SC044

This is a curve with a medium fast decay at beginning and a  very slow decay at the end. The area of the curve is 40.4% of the full surrounding square area (-7.89 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 Semicubical Parabola Curve Equation, applying a value of 0.444444 as constant

SMO

9 frequency bands were faded out, in the extension of 9 octaves, using 3 different Smoothed White Noise generators with delay to produce this set of impulses

It’s a general-purpose very soft slow decay impulse, for strong 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 Ab).

Inside each Tone folder 3 folders containing impulses of different source types.

In each one we have 8 Impulses, in a total of 864 Impulse files, with the following folder structure:
