|In Ambisonics mode OpenMixer can decode an incoming Ambisonics encoded audio stream.
Select the input source1. Press any of the source buttons to select an input source, the button will light up and that source will be selected.
Activate Ambisonics mode2. Press the Ambisonics button to enable the Ambisonics decoding mode.
Set input level3. In Ambisonics mode only the first fader is active. Move the fader to set the input level for all channels in the selected source. If you move any other fader it will automatically reset to 0 after a couple of seconds.
Select the Ambisonics Decoder4. OpenMixer has several decoders. Press the Ambisonics decoder button for the decoder you want to be active. Current choices include:
Master level5. This control is redundant but can be used to set the master level of the input source. Press the knob to reset the level to -10dB.
Input ChannelsThe ordering of the channels for the inputs is fixed as follows:
The decoders assume FSM encoding.
See this page for the meaning and equations that correspond to each component of an Ambisonics stream.
The first 8 channels can contain a mixed order stream (3rd order horizontal and 1st order vertical), the next 8 channels add full periphonic 3rd order components.
