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

SQF

This collection was made by direct Fall from White Noise of default style Octave Square 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 8 clean impulse files more 4 folders with 8 variable Q factor processed impulse files each, in a total of 1440 Impulse files, with the following folder structure:
