Cutting Audio Length?

I have created a video, but my audio track lasts too long, it makes a black blank screen with sound.
I would like to cut out part of the audio, but can’t seem to figure out how.

Thanks for the help in advance.

Disable (mute) audio on your video track.
Create a new audio track (Ctrl+U) and copy the video to it. Then you can edit the audio track’s length.

For any future people looking to do the same as Ellisand above and don’t understand Steve_Ledger’s explanation like me, I found the following short tutorial on youtube: https://www.youtube.com/watch?v=tG0oiZj_07o This tutorial made it much easier to understand as you get to see it as he explains it. Hope this helps.
