Where REW Wins: Room Correction
REW was built for room correction. Its parametric EQ optimizer generates filters that can be exported directly to miniDSP, Dirac Live, and other DSP platforms. The multi-subwoofer optimization tool calculates delay, level, and polarity for integrating multiple subs with main speakers — a critical capability for home theaters with 2+ subwoofers. The 3D waterfall plot visualizes modal ringing and decay in a way that the SonaVyx spectrograph cannot fully replicate. For home theater enthusiasts who invest in hardware DSP correction, REW remains the superior tool for generating those correction filters.
Where SonaVyx Wins: Speed and Guidance
SonaVyx requires zero installation. Open a browser, allow microphone access, and you are measuring within seconds. For a first-time home theater owner who wants to understand their room before investing in DSP hardware, SonaVyx provides immediate value. The AI diagnostic engine explains what the measurements mean in plain language. RT60 measurement with room type targets tells you whether your space is too reverberant for cinema. The treatment calculator recommends specific acoustic panels with quantities and placement. This guided experience is far more accessible than REW raw measurement data for newcomers.
Subwoofer Integration
Subwoofer integration is the most common home theater measurement task. SonaVyx transfer function with phase display shows sub-to-main alignment and identifies cancellation frequencies. However, REW multi-subwoofer optimizer automatically calculates optimal delay, gain, and polarity for each sub — a significant advantage for dual or quad sub setups. If you have one subwoofer, SonaVyx transfer function is sufficient. For multiple subs, REW multi-sub optimizer saves hours of manual tuning.
The Best Approach: Use Both
SonaVyx and REW are complementary for home theater. Start with SonaVyx for a quick room assessment: measure RT60, check for room modes, get AI treatment recommendations, and identify the biggest problems. Then use REW for detailed room correction EQ generation once you have DSP hardware installed. SonaVyx AI diagnostics guide you on what to fix first, and REW optimizes the correction filters. Both are free.
Choose the Right Tool
- Choose SonaVyx if you want quick room assessment, AI-guided treatment advice, and zero-install convenience.
- Choose REW if you need parametric EQ optimization and multi-subwoofer integration with miniDSP or Dirac.
- Choose both for the most complete home theater measurement workflow at zero cost.
