FxSound review
A free Windows system-wide enhancer with EQ, effects, routing, and spatial processing.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
FxSound is free, open-source audio enhancement software for Windows. It processes system audio through a virtual audio driver, making it suitable for music listeners, gamers, transcriptionists, and people using low-quality speakers or headphones. Core controls include an equalizer with adjustable frequency bands, audio effects, customizable presets, volume and bass enhancement, spatial audio processing, and playback-device selection. Installers are available for Intel/AMD and ARM64 Windows systems.
The main strength is breadth within system-wide audio processing. FxSound combines equalization, effects, preset saving, volume boosting, bass enhancement, spatial processing, and audio routing in one Windows application. Its virtual audio driver extends processing across system audio rather than limiting it to a single playback context. Command-line controls add options for managing presets, output devices, and equalizer bands. The equalizer also supports configurable band counts, giving users control over how broadly they shape sound.
FxSound is distributed without a paid plan, so there is no tiered pricing structure to compare. That keeps the product focused on its free feature set, while the open-source model supports access to the software without a subscription. The trade-off is platform scope: FxSound supports Windows, not multiple operating systems, and its category specifications do not include app profiles for separate application settings. Choose it if you want free, system-wide Windows enhancement with routing, EQ, effects, and spatial processing. Look elsewhere if you need support beyond Windows or distinct profiles for individual applications.
