I recorded two audio tracks on a Zoom H4. The track recorded with a lavalier has uneven audio levels in FCPX. The left audio meter is much higher, the right is very low, almost non-existant. Why are they so uneven? Also with my headphones of course only one side is audible. Thank you for your help!
If the lavalier is the only source of audio you only need to use one channel ("track") since it is a mono source. With the clip selected, open the inspector and under the audio tab select the Channel Configuration and there change the audio to Dual Mono and disable the weaker track. Now the lav plays equally from both speakers.
