## Description

Audio Spectrum Analyzer dB RTA is a fast, precise real-time tool for frequency analysis and sound level measurement. It reveals the audio spectrum and shows the levels of various frequencies, while a built-in sound level meter provides ambient noise measurements in real-life scenarios.

Key capabilities include Octave Band Real-Time Analyzer, FFT Plot, Smooth HD Graphics, Multispectral Harmonic Analyzer, and an Integrated Sound Level Meter (dB-A weighted). It supports FFT sizes from 256 to 16384, Hold Max and Min peaks, linear and log scales, multiple window functions, fullscreen mode, and per-frequency tracking. Designed for both hobbyists and professional engineers tuning home theaters, cars, and other setups.

## Review summary

The app was once a capable real-time spectrum analyzer, with useful features and believable accuracy. However, it has become unreliable and largely nonfunctional due to crashes, lack of updates, compatibility problems with newer iOS versions, and unresponsive support. Many users report inaccurate measurements and broken visuals, leading to widespread dissatisfaction and refunds. The core strengths are now eclipsed by maintenance neglect and frustrated users seeking alternatives.

### Pros

- Historically useful for spectrum analysis and tuning when the app functioned.
- Provided real-time spectrum visualization (FFT) during working periods.
- The free version offered meaningful RTA capabilities and was appreciated before updates.

### Cons

- Frequent crashes and overall non-functionality after updates.
- Abandoned/unsupported by developers; not updated for years and incompatible with newer iOS versions/devices.
- Poor or no developer support (unresponsive inquiries) and lack of in-app help or documentation.
- Unreliable measurements (frequencies not identified correctly; FFT issues) and general accuracy problems.
- Trial limits hide most features, making evaluation difficult.
