Any audio enthusiast will say without hesitation that YouTube is not the best option for listening to music, but that doesn't stop us from making certain adjustments to optimize its quality. One of the shortcuts at our disposal is to install an equalizer as an extension, and that's where Audio Equalizer comes in, which supports Firefox and the main members of the Chromium family. Moreover, the equalizer works with HTML5 elements, so it is not limited to YouTube.
If the audio on your computer is working well, then the logical thing is to maintain a hands-off policy and not interfere beyond volume levels, but if you think there is room to modify certain values, there are several paths you can follow. One of them applies changes to the whole system, taking advantage of the resources of the audio controller (if they are available). Then you can limit them to your favorite applications, as long as their developers allow it.
Another option is that the changes are only in the browser. We know well that YouTube music could use a pinch of equalization, and we can aim for that first, but it's not exclusive. In fact, if a site uses HTML5 audio and video elements, you can most likely modify them too. The first step is to install the Audio Equalizer extension.
How to equalize the audio on YouTube
Using the equalizer is limited to selecting a preset from the list (which are practically identical to those we remember from Winamp), or modifying one frequency at a time. We also have a preamplifier, a checkbox to force audio in mono, and a snap mode that makes frequencies 'elastic' when we adjust them. The ON/OFF button is very useful if you want to check how deep the changes are; Reset clears the configuration, and if for some reason the audio doesn't come out equalized, click the icon that reloads the tab at the top right.

Audio Equalizer has versions compatible with Mozilla Firefox, Google Chrome, and Chromium variants like Opera and Microsoft Edge. It has worked very well during our tests, and definitely deserves your attention.
