Gold 30

This is a curve with a slow decay at Start  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 by inserting the number FI in a base 30 logarithmic equation.

Medium Rain

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

Default frequency decay sequence was faded out, in the extension of 9 octaves, using Medium Rain sound generator to produce this set of impulse responses

It’s a general-purpose medium 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, 8 Phaser processed impulse files in a total of 288 Impulse files, with the following folder structure:

Examples:

RA G30 A PH 3 Means Medium Rain sound as generator, Gold30 as fall curve, A PH as tone, Phaser as modulator, and 3 seconds of Impulse length.

RA G30 A PH MS 3 The same as previous but with M/S processing.

RA G30 A PH 6 Means Medium Rain sound as generator, Gold30 as fall curve, A as tone, Phaser as modulator, and 6 seconds of Impulse length.

RA G30 A PH Oct 6 Oct means 1 octave up.

The files on the other folders follow the same syntax meanings
