channels	integer	The number of audio channels. minimum: `1` maximum: `16`
bitrate_kb	number	The audio bitrate in kilobits per second. minimum: `1` maximum: `1024`
layer_id	string	This indicates which Layer this tracks belongs to. For example, this allows bundling one video layer and multiple audio layers with same bitrates but different languages.
layer_affinities	array	This indicates which other layers this layer can be combined with. For example, to combine audio and video layers.
frame_rate	enum `auto` `23.976` `24` `25` `29.97` `30`	The frame rate to be associated with the audio output.
sample_rate	integer string	The audio sample rate in Hz. Currently, valid only for Dolby Atmos master conversion and xHEAAC encoding. Sample rate should be provided as integer. xHEAAC encoding supports 'auto' configuration.
downmix_config	enum `off` `mono` `stereo` `5.1`	The channel configuration to target when downmixing.
surround_90_degree_phase_shift	boolean	`*****`
surround_3db_attenuation	boolean	`*****`
language	string	The language tag to include in the AC-4 stream, for example "eng" or "eng-US". Default is empty. The ISO 639-2 and ISO 639-3 special language codes MIS, MUL, UND, and ZXX, and the language code QAA are not allowed. If the tag is a 3 letter code according to ISO 639-2 that is not compliant to BCP 47, the tag will be converted to its 2 letter equivalent according to ISO 639-1.
warp_mode	enum `normal` `warping` `pl2x` `loro`	Edit warpMode metadata in an ADM BWF file. When this option is used, all other target convertion options are ignored. Format change is not possible.
iframe_interval	number	I-frame interval expressed in seconds. minimum: `0.5` maximum: `10`
ipf_interval	number	Immediate Playout Frame interval expressed in seconds. minimum: `1` maximum: `60`
stream_id	integer	Allows for specifying the stream identifier. Value 0 (default) means that the stream identification will not be signaled. The assigned value should be unique within the adaptive set. Values: [0-65535]. maximum: `65535`
filters	array	`*****`
source	array	Mapping audio tracks.
