How do I get the length of a audio file?

Hi!

I am working with a lot of sounds in Construct 2 at the moment and one thing i just can't figure out is:

How do i get the length of a sound file? Aka duration.

I've figured out that Audio.Duration is something but i tried some combo's that didn't work ( like Audio.Duration("Sound1"), Sound1.ogg etc.

So my question is fairly easy. Is there a way to get the duration of a sound?

Why? I want to use the duration of a sound to change a objects width.

Any help is appreciated! Thanks in advance!

It needs to be playing for the duration expression to work.

Ashley Thanks for your reply.

Will find another solution for my issue. Thanks for the quick answer!
