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).

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 )

3 SEQ STR TRP

3 SEQ means that 3 groups of Major and Minor chords were tremolo processed and after faded out in a slow regular triplet decay

It’s a general-purpose fast decay impulse, for instruments, or any electronic music effect

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 Bb).

Inside each Tone folder, 2 folders Major and Minor, having 16 Impulse files each, in a total of 1152 Impulse files, with the following folder structure:

Wave Naming

3SEQTWN AST STR TRP A Min 3 means 3 SEQ White Noise as generator, AST as fall curve, A Minor as Tone and 3 seconds of Impulse length.

3SEQTWN AST STR TRP A Min MS 3 the same as previous but with an M/S processing.

3SEQTWN AST STR TRP A Min 6 means 3 SEQ White Noise as generator, AST as fall curve, A Minor as Tone and 6 seconds of Impulse length.

3SEQTWN AST STR TRP A Min D2Oct 3 D2Oct means 2 octaves down.

3SEQTWN AST STR TRP A Min DOct 3 DOct means one octave down.

3SEQTWN AST STR TRP A Min Oct 3 Oct means one octave up.

The files on the other folders follow the same syntax meanings
