focus EEG Dev Kit Raw and Processed Data Pipelines

This article explains how data from your  focus EEG Dev Kit is streamed and processed.

The Dev Kit streams raw EEG data to the server for processing.

Processing on the server includes filters - pass band and stop band. FFT and down-sampling.

All graphs are generated by the server processing.

The raw data shown on the Device settings page is raw data from the device.

The raw data graphs are from the server processed raw - which converts binary into json.

Down-sampling is required because even the lowest sample rate is much higher than screen refresh times.

Saved files are always raw data with no filters or processing.
