Pricing Comparison
Studio Six Digital sells AudioTools as a suite of individual iOS apps, each priced between $19.99 and $29.99. To get the full measurement capability — SPL meter, RTA, RT60, signal generator, and more — you may spend $100-$150 across multiple app purchases. Each app is well-made and focused, but the modular pricing adds up. SonaVyx provides all measurement tools in a single free browser-based platform. The Pro tier at $29/month adds AI diagnostics, trending, and clean reports, but the core measurement suite is completely free.
Standards Compliance
AudioTools' SPL meter app is notable for meeting IEC 61672-1 Class 2 accuracy when paired with their iTestMic calibrated USB microphone. This hardware+software combination provides reliable calibrated SPL readings on iOS devices. SonaVyx implements IEC 61672-1 in software with user-importable calibration files (FRD, CAL), plus ISO 3382-1 for room acoustics, IEC 60268-16 for STI, and AES-2id for system alignment. SonaVyx covers more standards but relies on the user's microphone quality for absolute accuracy.
Platform Comparison
AudioTools runs exclusively on iOS, making it ideal for engineers who carry an iPhone or iPad to every job. The iTestMic accessory turns an iOS device into a calibrated measurement instrument, which is genuinely useful for on-the-go SPL measurement. The limitation is that you cannot use AudioTools on Windows, macOS, Android, or Linux. SonaVyx works on any device with a modern browser — including iPhones, iPads, Androids, laptops, and desktops. No app installation is required, and no proprietary hardware is needed.
When to Choose AudioTools
AudioTools is the right choice if you primarily need a calibrated SPL meter on iOS, already own or plan to buy the iTestMic, want quick single-purpose apps for spot checks in the field, and prefer the simplicity of dedicated iOS apps. The SPL meter with iTestMic calibration is genuinely one of the best mobile SPL solutions available.
When to Choose SonaVyx
SonaVyx is the right choice if you need transfer function measurement (AudioTools lacks this entirely), require STI/STIPA speech intelligibility testing, want AI-powered diagnostics and problem detection, need a full measurement suite without buying multiple apps, or work across different devices and operating systems. The browser-based approach means zero vendor lock-in and instant access from any device.
Summary
AudioTools excels as a set of focused, well-designed iOS measurement apps, with the SPL meter + iTestMic combination being particularly strong. SonaVyx offers a significantly broader measurement suite — including transfer function, STI, and AI diagnostics — accessible from any platform at no cost. If you are an iOS user who needs a quick calibrated SPL meter, AudioTools is excellent. If you need comprehensive system analysis, speech intelligibility, or platform flexibility, SonaVyx provides more capability in a single free tool.
