    The data across the formats is effectively identical, with some caveats for WAV.

    CSV(row) has FIR coefficients formatted as text in a row.
    0.0010, -0.07, 1.0, 0.03 …..

    CSV(column) has FIR coefficients formatted as text in a column
    0.0010,
    -0.07,
    1.0,
    0.03

    WAV uses 24 bit WAV files to store the coefficients. WAV does quantize the data to 24 bit depth, but still has an effective range of > 130 dB. WAV also clips coefficients that are > 1.0 or < -1.0. But “FIR Creator EX” will give a warning if your FIR filter coefficients are outside -1.0 to 1.0 and you are trying to save as WAV.

    I’d recommend using one of the CSV formats.
