Remember radio hosts? Some constant music would be playing behind them and as soon as they started speaking BGM would soften. I need something like that. I use a site https://asoftmurmur.com/ and I use it while I am studying. It's just to focus and drown out the noise. When I watch a video lecture its uncomfortably loud so I have to tweak it. Then I pause and have to think and note and I have to bump the volume up. This needs to happen like every five minutes average and doing it is a hassle. If only I could assign the volume of that tab as BGM. Whenever any other audio even my mic goes off, the volume of that tab should just adjust to not intrude and when there is no other audio it should bum back to its glory. Please recommend an extension or anything like that would solve my issue. Thank you!
