ADAU1761 SigmaStudio 4.1, detail information about Fixed / Beam Forming Designer

I use the ADAU1761 with the Sigma Studio ver.4.4.

In the Tool Box, we can find two beam forming function

 - Adaptive / Adaptive Beam Forming Algorithm

 - Fixed    / Beam Forming Designer

 

But in the on-line help, they are not included.

On the Wiki, I could find below. Are there any documents or information about  the "Fixed   / Beam Forming Designer"?
