I was looking at tutorials for CS6 and when I look at After Effects CC, the waveforms are cut in half making it harder to find beats of a song. If anybody knows a fix, please tell me!
That's a different way, and in my opinion, once you get used to looking at it, a Rectified waveform is a better way to use a waveform as an editing guide.
In the timeline window, right next the the comp name you'll see three little lines. Click there and deselect Rectified Waveforms.
