Adding Audio Effects
You can use audio effects, or plug-ins, to improve the quality of the audio in a production or to create special artistic effects. Vegas®
Pro software supports a variety of DirectX® and VST plug-in effects from both Sony Creative Software Inc. and third-party vendors.
Using audio effects
There are four ways to use audio effects: event effects, track effects, bus effects, and assignable effects. The combination of these
various methods of applying audio effects is important to the final mix of a project. For more information, see Audio signal flow on
page 35.
• Event effects are applied to events on the timeline.
• Track effects are applied to all events in a single track.
• Bus effects are applied to a bus (including the Master bus). When you add plug-ins to a bus, the tracks that are assigned to the
bus are processed by the plug-ins. Since multiple tracks can be assigned to a single bus, using bus-level audio effects is an
efficient method of applying carefully customized chains of audio effects to multiple tracks. If plug-ins are assigned at the track
level, the track’s signal flows through the track’s plug-ins before the bus plug-ins.
• Assignable effects allow you to send various levels of multiple tracks to a single effect chain. Like busses, these controls reside
in the Mixing Console and support plug-in chains. In addition, assignable effects outputs can be routed to busses. Click the
Insert Assignable FX button (
) in the Mixing Console to add an assignable effect chain to your project. For more
information, see Using FX send (assignable effects) channel strips on page 221.
Important: Be aware that using non-in-place plug-ins (such as Time Stretch, Pitch Shift without preserving duration, and some
Vibrato settings) will cause audio to play out of synchronization with the waveform display in the timeline and with other tracks. If an
effects chain includes non-in-place plug-ins, the effects chain icon will be displayed in yellow (
) to indicate that automatic plug-in
delay compensation is being used.
When input monitoring is on during audio recording, plug-in chains that cannot be used for live monitoring are automatically
bypassed and are displayed in red ( ).
