Premiere Pro includes VST (Virtual Studio Technology) audio plug-ins designed to alter or enhance the properties of audio clips. Most of these effects are available for mono, stereo, and 5.1 clips, and can be applied to either clips or tracks, unless specified otherwise. If you have Adobe Soundbooth installed, Premiere Pro automatically locates, recognizes, and uses the VST effects from that program as well.
Each audio effect includes a bypass option that allows you to turn the effect on or off as specified by the keyframes that you set.
Audio effects are combined into a single, unified effect and displayed in a flat list inside the Audio Effects folder. When you apply an audio effect, Premiere Pro automatically applies the correct effect type (Mono, Stereo, or 5.1) to that clip. For a list and descriptions of the available audio effects, see Audio effects.
Certain effects have restrictions, and can be used only on certain track types. (For example, the Balance effect can be applied to stereo tracks only, not mono, or 5.1). The following effects have this restriction:
Balance (Stereo only)
Channel Volume (Stereo and 5.1 only)
Fill Left (Stereo only)
Fill Right (Stereo only)
Swap Channels (Stereo only)
Presets for unified audio effects can be created from single or multiple audio effects.
In the Audio Mixer, track effect options are controlled after an effect is selected in the Effects And Sends panel. If the Effects And Sends panel isn’t visible, display it by clicking the Show/Hide Effects And Sends triangle on the left side of the Audio Mixer. The Effects And Sends panel contains Effect Selection menus to apply up to five track effects. Premiere Pro processes effects in the order they are listed and feeds the result of an effect into the next effect in the list; therefore, changing the order can change the results. The effects list also provides full control over VST plug-ins you’ve added. Effects applied in the Audio Mixer can also be viewed and edited in a Timeline panel.
An effect can be applied pre-fader or post-fader. The difference is whether the effect is applied before or after the application of the track’s fader. Effects are pre-fader by default.
In the Audio Mixer, effect options that change over time can be recorded using the automation options or specified in a Timeline panel by using keyframes.
If you plan to use the same effect repeatedly, consider conserving system resources by sharing effects through a submix. Create a submix, apply the effect to the submix, and use sends to route tracks to the submix for effects processing.
You can move, copy, and re-order audio track effects in the Audio Track Mixer. This is particularly useful in scenarios where you want to rearrange effects in the track inserts area to change the gain staging and signal flow of the audio.
You can adjust the fixed audio Track or Panner effects either by manipulating the track keyframes rubber-band, or by using the controls in the Audio Mixer.
Click the menu at the top left corner of the clip in the audio track (it appears with Track:Volume as the default selection); then choose the effect name and property from the menu. Pre-fader effects appear at the top of the menu; post-fader effects appear at the bottom. Any numbers in the effect names refer to their position in the track effects list, their rendering order.
You can copy track effects from one section of a track and paste them into another. When pasted, the track effect keyframes land in the track from which they were copied, at the location of the current-time indicator. Targeting tracks does not affect where the pasted keyframes land.
Premiere Pro supports the Steinberg VST (Virtual Studio Technology) audio plug-in format so that you can add VST audio effects from third-party vendors. Premiere Pro includes VST plug-in effects that are available in both the Audio Mixer and the Effect Controls panel. Track-based VST plug-ins may provide additional controls. Apply VST effects the same way you apply other audio effects to tracks or clips.
In the Effects And Sends panels of the Audio Mixer, VST effects appear in the Effect Selection menus. In the Effects panel, they appear in the Audio Effects bin so you can apply them to individual clips. In most cases, VST effects appear in the Audio Effects bin and track type that corresponds to the number of channels the effect supports. For example, stereo VST effects appear in the Audio Mixer track effect menus for stereo tracks only, and in the Stereo bin in the Audio Effects bin in the Effects panel. After you apply any VST effect, you can open a window with all of its controls. You can leave multiple VST editor windows open as long as you want, such as when automating effects, but Premiere Pro closes all VST editor windows when you close the project.
If you previously installed a VST-compatible application other than Premiere Pro, Premiere Pro finds VST effects in the VST folder that already exists. Inside the Plug-ins folder of the Premiere Pro application folder, there is also a VST Plugins folder with plug-ins that are used only by Premiere Pro. The locations where Premiere Pro searches for VST plug-ins are as follows.
C:\Program Files\Steinberg\VSTPlugins (Windows)
System HD/Library/Audio/Plug-ins/VST (Mac OS)
System HD/<user>/Library/Audio/Plug-Ins/VST (Mac OS)
Regarding If you already have an audio application installed, there should be a VST plug-ins location in the registry stored here: HKEY_LOCAL_MACHINE\SOFTWARE\VST\VstPluginsPath Premiere Pro should use the path specified by that registry key. It should be set to something like this location: [Program Files]\Steinberg\VstPlugins\
When you use a VST effect not provided by Adobe, the specific control layout and results of the plug-in are the responsibility of the plug-in manufacturer. Adobe Premiere Pro only displays the controls and processes the results.
The Audio Mixer lets you open a VST editor panel, for certain VST effects, to adjust the effect options.
You can’t open a VST editor window from the Effect Controls panel.
