SVAROG

Signal Viewer, Analyzer and Recorder On GPL

SVAROG is the best bioelectrical signal viewer in theÂ FOSSÂ world, developed by BrainTech since 2012 on the basis of the university project titled SignalMLÂ â€“Â a metalanguage for dataÂ andÂ tagÂ description.

As one of the EEG solutions offered by BrainTech, SVAROG makes it possible to record and view signals online using video EEG and tags. At this website, you can find an offline version of our software which allows for the following, among other things:

Averaging evoked potentials using tags
Creating filters and applying them to signals viewed
Displaying spectra for individual signal fragments
Tagging structures offline
