Get information about the audio track currently set. null if no audio track is enabled right now.

If an audio track is set and information about it is known, this method will return an object with the following properties:

• id (Number|string): The id used to identify this track. No other audio track for the same Period will have the same id.

  This can be useful when setting the track through the setAudioTrack method.

• language (string): The language the audio track is in, as set in the Manifest.

• normalized (string): An attempt to translate the language property into an ISO 639-3 language code (for now only support translations from ISO 639-1 and ISO 639-3 language codes). If the translation attempt fails (no corresponding ISO 639-3 language code is found), it will equal the value of language

• audioDescription (Boolean): Whether the track is an audio description of what is happening at the screen.

• dub (Boolean|undefined): If set to true, this audio track is a “dub”, meaning it was recorded in another language than the original. If set to false, we know that this audio track is in an original language. This property is undefined if we do not known whether it is in an original language.

  • id (string): The id used to identify this Representation. No other Representation from this track will have the same id.

  • bitrate (Number): The bitrate of this Representation, in bits per seconds.

  • codec (string|undefined): The audio codec the Representation is in, as announced in the corresponding Manifest.
