Orah 4i - Ambisonic Audio

Orah 4i User Guide v1.2.0
Ambisonic audio
Orah 4i can capture ambient audio in first order (4 channels) ambisonic, thanks to it's advanced
audio processing and specifically positioned microphones.
It delivers spatial audio in AmbiX format (ACN channel layout and SN3D normalization).
I.Spatial audio preview in the browser
Spatial audio can be previewed in the control app using the VR preview. It is enabled
automatically when you configure Orah 4i with an ambisonic audio source.
Note: Ambisonic playback will fail on iPhones and iPads, as iOS does not currently support HLS
preview with 4 channels of audio. Internet Explorer 11 does not support Ambisonic neither.
In those cases an icon is displayed on the upper-right of the Orah Webapp.
II. Ambisonic recording
The recorded MP4 files embed spatial media metadata for spatial audio playback on platforms
that support it, such as Youtube and Facebook.
The metadatas provide the description of the ambisonic format for these platforms to playback
the audio accurately.
III. Ambisonic broadcasting
Orah 4i is also capable of broadcasting spatial audio. The broadcasted stream will yield 4
channels of AmbiX formatted audio.
In the case of ambisonic audio broadcasting, no metadata are passed to configure the player or
CDN.
