![]() The signal can then be explored in the time domain. You can add time information and sample rate for the signal or bring in signals as timetable which has inherent time information. You can drag the signal you are interested in, into the display to visualize it. The app accepts MATLAB variables including timetables and complex signals. All supported signals in the MATLAB workspace are available in the workspace browser here. The Signal Analyzer app can be launched from the MATLAB command line, or from the apps gallery. The app provides a way to work with many signals at the same time and in the same view. You can also easily apply various preprocessing techniques to the signals in the app. You can explore signals and identify and extract key features. How to Use:-Touch and move in the result area with one finger to use the measure line.-Touch and move in the result area with two fingers to rotate the 3D graph.-Touch and move in the summary waveform area to move the current position.-Tap in the scroll bar area(bottom of screen) to re-seek the current position.The Signal Analyzer App in the Signal Processing toolbox lets you visualize, analyze, and compare signals in the time, frequency and time-frequency domains without needing to write any code. Press "File" button to see the HTTP address, it is in the bottom of the window.-For more information, Please visit. You can also change the position while playing.Note:-The internal mic of iPhone first generation can only works on 8K sample rate, you need head-set to achieve 44k. (iPhone 4, iPod touch 4 and iPad required)-Current waveform display and summary waveform display.-Record at any position and red color to mark the latest recording, unlimited recording time.-Play back the recording.-Oscope Auto-Scale: Enable you to view more details for low level signal.-Snap to Peak: Find peak more easily while using measure line.-File Manager: Recording in wave format, create new files, delete exist files, etc.-Wifi Transfer and Data exporting: Download wav files with your browser, including screen shot, FFT result in txt file.-Touch in the result area to use the measure line, bordered label means where is a peak.-Move in the waveform area or touch on the bottom of the area to change the current position, iAnalyzer re-compute and update graph automatically. Sync display on your device and extern screen. (Require iPhone 4S and later, iPad 2 and later which shipped with multiple cores processor.)-VGA output support. With this feature, you can listen to your recoding very slowly. Powerful synthesizer to allow you replay the audio with different speed, from 1/8 to 4x. This is definitely a Must Have app for every musician or sound engineer.We also released the Mac version, you can download it from "Mac App Store".Features:-High performance software design for Real Time Analyzing(RTA) and complex graph displaying.-Works on 44K sample rate, 20~20k Hz frequency output.-FFT spectrum, Octave and 1/3 Octave result display.-Colored curve depend on the dB value.-Flex FFT size, 4K, 8K, or 16K.-Reference Pressure configurable.-2D or 3D or Mix 2D&3D display.-History result display while in 3D mode.-High precision peak frequency computation(average-error < 0.1%).-Auto peak frequency tracing, up to 3 peaks can be displayed simultaneously and each one be linked from text to the graph clearly.-Frequency to music scale converter, you can use iAnalyzer as a professional instrument tuner, or to test if any sound is tuneful. After 4 years of good sales all over the world, we are glad to see that iAnalyzer has gradually become the industry standard in audio analyze field, due to it's very high quality of course. IAnalyzer is a FFT based professional software to analyze the audio signals for iPhone, iPod Touch and iPad. ![]()
