How do I amplify the volume of Windows?

Question

In my laptop, some YouTube videos have a too low volume to hear anything. I'm forced to download the video and play it in MPlayer where I can use -softvol to increate the volume.

Is there any software that can amplify Windows audio globally? Similar to how -softvol works on MPlayer but for all applications.

I'm using Windows 7, my sound card doesn't have any additional user interface apart from what Windows shows.

You can use Loudness Equalization as described in the link. It improves sound volume and is achieved like this :

• Control Panel -> Sound
• Right-click speakers and select Properties
• Select 3rd tab Enhancements and in that window select Loudness Equalization (More info in the link above).
