Features & Capabilities

Smaart RTA brings desktop-grade real-time analysis to your browser with Real Time Analyzer, a spectrograph, and a crystal-clear SPL meter. It uses the same underlying algorithms trusted by live sound engineers for accurate, actionable data in real time. Note: Smaart RTA creates single-channel measurements only and does not support dual-channel transfer function measurements or impulse response measurements used for system alignment.

Pro features unlock advanced options: adjustable graph settings, calibrated level plotting, Target Curves (Cinema X or custom), capture/export of RTA traces (.srf), trace averaging, Y-offsets, and .srf import/export between desktop and mobile. It also includes an enhanced SPL toolset and an extended traffic-light display to help stay within venue limits.

User Reviews

Overall, users praise Smaart RTA as useful and easy to use with a desktop-like experience, but repeated concerns center on a subscription-driven model with high prices and no preview, plus a desire for real-time data integration with a connected computer.

Pros

Very useful tool and worth the money.
Desktop parity: close alignment with the desktop SMAART and compatibility with an RTA mic.
Easy to use and intuitive interface.

Cons

Subscription-only model with locked features, forced on launch and high prices.
No preview or trial before subscribing (difficulty exploring the app before paying).
Lack of real-time data sharing between the mobile app and a connected desktop SMAART.

Recent reviews

A very useful tool, well worth the money. The desktop version is great too!

Doesn’t seem to mention it in the App Store, but to use this app you MUST pay a subscription as in-app purchase. I’m not doing that, nor am I doing a free trial just to use this once. It looks nice from the demo, like audacity packaged up but as a paid version.
