Adding audio clip without using video
Hello everyone,
I am currently putting together a video, but I don't actually have the video footage with me right now. I do have the audio footage though, which consist out of two separate audio tracks. I figured I'd use my current time to sync the audio files together, since they're not in sync yet. One track is computer audio, one is microphone audio.
I cannot figure out how to layer these two tracks in iMovie. When I import them and drag them down, they are put in the background layer automatically and I cannot drag them elsewhere or stack them at all.
I've read about adding audio tracks to your video clips, to make audio stack, but I have no video clips at this moment. Is this really the only way?
Thanks in advance.
iMovie 10, OS X El Capitan (10.11.3)
