Hello everyone,

As the title suggests, are the raw file data saved in mVolts or uVolts?

I notice this got no reply. It might be that nobody knows. Ways to find out might include

  • asking an engineer at the company
  • looking up the normal range of dry EEG voltages, and seeing what is likely
  • seeing if there is a clue in the old sdk documentation: do any other programs report raw values with units?
  • using measurement equipment, a voltage generator, or another bci device, to test
  • decompiling the old research programs like museio
  • decompiling the muse mobile app
