Log 30 Gold

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 inserting the number FI in a base 30 logarithmic equation.

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

Waterfall (WFA)

Default frequency decay sequence was faded out, in the extension of 9 octaves, using frequency shift processed Waterfall 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 clean files and one folder with eight Tremolo processed wave files, in a total of 576 Impulse files, with the following folder structure:
