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. In certain situations it can appear to increase volume by raising the volume of relatively quiet sounds. Enable it 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).

This procedure does not seem to make the loudest sound any louder.

I couldn't hear any difference. Also the link is broken. – Benjamin Mar 30 '13 at 10:06

You could also right click on the speaker icon and Volume Mixer to make sure that your browser's volume is not turned down. Sometimes Windows has a habit of adjusting the volume of things for you (each program that has sound has its own independent volume control).

Ha! I was looking for some obscure solution, deep in the Windows internals, when my solution was simply this. – Louis Mar 30 '14 at 10:02
