Witch of Agnesi (2)

This is a curve with a  slow decay at beginning and a  fast decay at the end. The area of the curve is 34.52% of the full surrounding square area (-9.24 dB FSA).

If based on area ratio (current to Linear (50%), it’s RT60 time should be 0.69 of Linear RT60. Time. This curve was calculated from the Witch of Agnesi  Equation with 2 as constant

Inside each tone folder we have 4 folders, each one with 12 files of different building type impulses, as follows:

I constant slow fall of frequency bands

II constant fast fall of frequency bands

III progressively faster fall of frequency bands

IV progressively slower fall of frequency bands

Total of 1728 Impulse files. with the following folder structure:
