Neper

 

This is a curve with a very slow decay at Start and a very fast decay at the End. The area of the curve is 60.53 % of the full surrounding square area (-4.36 dB FSA).

If based on area ratio to Linear area, it’s RT60 time should be 1.21 of Linear RT60.

This curve was calculated inserting the Euler number 2.718282 into a base 10 logarithmic equation.

WN

 

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

Basically, used on percussive material as extra slow decay impulse (gate reverb style), or in 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 8 clean impulse files and another folder with 8 phase processed impulse files, in a total of 576 Impulse files, with the following folder structure:

 

Wave Naming

 

WN N_Nep A 3 Means 3 White Noise as generator, Neper as fall curve, A Minor as Tone and 3 seconds of Impulse length.

 

WN N_Nep A MS 3 The same as previous but with M/S building processing.

 

WN N_Nep A 6 Means 3 White Noise as generator, Neper as fall curve, A Minor as Tone and 6 seconds of Impulse length.

 

WN N_Nep Oct A 6 Oct means one octave up.

 

WN PHR SHV6 N_Nep A 3 Means phase processed White Noise as generator, Neper as fall curve, 3 seconds of Impulse length.

 

WN PHR SHV6 N_Nep A MS 3 The same as previous but with an M/S building processing.

 

WN PHR SHV6 N_Nep A 6 Means phase processed White Noise as generator, Neper as fall curve, 6seconds of Impulse length.

 

WN PHR SHV6 N_Nep Oct A 6  Oct means one octave up.

 

The files on the other folders follow the same syntax meaning
