FFT Properties - Signal Analyzer

Time series and frequency spectrum analyzer optimized for handling of long signals (Big Data). Designed for scientists, engineers and hobbyists in need of detailed signal content information (vibration, audio, seismic, speech..) It features:

* Perform in-depth frequency analysis with an abundant selection of options. * Open arbitrary audio/video file with the Signal Analyzer. Take an in-depth look at the frequency content of the multi-channel DTS or AC3 audio tracks of movie files. * Direct support for text files, raw/pcm (arbitrary format) files and wav file format. * Ability to compare multiple averaged spectrums. * Excellent 3D Surface chart with unique navigation capability. * Multithreaded batch file processing for rate conversion, digital filtering, signal generation, signal modulation, demodulation, envelope detection and signal conversion. * Zoom-spectrum feature. Select higher resolution and narrower bands with any sampling frequency. * Arbitrary real number factor rate conversion with great speed and accuracy. * Real-time high speed narrow bandpass filter, can have any bandwidth limited only with the length of the signal. * Basic digital filter designer support with a wide range of optimal FIR and IIR filtering. * Math expression evaluator for scaling of signals. * HP Calculator style signal generator. * Save and load settings of all processing pipes and charts. * Frequency analyzer features non-parametric phase angle measurement of non-periodic signals and linear-phase peak filtering. * Analytical spectrogram with highest accuracy imaging in an FFT analyzer with time-frequency analysis. * Support for real time analysis of largest file sizes. * Read/write and analyze complex/analytical signals.
