Using Audio in Trapcode Form

For those who want to manipulate the audio within a video clip, Adobe After Effects’ Trapcode Form can be quite handy. Users can do this either via audio presets or by manually changing the Audio Layers reactors. People at any skill level will be able to learn and use this tool.

Step 1: Picking an Audio Track

The first thing that the user needs to do is open up the Effects Controls, and then drag their audio to the timeline. Since he probably will not need the camera option right now, he can just click on the button to turn it off.

Next, play the audio until it gets to the correct section. Keyboard shortcuts for this command are either the comma or the period depending on the version that is being used.

Step 2: Using the Trapcode Form

Once the audio is the correct place, users can add additional audio effects by using one of the Trapcode Form’s presets. These presets will add a variety of extra sounds to a person’s audio track, including additional base or higher frequencies. The purpose of these audio sounds is to add more depth to a track and to make it match the clip with which it is matched.

To start using the presets, simply go into the Animation Preset. Within this dropdown menu, users will see a number of different audio effects. They may want to experiment with these presets until they find one that best matches the audio. Then, select it.

Step 3: Selecting the Audio Layer

Next, the Audio Layer needs to be selected. The Audio Layer option is located within the Audio React. The layer must always be selected, or the effect will not be applied. Further, any time that a person wants to manipulate or change the audio presets, they will have to reselect the layer. It does not stay selected once an audio effect has been rendered.

Once the layer is selected, the audio can then be rendered.

Step 4: Adding Personalized Audio

While the presets are the easiest way to use this tool, users can also manipulate their own audio. To do this, go into the Audio React, and select the Audio Layer that needs to be changed.

For these effects, turn the Camera back. This will allow the user to see how well their changes match the video clip. Within the Audio React dropdown menu, there will be five Reactor options. Each Reactor can be set to a different frequency, which will create a mix of sounds.

Within each Reactor setting, users can change the settings for Time Offset, Frequency, Width, Threshold and Strength. And, these settings can be mapped to different features, including Particle Size, by changing the Map To settings. The Map To option is great for users who wish to match the movement of the items within a clip.

Once all the features have been changed, users can preview the settings to see how well it looks, and then render the entire clip.
