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

I understand the Apple policy’s… I read the other ratings. Why not make the app free, no subscriptions. I’d rather have to watch an ad to use some features. As was said in another comment…. I’m probably only going to use it once.
