Lets face it, internal computer speakers are only so powerful.
Then there is a matter of sound quality.
Another alternative to Audio Booster Pro is Audio Booster Increase Your Sound.
This can also be found in the Google Chrome web store and functions similarly to Audio Booster Pro.
The biggest difference is the pop up window display.
Increase Your Sound will display the tabs playing audio, but only show audio levels on the extension icon.
The simplicity makes it more appealing for those who prefer less clutter.
Both have minimal differences in quality.
Increase Your Sound does seem to focus more on bass levels.
Audio Booster Pro provides a more equalized sound boost.
My suggestion is to download both extensions individually and test them out.
Audio Equalizer Extension
To improve audio quality, download theProfessional Equalizerextension.
Extensions can work wonders.
