Measurement vs Simulation
The fundamental divide in room acoustics software is between measurement-based tools (SonaVyx, REW) and simulation tools (EASE, Odeon). Measurement tools capture what actually happens in a room using microphones and test signals. Simulation tools predict what will happen based on 3D models, material properties, and ray tracing or finite element methods. For existing rooms, measurement is always more accurate. For rooms under design or renovation, simulation is essential.
SonaVyx + AcousPlan
SonaVyx handles real-time measurement: RT60 per ISO 3382, room mode identification, impulse response capture, and treatment recommendations based on actual measured data. The AI treatment calculator uses a 55-material absorption database to recommend specific panel quantities and placement. AcousPlan, the sibling app, handles design-time room modeling and acoustic prediction. Together they cover the full lifecycle from design through commissioning. The browser-based platform means no installation and immediate access from any device on-site.
REW (Room EQ Wizard)
REW remains the most popular free desktop tool for room acoustics measurement. Its waterfall and spectrogram plots are excellent for identifying room modes and decay characteristics. The EQ optimizer generates correction filters for popular DSP platforms. REW lacks treatment recommendations, AI analysis, and cloud-based venue tracking that SonaVyx provides. It requires Java and a desktop operating system.
EASE and Odeon
EASE and Odeon are professional room simulation packages used by acoustic consultants and architects. They model sound propagation using ray tracing and image source methods to predict RT60, STI, coverage, and other metrics before a room is built. Starting at $5,000+, they target professional consultancy firms. Neither offers real-time measurement, making them complementary to measurement tools rather than competitors.
Choose the Right Approach
- Choose SonaVyx if you need real-time room measurement with AI-guided treatment recommendations in a browser.
- Choose REW if you prefer desktop software with advanced room correction EQ optimization.
- Choose EASE or Odeon if you design rooms professionally and need predictive acoustic simulation.
- Choose SonaVyx + AcousPlan if you want measurement and design-time prediction in one ecosystem.
