Hi everyone!
I'm blocked for already a couple of days on a problem regarding the lecture of a .fcf filter file.
Designing a parametric EQ for shaping a simulated frequency response from audio sound, I need to store a multi-stage filter in a folder for later purposes. This part is complete and working properly. I use the fcfwrite function.
function SaveFilter_Callback(hObject,eventdata,handles)
Hd=getappdata(hObject,'Hd');
prompt = {'How do you want to call the designed multi-stage filter?'};
dlg_title = 'Save the parametric Filter';
num_lines=1;
def = {'sf'};
newname = inputdlg(prompt,dlg_title,num_lines,def);
if isempty(newname)==0
newname=cell2mat(newname);
assignin('base',newname,Hd);
end
fcfwrite(Hd,newname);
fileID=(strcat(newname, '.fcf'));
movefile (fileID, 'paraEQFilter');
However, I'm unable to read the file back as I didn't found an opposite function of fcfwrite. Apparently, there isn't a fcfread function.
My questions are:
How can I read the *.fcf file in order to get the filter in the workspace?
If not possible, how can I store a multi-stage direct-form I filter and get it back?
