    Hi John,

    Glad you got it working. We were about to suggest exactly what you did with adding a phase column. There’s an option, on the FIR Designer Target tab, to either ignore the phase and use magnitude only.

    For TXT and CSV import, a file with:
    – 2 columns is treated as an time impulse response (with 1st column as a timestamp and the 2nd column the impulse response coefficients).
    – 3 columns is treated as frequency (Hz), magnitude (dB) and phase (deg).
    – 4 columns is treated as per 3, with the 4 column as coherence (between 0 and 100 %)

    Best regards,
