Astroid

This is a curve with a fast decay at Start 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:

3 Ocean

Major and Minor chords were faded out, in the extension of 9 octaves, using 2 Ocean sounds in direct sum DIR, and 1 direct and other reversed REV 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 DIR and REV (as explained before) then each folder in 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, a Minor and a Major folder with 16 Impulse files, in a total of 2304 Impulse files, with the following folder structure:

Examples:

3OCX2 AST A Min 3 means 2 Ocean sounds as generator, Astroid as fall curve, A Min as Tone and 3 seconds of Impulse length.

3OCX2 AST A Min MS 3 the same as previous but with an M/S processing.

3OCX2 AST A Min 6 means 2 Ocean sounds as generator, Astroid as fall curve, A Min as Tone and 6 seconds of Impulse length.

3OCX2 AST A Min Oct 6 Oct means 1 octave up.

3OCX2 AST A Min DOct 6 DOct means 1 octave down.

3OCX2 AST A Min D2Oct 6 2DOct means 2 octaves down.

The files on the other folders follow the same syntax meanings
