Astroid

This is a curve with a fast decay at beginning and a slow decay at the end. The area of the curve is 29.85% of the full square area (-10.38 dB FSA).

If based on area ratio (current to Linear (50%), it’s RT60 time should be 0.61 of Linear RT60.

This curve was calculated from the Astroid Curve Equation ( https://en.wikipedia.org/wiki/Astroid )

WN

This collection was made by direct Fall from White Noise of default style Octave Curves.

It’s a general-purpose medium fast 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 has 8 clean impulse files and another 5 folders containing a lot of processed files, in a total of 3132 impulse files, as following:

Dyn contains 5 folders of compressor processed impulses in a total of 60 files

Fx contains 5 folders of effect processed impulses in a total of 60 files

HP Contains 12 High pass processed files

PNL contains 12 Pink Noise Linear processed files

Wide contains two folders of widening processed impulse responses in a total of 24 files
