HS066

This is a curve with a medium slow decay at beginning and a  very slow decay at the end. The area of the curve is 40.75% of the full square area (-7.8 dB).

If based on area ratio (current to Linear (50%), it’s RT60 time should be 0.81 of Linear RT60.

This curve was calculated from the Hyperbolic Secant Curve Equation, applying a value of 0.666666 as constant

WN

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

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

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 from A to Bb.

Inside each Tone folder we have  8 clean impulse files, in a total amount of 288 Impulse files, with the following folder structure:

Wave Naming

WN AS HS066 A FS 3  means Frequency Shifted White Noise as generator, Hyperbolic Secant 0.666666 as fall curve, A as Tone and 3 seconds of Impulse length.

WN AS HS066 A FS MS 3 the same as previous but with an M/S building processing

WN AS HS066 A FS 6 means Frequency Shifted White Noise as generator, Hyperbolic Secant 0.666666 as fall curve, A as Tone and 6 seconds of Impulse length.

WN AS HS066 A FS Oct 6 Oct means one octave up

The files on the other folders follow the same syntax meanings
