Bypass, this is how the 50% dutycycle sinewave burst looks like. X-axis shows time in milliseconds, Y-axis
shows linear level in percentage of full scale. Just like a scope.
Fig. 2
A very short preview time combined with a long attack time cause an overshoot at the onstart of the burst. As
the sidechain reacts to the input signal (slowly because of the long attack time) the level of the burst is brought to the
anticipated level.

The preview time is now about three times the attack time, which gives the sidechain a headstart on the audio
signal. The result is a proper limiting without overshoot.

As useful the preview facility in Fig 3 is, it can have an unwanted effect at the release portion. A relatively
short release time causes the release to show up during the last milliseconds of the burst. This because the sidechain
"sees" the "burst off" before the gain stage sees it (preview delay), so the end of the burst gets influenced by the
release.
