Importing frd & zma from VituixCAD - inability to display waterfall plots

[Panash]

Hi,

I've imported frd & zma files from VituixCAD and the magnitude and impedance display fine but the waterfall display is blank. Ideas?

Work flow
REW measurements -> frd, zma -> VituixCAD -> crossover design -> zma & frd -> REW

(group delay works by the way but none of the others do)
Unfortunately VituixCAD doesn't have a waterfall plot.

Imported responses don't produce an impulse response, which is required for waterfalls and spectrograms. You can force an IR to be generated for an FRD Import by using the Generate minimum phase action, which will make an IR from the imported response as well as generate a minimum phase IR.

I might need some help on this one please. The help gives an example script file which needs executing somehow and the help is a bit light on what the parameters mean.

However VituixCAD will export an impulse wav file which will generate a waterfall plot. This might be the easiest solution.

It must be pushing the numerical limitations of the system I would have thought.

Are you referring to the API help? The API is a way to access REW features programmatically, it would be a bit redundant to duplicate the rest of the REW help in the API help file. Here is the help for Generate minimum phase.

Almost certainly.
