Pre Attack Time

The Pre Attack Time parameter allows you to add a defined amount of “pre-roll” to the

beginning of all Regions created by the Strip Silence process. High threshold values

prevent any amplitudes with slower attack times from being “chopped”. This function is

useful for non-percussive material such as; vocals, wind instruments, strings, and so on.

The units are shown in seconds. The smallest division is one tenth of a millisecond.

Overlaps are permitted—the pre-delayed start point of a Region can extend back to

the end of the previous Region—but only if the threshold value is not exceeded.

Altering the Pre Attack Time has no effect on the Anchor position, or the absolute

position of the audio data on the sequencer time axis.

Post Release Time

Post Release Time allows you to define an automatic release time for the end points of

all Regions. The units are shown in seconds. The smallest division is one tenth of a

millisecond.

You can use this function to avoid cutting off amplitudes that fade out gradually

(particularly if you have set a high threshold value). As examples; cymbals, open hi hats,

snares with long reverbs, vocals, and so on

The Post Release Time parameter does not allow overlaps. This means that the Region’s

end point cannot extend beyond the start point of the following Region.

Adjusting the Post Release Time does not affect the Anchor position, or the absolute

position of the audio data on the sequencer time axis.

Search Zero Crossings

If the Search Zero Crossings option is active in the Strip Silence window, the Region start

and end points are always automatically snapped to the nearest waveform zero

crossings.

Click the check box, to toggle the automatic positioning to zero crossings on and off.

Other Strip Silence Functions

Replacing a Region in the Arrange

If you are editing a Region being used in the Arrange window, you can open a dialog

window by clicking OK in the Strip Silence window (or by pressing Return).

If you want to replace the Region in the Arrange with Regions created by the Strip

Silence function, click Replace or press Return. This ensures that the relative timing of

the individual audio segments remains unaltered. Listen to the results, and if you’re

unsatisfied, Undo it!

If you only want the new Regions to appear in the Audio window, click No. You can

then drag them individually into the Arrange window, in the usual way.
