Step-by-Step Guide to Working with Audio in After Effects
Start the process by importing your audio file into After Effects. First, it is important to listen to the sound properly. To activate the audio preview, simply press the comma key on your NumPad. This allows you to hear the sound from the current position. This is useful to immediately determine where exactly you want to begin with your animation or effects.

Once you have a feel for the rhythm and structure of the sound, you can start setting markers. Setting markers is one of the best methods for managing audio in the timeline. You can set markers either on the composition layer or specific markers on a particular layer, such as a null object or the sound file.
To add a marker, use the star key on the NumPad. If that is not available, Mac users have the option to set a marker using the Control + 8 keyboard shortcut. This method also works while playing an audio preview or RAM preview, allowing you to make precise adjustments at any time if the timing is not quite right.

Another useful tip when working with markers is that you can quickly navigate between marker positions by holding down the shift key. When you click on a marker, you can easily jump to it and edit it. You can also delete markers or protect them to avoid accidental shifts.
If you can’t quite remember what’s behind a specific marker, there is a handy solution. Hold down the control key and scrub through your audio. This will give you the opportunity to listen to specific sections of the sound directly. If you stop at a point, a preview of the next part will be shown, making fine-tuning and selecting suitable moments easier.
After you have set the markers and identified the best spots in the music, you can add graphic elements to your composition. For example, select a shape layer and place it where desired. By holding the Alt key, you can set the in-point, with the shape appearing in sync with the desired point in the music.

Utilize these techniques in your projects to enhance the precision of your animations. Often, it helps to work simultaneously on animating and cutting to seamlessly connect the effects and sound. The markers and scrubbing function provide you with an unprecedented level of control, allowing you to fully focus on the creative work.
