What uses ambisonics in opus?
It appears to have something to do with multi-channel (surround) encoding. No idea what it brings.
In theory, there is no difference between theory and practice. In practice there is.

It is a surround format that doesn't rely on fixed speaker positions or the number of speakers. The closest thing I can think of is something like Dolby Atmos.
For example with a normal 5.1 surround audio track you need 5.1 speakers to hear the how it is intended. Then when you use headphones there is not information in the 5.1 audio track to determine how to correctly represent the sound field around the listener in stereo.
With Ambisonics you would get the correct surround sound no matter the amount of speakers. The Ambisonics B-format gets rendered to headphones or to the amount of speakers you have.
It is very useful for Virtual Reality.
