SoundFixer is a browser extension that solves annoying sound problems on the web, specifically YouTube videos.

Sometimes, while you’re watching a YouTube video, you hear music in one channel, but not another. Or you may hear an audio clip with a lot of bass, but no vocals.

SoundFixer fixes this by offering you an option to control the audio level in each channel. You’re able to adjust the overall volume, volume for each channel, or apply an audio filter.

To fix sound, just click on the options button, click on “Enable/Disable for All Websites,” and make sure that “SoundFixer” is enabled.
