FxSound vs Boom 3D: Which Audio Enhancer Is Better?
FxSound and Boom 3D are two of the most commonly recommended audio enhancement tools, but they're built for slightly different audiences. This comparison looks at how they differ in practice so you can decide which fits your setup.
Platform support
This is often the deciding factor before features even come into play. FxSound is Windows-only, while Boom 3D supports both Windows and macOS. If you split time between a Mac and a PC and want one consistent tool, Boom 3D has the advantage here. If you're Windows-only, this difference doesn't matter.
Pricing model
FxSound's core audio enhancement — equalizer, bass boost, 3D surround, and presets — is free for personal use, with an optional premium tier for additional customization. Boom 3D typically operates on a paid license with a free trial period, after which continued use requires purchase. For users who want a permanently free option, FxSound's free tier is the more accessible starting point.
Ease of use
Both applications are designed for non-technical users, with preset-based workflows that don't require manual EQ knowledge. FxSound's interface leans slightly more minimal, focusing on a small set of controls, while Boom 3D includes additional visualizer and equalizer customization screens that may appeal to users who like more visual feedback.
Audio processing features
Both tools offer system-wide processing, 3D surround/spatial widening, and genre-based presets. FxSound's distinguishing feature is its harmonic restoration technology, aimed specifically at rebuilding detail lost to audio compression. Boom 3D emphasizes its 3D surround technology and equalizer presets tailored to specific headphone models.
Open-source transparency
FxSound's core engine is open-source, which appeals to users who prefer to know how their audio is being processed or who want to inspect the code. Boom 3D is closed-source commercial software, which is standard for paid utilities but offers less transparency.
Which should you choose?
If you're on Windows and want a free, lightweight option with no recurring cost, FxSound is the more practical starting point — you can always try the premium tier later if you want more presets. If you need cross-platform support between macOS and Windows, or prefer a paid tool with dedicated support, Boom 3D's trial is worth evaluating. Many users try FxSound first simply because there's no cost barrier to testing it.
