Очень полезное дополнение. Для тихих роликов - самое то.

Wonderful audio boost for web audio, very very thankful to developer for very useful app. 5 Star.
I request to developer; please increase the volume gain a little more in the extension script.Thus we can more boost, this is not harmful to speaker because the main volume control is in our hand so we can adjust at desired level. Regards

I was looking to increase the volume of a video I was watching. With SoundFixer, I didn't need to plug in my speakers!
Great job guys and thank you!
