/**
* MPEG-H 3D audio info.
*
* MPEG-H content is assumed to be provided in the form of an MPEG-H
* 3D Audio Stream (MHAS). MHAS is a lightweight bitstream format that
* encapsulates MPEG-H 3D Audio frames along with associated metadata.
* It serves a similar role to the Annex B byte stream format used for
* H.264, providing framing and synchronization for MPEG-H frames.
*
* MPEG-H is documented in the ISO/IEC 23008-3 specification.
* MHAS is specified in ISO/IEC 23008-3, Clause 14.
*
* Note that unlike other formats, this one does not specify a channel
* count. This is because MPEG-H is entity-based; it contains multiple
* entities of different types (channel beds, audio objects etc.) which
* do not map 1:1 to channels. The channel amount is determined by
* decoders instead, based on the audio scene content and the target
* playback system.
