SigViewer is a viewing and scoring software for biomedical signal data.

SigViewer is a powerful viewing application for biosignals, originally designed to display electroencephalographic (EEG) data. 

SigViewer now supports several biosignal data formats through libbiosig4c++ (for example GDF, EDF, CNT, EEG, and many more). 

Besides displaying biosignals, SigViewer supports creating annotations to select artifacts or specific events. 

SigViewer also features signal processing modules, for example it is possible to calculate the average and the power spectrum of selected signals.

SigViewer is written in standard C++ using the platform-independent graphical user interface (GUI) toolkit Qt 4. SigViewer is available for all three major platforms (namely Windows, Mac OS X, and Linux) using only one common source tree. Moreover, it does not depend on any proprietary tools such as Matlab or the Microsoft Foundation Classes (MFC), making it a truly free open-source program licensed under the GPL.
