SC033

This is a curve with a fast decay at beginning and a  slow decay at the end. The area of the curve is 33.74% of the full square area (-9.44 dB FSA).

If based on area ratio (current to Linear (50%), it’s RT60 time should be 0.67 of Linear RT60.

This curve was calculated from the Semicubical Parabola Curve Equation

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 86 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 pan processed impulse files, in a total of 576 Impulse files, with the following folder structure:

Examples:

• SQF WND SC033 A 3 means Square Fall White Noise with delay as generator, Semicubical 0.333333  as fall curve, A as Tone, and 3 seconds of Impulse length.
• SQF WND SC033 A MS 3 the same as previous but with an M/S building processing
• SQF WND SC033 A 6 means Square Fall White Noise with delay as generator, Semicubical 0.333333 as fall curve, A as Tone, and 6 seconds of Impulse length.
• SQF WND SC033 A Oct 6 Oct means one octave up
• SQF WND SC033 A PAN 3 means pan processed Square Fall White Noise with delay as generator, Semicubical 0.333333 as fall curve, 3 seconds of Impulse length.
• SQF WND SC033 A PAN MS 3 the same as previous but with an M/S building processing
• SQF WND SC033 A PAN 6 means pan processed Square Fall White Noise with delay as generator, Semicubical 0.333333 as fall curve, 6 seconds of Impulse length.
• SQF WND SC033 A PAN Oct 6 Oct means one octave up

The files on the other folders follow the same syntax meaning
