SVAROG

Signal Viewer, Analyzer and Recorder On GPL

SVAROG is the best bioelectrical signal viewer in the FOSS world, developed by BrainTech since 2012 on the basis of the university project titled SignalML – a metalanguage for data and tag 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
