SIGVIEW is real-time and offline signal analysis software package with wide range of powerful signal analysis tools, statistics functions and a comprehensive visualization system. SIGVIEW is highly customizable and flexible but does not require any programming know-how.


Support for wide range of data acquisition devices, from common sound cards to professional DAQ devices. Various options for triggering, decimation and file-logging are included. The following device types are supported:

NIDAQmx compatible DAQ devices from National Instruments® (voltage input, IEPE velocity/force/acceleration)
Measurement Computing® DAQ devices (12/16/24-bit voltage input)
LabJack® U3 and U6 USB DAQ devices (voltage input)
Microsoft Windows® compatible sound cards (DirectSound and ASIO driver models are supported)
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 correlation,…)
Signal filtering (Bandstop, Bandpass, Lowpass, Highpass)
Real-time arithmetics 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 the calculated spectrum
Advanced signal display and handling options: unlimited overlays, unlimited number of markers and annotations for each signal, parallel signal display (EEG style), cut/copy/paste signal parts, unlimited zoom 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 for automation and remote control from external applications or from simple 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.

Field-proven by thousands of satisfied users.
