    Open Live Script

    Create a SOFA object following the SimpleFreeFieldHRIR convention.

    s = sofaconvention("SimpleFreeFieldHRIR");

    Generate mock impulse response data to store in the file. Set the number of measurements M to two and set the impulse response length N to 1024. The number of receivers R is two, corresponding to two ears. Use the fir1 function to create arbitrary FIR filters for the impulse response measurements.

    M = 2;
N = 1024;
R = 2;

IR = zeros(M,R,N);
IR(1,:,:) = [fir1(N-1,0.1);fir1(N-1,.2)];
IR(2,:,:) = [fir1(N-1,0.15);fir1(N-1,.25)];

    Store the measurements in the SOFA object. Modify one of the metadata properties.

    s.Numerator = IR;
s.Comment = "This SOFA file contains mock FIR data.";

    Write the object to a file named myFile.sofa.

    write(s,"myFile.sofa");
