Witch of Agnesi (Euler)

This is a curve with a  slow decay at beginning and a  medium fast decay at the end. The area of the curve is 37.74% of the full square area (-8.46 dB).

If based on area ratio (current to Linear (50%), it’s RT60 time should be 0.75 of Linear RT60. time

This curve was calculated from the Witch of Agnesi  Equation with the Euler number (2.7183) as constant

WPN

This collection was made by direct Fall from a mix of White and Pink Noise of default style Octave Curves.

It’s a general-purpose fast 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 8 impulse files covering 2 octave central frequency extension.

Total of 288 impulse files. with the following folder structure:

Examples of f:

• WPN WANep A 3 means White and Pink Noise as generator, Witch of Agnesi (Euler) as fall curve, A Minor as Tone and 3 seconds of Impulse length.
• WPN WANep A MS 3 the same as previous but with an M/S building processing
• WPN WANep A 6 means White and Pink Noise as generator, Witch of Agnesi (Euler) as fall curve, A as Tone and 6 seconds of Impulse length.
• WPN WANep A Oct 6 Oct means one octave up

The files on the other folders follow the same syntax meaning
