I have a couple of large audio files and I want to split them into 30 minute tracks (the length of my gym sessions). I can’t see how to do it. Can anyone help?
There are a couple of ways to do that.
You can select/highlight the part you want to “save” and then, File → Export → Export Selected Audio to create a new file.
Typically, I’d cut it a little long and then re-open the new file and trim.
To avoid a “click” at the beginning or end, cut on the [u]Zero Crossings[/u] or make a fade-in/fade-out. If you don’t want to hear the fade-in/fade-out you can make very-short fades (a few milliseconds). You can zoom-in for more precise fading/trimming.
