Kappa

This is a curve with a very fast decay at beginning and a  slow decay at the end. The area of the curve is 34.08% of the full square area (-9.35 dB).

If based on area ratio (current to Linear (50%), it’s RT60 time should be 0.68 of Linear RT60. time

This curve was calculated from the Kappa Curve Equation

WN

This collection was made by direct Fall from White 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 has 12 clean impulse files (3 Octaves) and another 5 folders containing a lot of processed files, in a total of 1800 files, as following:

Dyn contains 2 folders of compressor processed impulses in a total of 24 files

Fx contains 12 files of effect processed impulses

HP Contains 12 High pass processed files

PNL contains 12 Pink Noise Linear processed files

Wide contains 3 folders of widening processed impulse responses in a total of 2700 files

Examples:

• WN KAP A 3 means White Noise as generator, Kappa as fall curve, A as Tone and 3 seconds of Impulse length.
• WN KAP A MS 3 the same as previous but with M/S building processing.
• WN KAP A 6 means White Noise as generator, Kappa as fall curve, A as Tone, and 6 seconds of Impulse length.
• WN KAP A Oct 6 Oct means one octave up.
• WN KAP A DOct 6 DOct means one octave down.

The files on the other folders follow the same syntax meaning
