Same professional measurements. Browser-based. AI-enhanced. Fraction of the cost.
Choosing the right acoustic measurement software depends on your workflow, budget, and deployment environment. Smaart v9 by Rational Acoustics is the industry standard for live sound engineers, offering dual-channel transfer function measurement and real-time analysis — but at $1,299 per license with Windows/Mac only support. REW (Room EQ Wizard) is a powerful free tool popular in home theater and studio acoustics, but lacks real-time collaboration and requires desktop installation.
SonaVyx brings professional-grade measurement to the browser. Built on Rust WebAssembly for native-speed DSP processing, it implements the same algorithms (H1 transfer function estimator, Welch spectral averaging, IEC 61672 weighting filters) used by desktop tools. The key difference: zero installation, mobile support, and AI-powered diagnostics that provide actionable recommendations — not just data.
For live sound engineers who need quick measurements at load-in, SonaVyx eliminates the laptop setup time. For acoustic consultants running ISO 3382 RT60 measurements, the guided workflows ensure standard-compliant results. For venue operators monitoring SPL compliance, real-time metering with OSHA threshold alerts runs on any device with a browser.
All measurement tools are free with no account required. Pro features ($29/month) add Claude AI diagnostics, watermark-free reports, cloud venue history, and priority support. Whether you are switching from Smaart, supplementing REW, or starting fresh, SonaVyx provides the measurement capabilities you need — instantly.
“Reduced venue measurement time from 3 hours to 45 minutes. The AI diagnostic caught a phase issue I would have missed.”
