Yeah, unfortunately while it’s very simple to set up compressor levels in a DAW or even in feature-rich players like VLC, I haven’t come across any easy way to blanket apply one to your computer’s output without weirdly looping it through something like Ableton.
It seems like it should be so simple to have in Windows sound settings, but it’s never been an option. Sometimes there’s a toggle for “normalization”, but that gives you no control at all. You at least should be able to set compression ratio, lower threshold (in dB), and upper threshold (in dB).
Try to find out as much as you can about what the job/career is actually like, ask people who are in that field, if you can try to get some experience as an intern.
The worst thing you can do is focus on a major without considering what the actual work will be like once you graduate. Even if you love studying a topic, the actual work may be much less fun in practice.
Try to get some part-time experience of your own as you can, even at sub-entry level/intern levels it should help you know better what kinds of jobs you would enjoy full time. It’s often hard to envision a job without having some exposure to the field.
