Sorry for this one but... I downloaded winpcd and want to start designing a crossover for "x" speakers, where do I get the frd and zma files?

Paul Carmody made a guide that should help you make your own frd and zma files from graphs provided by the manufacturer of "x" speakers.

I hope this helps.

I would like to know if PCD file format in importing ZMA and FRD files is sensitive to
- if the field value decimal separator is comma ( , ) or dot ( . ) or
- if the different value´s field separator can be one or several blanks or tabulator or ;
- or if computer´s regional settings have impact to success of importing the FRD & ZMA file

I had difficulties in testing the imports and frequency and impedance plots did not look like good at all.

Other topic is, that are the old pcd excel version test/training cases possible to use with the latest PCD win version ?

Commas cannot be used for the decimals. Some measurement systems export files as CSV, comma separated values. Commas, one or more spaces or tabs (white space) are fine for the field separators.

With regard to regional, I'm not aware of issues. Regional settings shouldn't affect files, what does is the content of the files.

You should be able to import old PCD project files, but they will be missing a lot of data that has been added for WinPCD. Try importing a project file, then "fill in the blanks", so-to-speak.
