Sound Control is a unique application that adds advanced audio controls to your Mac. Control the audio of each of your apps independently with per-app volume, EQ, balance, and audio routing.
I know this feature is free for Windows users and there are many free sound control apps for macOS too, but paid apps usually have better support and updates. There is a 14-day trial to find out if it suits your needs.

$20 for such a basic app is still too much
