Play multiple streams with automatic leveling within browser?

March 12, 2020 9:58 AM

When I need to absolutely get shit done at work, I've found that playing classical opera in one tab, and a numbers station in another tab simultaneously, is great to drown out distractions. (since I don't know Italian, and many of the numbers stations are in Russian, my incoming language buffer is full, but has nothing to actually latch on to.) My biggest problem is that most of the time a playlist jumps to the next item, I have to go and adjust the volume.

What I'd really like is a tool or browser item that can cue up two tabs, and automatically level the volume as "Maria Callas - Greatest Hits" and "Lincolnshire Poacher Volume 1" playlists play through. Browser: Firefox on a work computer (so no add-ons).

I was about to suggest Equalizer APO, which has a "Loudness correction" filter, but it installs as a sound device so admin access is required.

My Noise is a website and app that you can use to create custom ambient noise. Here's their Numbers Station. While I couldn't find any opera, there are some other options. Chapel Voices / Tibetan Meditation / Aeternitas

You can build your own combinations, and they'll run forever.

Best answer: If you're running Windows, it has a built-in loudness equalizer that you should be able to enable. It's not perfect, but depending on the sound sources, it should at least improve things.

(Note that the instructions I linked to are slightly out of date. On Windows 10 build 1903, you'll need to click the "Sound Control Panel" link under Related Settings from the Sound Settings UI. Click Start > Settings (cog-wheel menu ⚙), then choose System > Sound, then find the Sound Control Panel link there.)
