If you need to improve your listening experience on audio hardware, you must have a good sound equalizer installed on your PC. They play the vital role of adjusting the speaker parameters to suit the mood and music playing.

On Windows 11, some individual apps like the Media Player give sound equalizing functionality, but, the ultimate sound or music experience comes with some third-party audio equalizers.

What is an audio equalizer?

A PC audio equalizer is software that allows you to tinker with the loudness and density of bands or specific audio frequencies. These adjustments improve the sound quality and make it more suitable for the listener.

An audio equalizer will allow you to boost the bass or trim the treble effect to make it more appropriate for a room that reacts to sounds with low frequency.

Audio equalizers on your Windows 11 OS will digitally reproduce the same effects of turning and adjusting nobs in the traditional hardware equalizers.

The legacy app and the new FXSound app have free versions. FX Sound provides an easy learning curve if you have ever used traditional audio equalizers. In addition, it provides a simple tunable for adjusting sounds.

Its downside will be the compatibility issues with extreme audiophiles, attributed to a capacity of 10 bands ranging between 110Hz and 15KHz. The preloaded presets compensate for the small band capacity.

Sliders are conspicuously missing on the new FxSound app, and you will only have to hit the ON button for the app to produce real-time enhancement of sound.

On this app, you will have the options for several presets, including music, games, video streaming, etc. It is an easy-to-use option if you have no prior sound processing knowledge. Users of FX Sound will be able to include a variety of effects, including surround sound, ambiance, and clarity.
