How to create music scroller with scroll effect?

The way I worded that is kind of weird, but let me explain. If you’ve used music apps such as Spotify, Soundcloud, or Windows Media Player, you can scroll through a song by grabbing the little circle thing and moving it on the timeline. That’s still kind of weird. Hmmm. I want to add a scroll thing that can scroll through different parts of the audio files I have. Is this possible to do? Is this too hard to make? Am I not clear lol?

If you know what I mean I would appreciate it if you helped me out.

Thank you very much.

PS: If you need me to be clearer, I’ll try.

AudioSource documentation. Should be pretty straightforward. You can read and write the current playback time, just bind it to a slider
