Once an audio or video file is added, the app displays its information in a white preview box to the left. One limitation of the app is that it allows you to work with only a single item at a time. You can also simply drag and drop a file over the application window to load it.

To the left, you’ll find a Load Audio or Video File button for selecting the source file. The method it uses to gain or decrease volume is fairly simple and intuitive as well. As opposed to QMP3Gain, this application also lets you work with video files. As the name implies, the tool lets you amplify the sound of an audio track, but in addition, you can also reduce the volume level. However, if you needed a rather simple and easy to use alternative that doesn’t confuse you with its wide array of configuration options, Audio Amplifier Free is probably what you’re looking for. Previously, we covered QMP3Gain, a feature-rich open-source application that can losslessly adjust audio volume across many songs.

This forces you to constantly change the volume level in your media player, which is a major annoyance.
