Description

LabStreamingLayer (LSL) already is a well-established tool for recording and accessing EEG and other signals in many labs around the world and interest in it is still growing. LSL makes it possible to combine several data streams into one single XDF file and access the streams with various clients online. These streams can be regular streams with a certain sampling rate, or irregular streams that send data only when needed. LSL is very well explained on its GitHub page and there is a comprehensive online documentation. In addition, we provide instructions here on how to use LSL with Brain Products amplifiers and tools in your experiments.
