Hello, list. I'm trying to implement the filters from this book https://www.discodsp.net/VAFilterDesign_2.1.0.pdf, which are great, but I'm having some issues getting the right design in Faust.
I'm trying to implement the diagram 3.31 from page 77. It is a 1p1z LP with zero-delay feedback design. In PD, that was fairly easy because you instantiate a delay-line-write object as the input of the state of the filter, and the corresponding D-L-read objects to take the output and send it wherever is needed, either the feedforward or feedback paths. With the core syntax I'm finding it difficult to handle both FF and FB paths with one wire/variable, whereas with the latrec expressions there seems to be an extra delay in the DSP which changes the transfer function. If you could provide insights on how to implement the filter both with the core syntax and the latrec expressions that would be great. Thanks for your help, Dario
