Play your video in your Final Cut Pro sequence and listen closely for key sounds. If your video is of people talking, pick out a specific word. If there are long periods of silence, take note of what sounds end that silence -- such as a car driving by or a bird chirping. Choose a sound that will be easy to identify to help you in the next step. Pause the cursor on the sound you've chosen. Right-click your mouse, and click "insert marker." - 4). Double-click on the good audio file in your bin in Final Cut Pro so that you can listen to it without it being in your sequence. Listen to the file for the same sound you pinpointed and marked earlier. Once you find it, pause the audio clip. Press the "i" key on your keyboard to set an in point.
- 5). Drag your good audio file into your sequence in Final Cut Pro. Since the in point of your good audio is approximately the same as the point in your bad audio file signified by a marker, line up the beginning of your good audio file with the marker.
- 6). Extend the good audio file to the left so that it stretches to the beginning of the sequence.
- 7). Zoom in close enough to the clips in your sequence so that you can see specific waveforms. If you can't see the waveforms at all, right-click the icon in the bottom left corner of your sequence that allows you to make your layers thicker. Click on the right-click drop-down box to access the option of making audio waveforms visible. Make your layers thicker so you can see the audio waveforms more easily.

Find the highest waveform in your bad audio clip. - 9). Click and drag your good audio clip until the highest waveform matches up with the highest waveform on your bad audio clip. Play your video. If the two audio clips don't match, continue to drag your good audio clip a frame or two to the left and right until you can hear no difference between the clips.
