Just being nosy: where does this 86% for the attack time stem from? Usually it's 63% = 1 - 1/e. Is it 1 - 1/e^2 here or something completely different and why? |

Quote: Because increasing time has a diminishing effect on gain for compressors, it is practical to specify attack as the time required for gain to settle to a defined percent of final value. Typical are 86% or 95% of the final value.

I actually have no idea. I read descriptions of these numbers being more or less a standard so I used them... |

Now I'm stunned. But ST is still using an exponential function, i.e. to reach 86% needs two times as long as reaching 63%, correct? |

Probably, yes. If you're not using things like Inertia. |
