Scrubbing Audio and Audio Previews in Adobe After Fx
With most of the projects that come across my desk they always seems to come a section where I need to find a specific point in the audio. There are a number of ways to preview your audio in Adobe After Effects. One of the easiest ways is to just click your audio file in the right in the project window.

If you press the Period key on the number pad of your keyboard it will give you will receive a ten second audio preview. You can also press your Caps Lock key prevent anything to show in your Comp Window. Then press Shift + Zero (on the key pad) to create a ram preview. When the Caps Lock is on, your comp window will highlight red to remind you not freak out when you don't see video.

Every now and again you'll have to get to the nitty gritty of your video and listen for distinct sound within frames. That is where audio scrubbing comes in handy. Hold down the Control/Option key then drag your time marker and your will hear a preview of your audio as it moves through the timeline.
