Sigview 2.5

SIGVIEW is a real-time and offline signal analysis software package with wide range of powerful signal analysis tools, statistics functions and a comprehensive visualization system.
With its unique user interface and philosophy, SIGVIEW gives you the absolute freedom to combine different signal analysis methods in any possible way - there are almost no artificial rules and limitations. Once you get the basics, everything else in SIGVIEW follows the same logical pattern.

Main Features:

- Support for wide range of data acquisition devices, from professional DAQ cards to common sound cards. Various options for triggering, decimation and file-logging are included.
Real time data display, signal analysis and control. You can work with live signals and observe results immediately.

- Import and export of signal files in numerous formats: WAV, MP3, ASCII, WMA, AU, AIFF, SND, 8/16/32-bit binary files, EDF...

- Optimized FFT algorithm with fine parameter tuning and various pre- and postprocessing options: windowing, zero-padding, power spectrum and PSD, automatic averaging, test for spectral peaks integrity,...

- Spectrogram and Time-FFT functions with powerful graphical display solutions

- Dual channel (cross-spectral) analysis (cross spectrum, coherence, cross corelation,...)

- Signal filtering (Bandstop, Bandpass, Lowpass, Highpass)

- Real time arithmetic operations on signals (subtract, multiply, add, scale, normalize...)

- Various statistics functions: peak hold, averaging, smoothing, removing linear trend, probability distribution... Analog-style instruments for real-time display of important signal parameters

- Custom filter curves can be freely defined and applied directly to time-domain signal or to calculated spectrum

- Advanced signal display and handling options: unlimited overlays, unlimited number of markers and annotations for each signal, parallel display (EEG style), cut/copy/paste signal parts, unlimited zoom-in levels, VCR-style commands for audio playing,...

- Signal generator including sine signal, white and pink noise, step signal, sweep signal,...

- Graphical block diagram environment improves productivity when working with complex analysis systems

- Custom tools and workspaces can be created and later reused or exchanged with other Sigview users

- Various command-line options available for automation and remote control from external applications or batch files

- No artificial or license-based limitations: million points FFTs can easily be calculated; dozens of signals can be combined and analyzed at the same time.
