Zylia sources allow inputting to HOLOPHONIX the direct output stream of the HOA microphone "Zylia® ZM1". Check the section below for parameters explanation. If you allready transcoded your Zylia recording to standard HOA stream, use an HOA Stream source to input the signal to HOLOPHONIX. Zylia sources are only intended to receive the direct output of the microphone.
Because Eigenmike and Zylia are 'audio stream' type of sources (that has no spatial position), they are not associated with an object in the 3D VENUE view.
All parameters are similar for all sources except for the parameters below. Check the sources 'Audio Parameters' section.
The Reverb level sends the W omnidirectional channel of the Ambisonic stream to the reverberation bus. There is no early and cluster simulation for Ambisonic sources.
Choose between the four HOA encoding methods. Each method corresponds to various techniques from the latest developments in scientific works concerning this specific task of transcoding audio signals coming from a microphone array, to a Higher Order Ambisonics stream.
We recommend using Method 1.Method 3 and Method 4 are very CPU intensive.
The 'REGULARIZATION' parameter aims at adapting the dynamics of the filters used to encode the microphone array to HOA. Changing its value will have an effect on the ratio between, on one hand, the precision of the localization, and on the other hand, the tone and timber quality, as well as the signal-to-noise ratio.
When changing the value, new filters will be computed. It requires a small calculation time.
This setting is on only available for Method 1.
Use HOA Order to decrease the contribution of the components of each order in the encoded HOA stream.
