Gold 30

This is a curve with a slow decay at beginning and a fast decay at the end. The area of the curve is 39.85% of the full square area (-7.99 dB FSA).

If based on area ratio (current to Linear (50%), it’s RT60 time should be 0.8 of Linear RT60. time

This curve was calculated inserting the number FI in a base 30 logarithmic equation.

FI is the Golden Ratio 1.61803399…. (X^2 = X+1)

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 each.

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

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

Wave Naming

3WND G30 A Min D2Oct 3 means White Noise with delay as generator, two octaves down Gold30 as fall curve, A Min as Tone and 3 seconds of Impulse length.

3WND G30 A Min D2Oct MS 3 the same as previous but with M/S processing

3WND G30 A Min D2Oct 6 means White Noise with delay as generator, two octaves down Gold30 as fall curve, A Min as Tone and 6 seconds of Impulse length.

3WND G30 A Min DOct 6 DOct means 1 octave down

The files on the other folders follow the same syntax meanings
