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.

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.

Nothing in the app listing said anything about EVERY feature being locked behind a subscription. Only after downloading the app, and expecting a limited feature set, I am greeted with a forced subscription page as soon as it opens. Sure, there’s a 7 day trial, but even the cheapest plan option is $60 to purchase outright. This is yet another, greedy, “own nothing and be happy” company that wants to push everyone to subscribe and makes a buyout option insanely overpriced.
