SigViewer is a free, open-source, cross-platform desktop application for exploring biosignal recordings, particularly EEG and MEG. It is designed to stay fast and responsive even with large files, making it easy to inspect multichannel time series and create, edit, or review events such as annotations and artifact selections.
- Browse multichannel recordings with independent time and amplitude zoom controls.
- Review, create, edit, and organize events alongside the signal display.
- Open common biosignal formats through libbiosig, including GDF, EDF, BDF, BrainVision, CNT, and BKR files.
- Open XDF recordings through libxdf, including compressed
.xdf.gzand.xdfzfiles. - Export event lists to CSV or EVT, and save events in GDF files.
