Multichannel sources are virtual sources that are composed of multiple mono sources. Their layout can be manually adjusted, but will correspond by default to ITU standards.
Multichannel sources settings are similar to mono sources settings, except for positionning parameters, described below.
Other 3D parameters are similar to mono sources 3D Parameters.
Use the Channels Parameters window to the the position, gain and delay alignment of the individual channels of a Multichannel object.
This field indicates which input is connected to each channel composing the Multichannel object. If you need to connect a channel to an other input, use the Routing view.
If your Multichannel is set to an other distance, the resulting distance of the channels will be multiplicated by that AED Distance.
Gain & Delay correction#
The gain and delay corrections allows you to time-align and level-align each channel individually.
Three modes are available for both gain and delay correction, and can be selected from the two drop-down menus at the top:
- It is the default setting. This will disable the gain or delay alignement.
- The manual mode will enable manually setting the gain or delay values.
- Auto mode will let HOLOPHONIX compute the gain and delay values for a perfect phase and level alignement at the center of the Multichannel object.
- Gains and delays are computed as if all the channels were placed on a circle or a sphere. By evaluating the distance between the virtual position on a circle and the real object position, HOLOPHONIX determines the delay and gain attenuation.
- Channels that are the closest to the center will receive a maximum delay and gain attenuation, whereas the farmost channels will receive no delay or gain attenuation.
