Gold

This is a curve with a slow decay at beginning and a fast decay at the end. The area of the curve is 46.07% of the full square area (-6.73 dB).

If based on area ratio (current to Linear (50%), it’s RT60 time should be 0.92 of Linear RT60.

This curve was calculated inserting the number FI in a base 10 logarithmic equation.

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

WPN

This collection was made by direct frequency Fall from a mix of White and Pink Noise of default style Octave Curves.

It’s a general-purpose slow decay impulse, for vocals and instruments, or any electronic musical source.

Inside each folder 12 tone folders (A to Bb).

Inside each tone folder we have 8 impulse files, in a total of 288 Impulse files, with the following structure:
