This site has support apps that can help automat simple tasks, like syncing audio. There is always a price, though. If you use a 3rd party app to sync your sound and merge it with your video take, you will lose the timecode in that sound file and it will be replaced with your videos timecode. This can be a serious issue if you need to go back to find a specific ISOs later. BUT, if that’s not an issue, these little apps can be huge time and effort savers.
