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 WND

Major and Minor chords were faded out, in the extension of 9 octaves, using White Noise with delay generator.

Equal frequency relations were applied thru the notes of the chords to produce this set of impulses.

It’s a general-purpose soft slow 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 Ab).

Inside each Tone folder, a Minor, a Major and a Mix folder.

Inside each Mix folder a Major and a Minor folder, all of them having 8 impulse files.

In the Mix folder a different relation between the notes of the chords were used

A total of 1152 Impulse files distributed according to the following folder structure:
