Browser extension to boost the volume of a video on a web pages

Up To Eleven

A Web Extension that inserts a Web Audio API GainNode and DynamicsCompressor node to increase the audio level of videos that are too quiet, while limiting the maximum volume of those videos.

A few examples:

• https://www.youtube.com/watch?v=23lRkdDXqY0
• https://www.youtube.com/watch?v=FJoYZUMOwM4

This is a proof of concept: the input gain to the compressor is fixed, and the compressor parameters are fixed as well. A byproduct of this technique is that the background noise is going to be increased.
