1. Broadcast Presets

You can use the broadcast presets menu to edit the broadcasting parameters.

This guide is protected under copyright law

Page 16

Orah 4i User Guide v1.2.0

You can choose an existing preset, delete the selected custom preset, or create a new one.

If you modify an existing preset, you will be able to update, save as a new preset or cancel. The default preset (local-preview-server) can not be deleted. This preset can be used to stream to the box internal server. For more detail you can see our tutorial:

http://support.orah.co/hc/en-us/articles/115000034264-How-to-setup-a-4K-preview

■ RTMP endpoint configuration

■ Enter the correct RTMP server URL to broadcast the RTMP stream to. The system supports any service capable of ingesting RTMP.

■ Enter the stream key as configured on your server.

For more security when broadcasting, you can tick the “use RTMP authentication” box. The username and password to fill in in the RTMP configuration are those defined in your CDN configuration.

You can also change the encoding of the video you will stream.

■ Encoding - to define how the video is compressed and streamed.

■ H264 Profile: to change the compression quality.

■ High (recommended)

■ main

■ baseline

Generally High profile offers the most bandwidth efficient compression for streaming. Main and Baseline can be useful if you have specific device or server compatibility requirements. For more details about profiles : click here.

■ Max Bitrate in Kbps: the number of kilobits per second. This parameter defines the video compression. It affects the general quality of the image. The minimum is 2500 and the maximum is 50000. YouTube’s recommendation for 4k streamed video is between 13000 Kbps - 30000 Kbps. Do not exceed the upload bandwidth of your internet connection, to avoid packet losses during the upload.

The level is the result of the resolution, H264 profile and the bitrate.

Save your changes to a new profile or update one of your existing profiles.

Audio

I. Audio sources

By clicking on the “Audio” button on the bottom left of the interface, the audio settings display. It can take 3 to 5 seconds for the modifications to be applied. This is due to the streaming protocol we are using (HLS).

● There is two ways to capture the sound from the camera: stereo and ambisonic.

● Stereo: The preview, the broadcast and the record are in stereo.

● Ambisonic: The VR preview, the broadcast and the record are in ambisonic sound.

Please note that the equirectangular preview is always in stereo, no matter which audio source is selected.

When the camera source is selected, the gain slider displays. The gain permits to change the sensibility of the microphone (the value ranges from -12 to +67.5). The higher the gain, the more sensitive the microphones.

This guide is protected under copyright law

Page 26

Orah 4i User Guide v1.2.0

Using line-In (stereo): You can connect an external microphone or a smartphone/tablet/mp3 on the box via the frontal jack 3.5.

Note: The sound may not be synchronized with the video. To reach a perfect synchronization, you can tweak the delay slider(value ranging from -1sec to +1sec). If the sound comes later than the video, you should decrease the delay value and vice versa.

II. External USB Cards

Orah v1.2.0 release adds support for professional USB audio cards.

We currently support two cards: Focusrite Scarlett 2i2 et Scarlette 18i8.

We will list supported cards as we collect feedback. Any USB audio class compliant device is expected to detected and work similarly. If you have a different USB audio card, we encourage you to test it and tell us about it.

1.Using USB audio cards

Hot plugging / unplugging of the card is not supported :

● USB audio card must be plugged in before boot in order to be detected

● USB audio card must not be removed while Orah 4i is running

● Multiple USB audio cards can not be used simultaneously

When the audio card is detected, it will appear as an audio source in the audio settings.

This guide is protected under copyright law

Page 27

Orah 4i User Guide v1.2.0

When the audio card is selected, it is used as audio source for preview, broadcasting and recording.

2. Channel layout

a.Mono

Mono channel layout is not supported.

b.Stereo

When selecting stereo audio, the first two channels of your USB audio card will be used as Left and Right channels.

c.First order ambisonic (4 channels)

USB audio cards providing at least 4 channels of audio will be listed with an option to ingest ambisonic. When ambisonic is selected, the first 4 audio channels of you device will be used as audio source for audio passthrough.

The expected audio signal should be in AmbiX format: ACN channel layout & SN3D normalization.

See also : Ambisonic audio

Note : the provided ambisonic audio signal should be aligned with the video. Orientation adjustments and stabilization applied to the video, are not applied to the audio soundfield.

Page 28

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.
