Time series and frequency spectrum analyzer optimized for handling of very long signals. It features: * Recording and playback with arbitrary real number sampling frequency with a real time sample rate converter of user configurable quality. * Real-time envelope and energy computation during recording with history overview and frequency analysis. * Real-time high-resolution spectrogram in the recording and analysis modules. * 24-bit/96kHz and 24-bit/192kHz recording and playback support. * Monitor and record output of arbitrary playback device. * Open arbitrary compressed and non-compressed audio/video files. Support for multi-language multi-channel DTS and AC3 movie files. * Support for text files, raw/pcm (arbitrary format) files and wav file format. * Frequency analysis and ability to compare multiple averaged spectrums. * Excellent quality 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. * 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. * Phase angle measurement of non-periodic signals and linear phase peak filtering. * Support for real time analysis of largest file sizes.
