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

WPN

This collection was made by direct Frequency Fall from a mix of White and Pink Noise

It’s a general-purpose medium decay impulse, for vocals and instruments, or any electronic musical source.

The collection is divided into  44.1 kHz 24 bit, 48 kHz 24 bit and 96 kHz 24 bit folders. Inside each folder 12 tone folders (A to Bb).

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:

Wave Naming

WPN WA2 I A 3 means White and Pink Noise as generator, Witch of Agnesi (2) as fall curve, A as Tone, and 3 seconds of Impulse length.

WPN WA2 I A MS 3 the same as previous but with an M/S building processing

WPN WA2 I A Oct 6 means White and Pink Noise as generator, Witch of Agnesi (2) as fall curve, A as Tone, and 6 seconds of Impulse length.
