I dont see the wave form and thus cannot expand it for some finer editing.
I thought we just drag the track down and the track expanded?
Post a sreenshot so we can see what is going on.
Maybe you need to render the audio.
Thanks Ann Bens,
I dont get that spread handle below the audio track.
Click on the right pointing triangles next to the track names to expand the tracks and get the waveforms.
too simple, but if you dont know greek (geek)...
