Add an Audio Equalizer to Firefox, Chrome and other browsers
Audio Equalizer is a free cross-browser extension that adds an audio equalizer to the browser to get better control over the output of sound.
The extension is available for Firefox, Chrome, Opera and the classic Edge by default, but since it is hosted on the Chrome Web Store, also available for the new Microsoft Edge browser, Vivaldi, Brave, and many other Chromium-based web browsers.
Installation of the extension is straightforward. A test in a Google Chrome installation went through without any issues. The extension requires the “access all websites” permission since it runs on all sites and not on a selection of sites.
The extension icon is placed on the main toolbar of the browser, or, in the case of Chrome, in the new Extensions menu if it is displayed on the toolbar. You can pin it easily to the toolbar directly if that is the case to improve access.
A click on the extension icon displays the equalizer on the screen.
You can adjust the different frequency sliders directly in the interface, and the changes take effect immediately. Some users of the extension commented that the extension did not work all the time for them; some managed to fix this by reloading the page in question.
Changes are applied globally and not per-site or even page. This may be a problem, but you can resolve it by using the extension’s presets feature. Audio Equalizer ships with several presets, e.g. Rock, Full Bass, Live, or Headphones, and options to save and load custom presets.
You can save your own presets, e.g. for a particular site or type of audio, and use the load functionality whenever you are about to listen to audio that matches it.
Audio Equalizer comes with a handy on/off toggle to enable or disable its functionality, a reset button to reset all frequency changes to the default, and a mono option, useful for users with hearing problems.
Audio Equalizer worked fine during tests. The extension changed the audio output on the fly while videos were playing on various test sites. An option to make it save audio presets for specific sites and load these automatically would make it more comfortable.
