Recently I tested all audio addons, which were updated during the last 12 months. Volumemaxxing by Kernocal is the best for unstable live broadcasts. Its internal architecture seems to be innovative. But it fails the central promise to boost ANY playing audio. Instead, the list of websites where nothing happens is longer than for other addons: Bandcamp, Dailymotion, Spotify, Yandex-overlays… One positive exeption is Soundcloud. Long story short: At the moment, Volumemaxxing is only a secondary tool. I am hoping for further development. Maybe this rewiew will be updated soon.
