SoundFixer by Val Packett

Helps you fix annoying sound problems on sites like YouTube: audio in one channel only, too quiet or too loud. (Unfortunately, this extension does not work on all websites because of cross-domain issues — but it does work on YouTube!)

About this extension
It’s annoying when audio on some videos is set to one channel only, too quiet, or maybe even too loud? SoundFixer helps you fix an array of common audio issues associated with streaming video.

No more "Plug your headphones only halfway into the jack" :D

(Unfortunately, doesn't work on all websites — specifically, we're not allowed to use the Web Audio API from a cross-domain <audio> source. Thankfully, YouTube is not cross-domain!)
