Hi Jan!
Welcome to the Forum!
I've requested the "direct support for audio tracks" feature for years. 
You can create a .mp4 audio file which allows display in the Timeline. But there is no native support for waveforms, no timing markers or labels for the Timeline track; all of which makes syncing with animations time consuming.
Not having (at least some of) these types of audio features in an animation program that's been around this long is disappointing.
