170 Chapter 7 Working in the Waveform Editor
Show Realtime Effects
In addition to processing effects, you can apply realtime effects to an audio file project.
The Show Realtime Effects command shows the Effects tab with any realtime effects
applied to the current audio file project. You can apply realtime effects to the project in
the Effects tab, and can automate realtime effect parameters in the Waveform Editor.
To show realtime effects for the current audio file project:
m Choose Process > Show Realtime Effects.
Bounce Realtime to Action
Choosing this command bounces any realtime effects applied to the audio file project,
and the project’s envelopes, to an action in the Actions list, letting you turn these
effects and envelopes on or off, and reorder them in the list.
To show realtime effects and envelopes to an action:
m Choose Process > Bounce Realtime to Action.
Once you bounce realtime effects and envelopes to an action, the realtime effects are
deleted from the project, and the envelopes are reset to their default values.
Some effects, including reverb and delay, add audio that extends past the end of the
file. This is called an effect “tail.” When you bounce realtime effects to an action, if any
of the effects creates an effect tail that extends past the end of the audio file, the file
lengthens to include the effect tail.
Working With Actions
Actions give you an extremely flexible and powerful way to edit audio files in the
Waveform Editor. You can apply an action to an entire file or a selected part of the file,
including applying an action to only one channel of a stereo audio file. You can turn
individual actions on or off and reorder actions in the Actions list, changing the
sequence in which the actions change the audio file. You can adjust action settings
after applying the action, and can flatten actions.
