Attack; Auto Fast Attack - elysia alpha compressor Manual

Attack

Here a burst signal (a sine tone that is boosted by 12 dB for a period of 100 ms) is used to demon-
strate the effectiveness of the attack controller. The different curves show how fast this level jump
is reduced by 4 dB. On fast settings the reduction takes only a few milliseconds, on longer settings
the reduction does not only take longer, but it is also smaller. Therefore the amount of gain reduc-
tion is always higher on fast attack settings than on longer settings.

Auto Fast Attack

Utilizing a burst signal again, this diagram shows a comparison between a normal attack time of
50 ms (dark curve) and the later added Auto Fast function (light curve). This reveals how fast this
circuit reacts: Even the first waves of the burst are already reduced by 2.3 dB. The whole gain re-
duction now happens much faster, too. Note: This function starts working at -3 dB; on lower gain
reduction values the changes in dynamics are too small to trigger it accurately.
