These days many videos are published to the internet by people using cellphones. Many of these videos have crappy sound, because of how these cameras are built and the way these cameras are used.

The microphones are not at the best place for recording the sound and because the volume is too low, there is much background noise, because the volume needs to be increased.

With the Flash player based videos we are dependent on Adobe (for Flash), the video owner or the video website too give us content or technology that lets us improve the video.

In the future with the new video tag it could (or maybe should) be possible to have extensions that will filter the audio of video streams on a page.

Would it be possible to create extensions in Firefox that will filter the audio of video’s to make the sound better?
