A free, open-source audio enhancer for Linux — with a 10-band equalizer, effects, presets, and real-time audio visualization.
FXSound is a popular Windows audio enhancer — but it has no Linux version. This project is a full Linux-native recreation with real PipeWire/PulseAudio audio processing, built with Tauri (Rust + React).
This isn't just a UI mockup — it actually processes your system audio through a 10-band EQ and effects in real time.
- 10-Band Parametric Equalizer — fine-tune from 32Hz to 16kHz, -12dB to +12dB per band
- 5 Audio Effects — Fidelity, Ambiance, Dynamic Boost, 3D Surround, HyperBass
- 10 Built-in Presets — Music, Movies, Gaming, Podcast, Bass Boost, Vocal Boost, Deep Bass, Treble Boost, Night Mode, Flat
- Real-time Audio Visualizer — FFT-based spectrum display with 32 frequency bins
- PipeWire/PulseAudio Integration — processes system audio in real time
- Power Toggle — instantly bypass all audio processing
- Authentic FXSound Dark UI — black and red theme matching the original Windows app
- Native Linux App — built with Tauri (Rust + React) for low resource usage

git push origin feature/your-feature-nameIs this the official FXSound for Linux? No. This is an independent open-source project inspired by FXSound (Windows only).
Does this actually process my system audio? Yes. The app uses PulseAudio to capture, process, and output system audio in real time with EQ and effects.
What Linux distros does this work on? Any distro with PulseAudio or PipeWire — Ubuntu, Arch, Fedora, Debian, Mint, Pop!_OS, Manjaro, and more.
Is it free? Yes, completely free and open-source (MIT license).
