Windows Audio Loudness Equalizer is a free tool that allows you to control the volume of individual applications on your desktop device. It is known as the Wale volume control tool and allows you to set volume levels and audio settings for apps that wouldn't normally have them.

It allows you to set some apps as silent by default in the same way that Letasoft Sound Booster does. It allows you to affect things like the bass, treble, softness of the sound some apps create, similar to how Equalizer APO works. You choose what this volume control tool makes loud and what it mutes.

Does this override game settings?

This tool applies sound control after the original program. For example, if you turn down the volume all the way on your game, you can't increase the volume using this tool. If you turn your game volume to full, however, it is possible to make it even louder with this app.

Is this a testing tool?

Though it wasn't built for testing, it does output enough information to make it useful to testers. Sound engineers and editors will understand the esoteric terms and data that it outputs, but most of the data it creates will baffle people.

Not a user friendly program

Despite the fact that this free volume control app does a good job at controlling system sounds, its user interface, instructions, and the overall aesthetic are not user-friendly. Almost no GUI aesthetic design has been applied, making this look more like an industrial utility program.

Lacking in features and tools

Considering the strength of competition that this equalizer app has to compete with, it is unfortunate they didn't offer more features and tools. Perhaps analysis panels, resource management, and peak volume-limiting that allows music to be played loud, but has system sounds like notifications come in much more quietly.
