Voluble by Vito

Voluble

Voluble is a handy extension for the Audible web player that allows you to adjust the volume of your audiobooks. To sum it up, Voluble adds an Audible Volume Control.
Voluble adds a simple volume slider that blends in with the design of the player and looks like it has always been there. With Voluble, you can find the optimal volume for your listening experience without changing the system settings of your computer or using another app. Voluble was developed out of necessity, since the Audible player itself does not offer a volume function and is therefore often too loud or too quiet.
Voluble is a good, simple alternative that gives you more control over your audiobooks. Voluble is completely free and open source. No data or tokens are ever forwarded to third parties or the author. You can view the code on Github and help improve the extension: https://github.com/Vito0912/Voluble

At the moment all languages, supported by Audible, are supported.

- other languages should still work, but they will only be translated into English (Some overflow might occur then)

If something does not work or your language is not supported, you can send me an email
