object). 

                      For OMASA input, ISM files must be specified first.

-o File             : Output audio File

-of Format          : Audio Format of output file

                      Alternatively, it can be a custom loudspeaker layout File

                      left or l or 90->left, right or r or -90->right, center or c or 0 ->middle

-exof File          : External orientation trajectory File for simulation of external orientations

-dpid ID            : Directivity pattern ID(s) (space-separated list of up to 4 numbers can be 

                      specified) for binaural output configuration

                      specified) for binaural output configurations

-aeid ID            : Acoustic environment ID (number > 0) or

                      a sequence thereof in the format [ID1:duration1,ID2:duration2...]

                      without braces and spaces, with ':' character separating ID from duration and ',' separating

-g                  : Input gain (linear, not in dB) to be applied to input audio file

-l                  : List supported audio formats

-smd                : Metadata Synchronization Delay in ms, Default is 0. Quantized by 5ms subframes.

-om File            : Coded metadata File for BINAURAL_SPLIT_PCM output format

-om File            : Coded metadata File for BINAURAL_SPLIT_PCM output configuration

-level level        : Complexity level, level = (1, 2, 3), will be defined after characterisation.

                      Currently, all values default to level 3 (full functionality).

-q                  : Quiet mode, limit printouts to terminal, default is deactivated

obj_<int>_relazi=0|1    if 1, obj_<int>_azi is interpreted as a relative modification. default is absolute modification

obj_<int>_ele=<float>   elevation angle in degrees to be applied on object <int>, 0-based indexing

obj_<int>_relele=0|1    if 1, obj_<int>_ele is interpreted as a relative modification. default is absolute modification

obj_<int>_radius=<float>  linear radius to be applied on object <int>, 0-based indexing

obj_<int>_relradius=0|1   if 1, obj_<int>_radius is interpreted as a relative modification. default is absolute modification

obj_<int>_yaw=<float>   yaw angle in degrees to be applied on object <int>, 0-based indexing

obj_<int>_relyaw=0|1    if 1, obj_<int>_yaw is interpreted as a relative modification. default is absolute modification

obj_<int>_pitch=<float>   pitch angle in degrees to be applied on object <int>, 0-based indexing

obj_<int>_relpitch=0|1    if 1, obj_<int>_pitch is interpreted as a relative modification. default is absolute modification

If a parameter is not specified, that parameter is not edited. An empty line in the file corresponds to

not editing any parameter in the item.
