All of a sudden -- my voice on some of the clips and any voiceovers I do -- is very static sounding and distorted sounding. Everything always sounded great before. I record on my I Phone 7 but edit on my MacBook air. I record voiceovers directly into the mac with no external mic. I had the mac mic checked out today. It's fine. I've uninstalled and reinstalled RU -- the problem is still there. Help Please!
