SoundScope RTA

SoundScope for iOS single channel RTA is a full-featured audio spectrum analyzer. It provides advanced audio analysis using the latest FFT-based high-resolution algorithms and tools for detailed and precise audio analysis.
If you need a two-channel FFT for your iOS device, check out Transfer Function, a module in our AudioTools app.
SoundScope is based on our proprietary algorithms and techniques, and features.
Now, you can have the sophisticated analysis of SoundScope on the iPhone platform.
The single-channel module includes the following features: RTA Bar graph, RTA Line graph, RTA Bar & FFT graph, and the Spectrograph.
A variety of smoothing and averaging algorithms are available, including log, lin, Octave, 1/3rd, 1/6th, 1/12th, 1/24th and 1/48th Octave modes.
The decay modes include None, 1, 2, 4, 8, and 16 averages, and exponential 1-10 second custom decay settings, as well as Infinite, Fast, and Slow.
The frequency scale can be zoomed down to a single octave, and the dB scale can be zoomed down to 1dB resolution. Double-tap the screen to return to full frequency response, and to auto-scale the dB scale.
Real-time Spectrograph history is saved, just swipe to see sound events that have scrolled off the screen.
Other features include high-contrast mode, variable Spectrograph speed, vertical or horizontal running Spectrograph, Difference mode, Peak Tracking, and FFT Windowing.
New features include the ability to replace the background with a live video camera feed, and also do screen recording to capture a record the sound levels and also what is happening physically in the space. This is next-level VR audio analysis.
All of the standard AudioTools features, such as Save / Recall and the Generator Panel are available. All settings are automatically saved and restored the next time that you run the app.
On iPad and larger iPhones, split graph mode is available, so that you can put any two graphs on the screen at the same time. Check out the screenshots to see if your device supports them.
SoundScope RTA Spectrum works great with the built-in iOS device microphone, as we have proprietary microphone compensation and calibration database derived for every iOS device. To upgrade to full professional results, use our iTestMic, or iAudioInterface2 with any test & measurement microphone.
