Use ffmpeg to create an audio file from another audio file

Question

I’ve got an opus audio file that’s 10 seconds long. I need to create another, shorter opus file call File1.opus from the 10 second file. i.e.

Start offset: 3 seconds

Length: 2 seconds

Is it possible to create another opus audio file, from an existing opus audio file using ffMpeg?

If so, what command line would I use?

Many thanks
