About FxSound

FxSound is a Windows program that processes system audio to improve sound quality, volume and bass. It combines an equalizer, effects and presets, and targets the timbre, volume, spatial balance and dynamics of audio to compensate for lower-quality hardware. The site describes it as free software, while also referring to a paid version sold for unrestricted access, so current pricing is not clear. It is designed to run quietly in the background and to be simple enough for users without audio expertise.

Compatibility is limited to Windows PCs. The site states that Mac and Linux versions would depend on additional contributions, and that operating system restrictions prevent system-wide audio processing on Android and iOS.
