Previewing effects in Edit View
Many dialog boxes provide a Preview button for previewing effects in real time. This means
that you can monitor the processed signal before applying the effect to the waveform. The
preview feature updates in real time, meaning that changes you make to effect settings while
in the dialog box for that effect become audible immediately, while the audio is playing.
Keep in mind that your system’s performance affects the preview feature. On slower systems,
some effects may tend to break up or skip during preview. In Multitrack View, the preview
is not necessary, as effects are used nondestructively. Basically, every effect in the Multitrack
View is in preview all the time. For more information on the differences between destructive
and nondestructive editing, see “About using Edit View and Multitrack View” on page 10.
In Edit View, you can add an optional preroll or postroll amount to the duration of the
preview. This is especially useful when previewing effects for small ranges and marquee
selections because it lets you hear how the in and out transitions are affected by the effects
settings.
To preview effects in real time:
1 Click the Preview button to start playing the audio.
2 Adjust the effect settings as desired.
3 To compare the original audio to the processed audio, select and deselect the Bypass
option. When the option is selected, you hear the original audio; when the option is
deselected, you hear the processed audio.
4 When you’re satisfied with the settings, click Stop.
To add a preroll and postroll duration to a preview:
1 In Edit View, right-click the Play button or the Play To End button in the transport
controls, and choose Preroll And Postroll Options.
2 In the Effects Preview section of the Preroll And Postroll Options dialog box, enter
durations for the preroll and postroll, and click OK.
