The volume of YouTube videos is too low to hear what the video creators speak clearly. Do you have the same trouble? If yes, it is worth reading the post where MiniTool offers two ways to help you increase the volume of online and local YouTube videos.

Have you tried dragging the volume slider to the maximum or turning the system sound to the highest level to increase the volume on YouTube videos? Generally, the two methods can work. However, the volume of some YouTube videos is still too low to hear clearly after some users use the two methods.

Is there no way to increase the volume of YouTube videos? Of course, not. You can try the following two ways about how to make YouTube louder. If you want to make the online YouTube video louder, you can try the first way. If you want to make the local YouTube video louder, please try the second way.

Way 1: Edit JavaScript in One Browser

The fist way about how to make YouTube louder is by editing JavaScript in one browser. How to do that? The whole process of editing JavaScript is quite easy:

Step 1: Open your browser. Here I take Google Chrome for example.

Step 2: Click the three vertical dots icon in the upper-right corner and then select More tools > Developer tools.

Step 3: You will see a page appear on the right side of the current page. Navigate to the Console tab.

Step 4: Paste the following codes after the symbol “>” under the Console tab and press the Enter key to run these codes.

var videoElement = document.querySelector(“video”)

var audioCtx = new AudioContext()

var source = audioCtx.createMediaElementSource(videoElement)

var gainNode = audioCtx.createGain()

gainNode.gain.value = 2 // double the volume

source.connect(gainNode)

gainNode.connect(audioCtx.destination)

YouTube videos should immediately become louder after you run these codes. If you want to make YouTube videos even louder, you should replace the number in the gainNode.gain.value = 2 // double the volume with higher values. You can also decrease the video volume by switching the number to 0.8 or 0.5.

Note: The volume will go back to normal if you refresh the web page or open another YouTube video. So, to increase volume of another YouTube video, you should run these codes again.
