Re: Matching Audio Levels by Loren Risker on Oct 3, 2012 at 6:55:08 pm
2 quick options:
Put them in one compound clip and show the audio properties of the compound clip.
Under the Audio Enhancements section click the arrow next to Audio Analysis. Turn on Loudness and play with the sliders until they match.
Eye ball the waveforms and drag the audio level bar up until they all more or less match.

Thanks for that! I didnt explain that they are all on the same channel - part of the same recording, sometimes even the same person speaking but they get quieter / louder - is there anyway to average out the audio so it is a consistent volume?

You should set audio keyframes following Loren's suggestion. You can do this in the Inspector or in the clip itself. Zoom in and put your cursor over the clip. Move it slowly up & down and at some point you'll see "0 db" pop up. That's the starting point for every clip and it refers to the level or loudness of the clip. At the same time you see "0 db" you'll also see a faint horizontal line light up. That's your level line. When your cursor is over this line and you Option-Click you'll set a keyframe. Play until the audio is too low or too loud. Back up to just before the level change and set a keyframe. Then play until the audio gets too loud or soft. Set another keyframe and by dragging it up or down you increase or decrease the volume. So go through your clip and adjust your levels using keyframes so they are consistent. Watch your audio meters as you do this. Just be sure you NEVER go above 0 on the meters. Note that "0 db" shown in your clip usually won't produce 0 in the meters. It doesn't matter what db is in the clip just what's in the meter. Most recommendations are to adjust your levels so the meter reads around -12. Once you get keyframing your audio under control you should start investigating how compressors and limiters work. You'll find them in the Effects Browser under Audio > Levels. Also, there are many free tutorials. Just Google "audio keyframing fcpx" and a bunch will pop up.
