Hi,
I imported in REW the following impulse response :
0 0.16667 -0.66667 1.00000 -0.66667 0.16667 0
It's the impulse response of a transfer function having four zeros at unity.
If I compute its Fourrier transform in Octave and draw a loglog graph, I got the expected result :
A constant 24db/o slope going to -infinity at 0Hz.
But in REW I got that :
Where do this zero at 800Hz come from ?
I tried different parameters without any changes ....
