App to fix the bad sound quality of your crappy laptop speakers

FxSound (formerly known as DFX) is a high-fidelity digital audio processing program. It brings you booming bass, crystal clear audio and high fidelity by optimizing your music in real time. That means you get a studio quality listening experience without the need for overly expensive headphones or speakers. FxSound simply runs in the background. Just turn on your music and enjoy an improved listening experience. Its features include:

• EQ: Balanced your sound with 9-band graphical EQ with customizable center frequencies.
• Visualizer: Built-in audio visualizer to feel your music.
• Effects: Boosted bass and volume to improve your music and movie viewing experience.
• You can also enhance clarity of audio or add ambiance and surround effects.
• Presets: Presets professionally designed for music, gaming, movies, transcription, and more. Additional presets can be found here. You can also make your own presets and share them.

FYI: Windows only

Yes, sadly, there are alternatives for Linux, like EasyEffects, but not so complete.

This is the only thing for me that makes the head sound audio work on windows 11

Also ... I miss Dolby Atmos support on Linux
