Turn volume up over 100% in Windows 7

I find that for some applications, even turning the volume up to 100% on their application or the master volume just isn't enough. Is there some setting somewhere where I can push the limit?

I suppose you're talking about a laptop with built-in speakers.

I'm afraid there isn't much you can do, unless the driver/software for your sound chip provides such a feature (e.g. Realtek's Control Panel/Equalizer).

Some media players can boost the volume (e.g. VLC up to 400%) but that wouldn't help you to increase the volume for a certain application.

Other than that, get a set of speakers with decent amplification, also the sound quality will improve.

Check the Control Panel of the Audio Software to see if you have some loudness protection checked.

Control Panel > Sound > Speakers, Properties > Enhancements = (in the scroll down menu) Loudness Equalization, deselect if needed.

Try DFX audio enhancer - it did the trick
