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

3 SEQ ISO

3 SEQ means that 3 groups of Major and Minor chords were faded out in an equal energy per frequency band mode

It’s a general-purpose fast decay impulse, for vocals and instruments, or any electronic music effect

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, 2 folders Major and Minor,

Additionally two folders of processed impulses per tone folder were added.

A Wide version and a Reverse processed version of the Iso impulses in a total of 3456 Impulse files, with the following folder structure:

Wave Naming

3SISOWN SC044 A Min Clear 3 means 3 SEQ ISO White Noise as generator, Semicubical 0.444444 as fall curve, A Minor as Tone, Clear as sound and 3 seconds of Impulse length.

3SISOWN SC044 A Min Grey 3 means 3 SEQ ISO White Noise as generator, Semicubical 0.444444 as fall curve, A Minor as Tone Grey as sound and 3 seconds of Impulse length.

3SISOWN SC044 A Min Clear MS 3 the same as previous but with M/S processing.

3SISOWN SC044 A Min Grey MS 3 the same as previous but with M/S processing.

3SISOWN SC044 A Min Clear 6 means 3 SEQ ISO White Noise as generator, Semicubical 0.444444 as fall curve, A Minor as Tone, Clear as sound and 6 seconds of Impulse length.

3SISOWN SC044 A Min Grey 6 means 3 SEQ ISO White Noise as generator, Semicubical 0.444444 as fall curve, A Minor as Tone, Grey as sound and 6 seconds of Impulse length.

3SISOWN SC044 A Min Clear Oct 3 the same as above but  one octave up.
