Lab Streaming Layer (LSL)
Notes on the data
About LSL
LSL is a protocol that enables a streamlined and synchronized collection of time series measurements across multiple devices.
EmotivPRO’s LSL feature:
  • Supports research experiments that require sub-millisecond timing precision.
  • Allows efficient, two-way communication between EmotivPRO and other third-party software and devices.
  • Enables users to synchronize data streams across multiple devices.
  • Allows real-time processing of raw EEG data in third- party applications.
  • Allows you to send distinct markers (such as event markers) to different devices and synchronize those markers across devices.
To configure LSL in EmotivPRO:
  1. 1.
    Connect an EMOTIV headset to EmotivPRO.
  2. 2.
    Click on Settings at the top right-hand side of EmotivPRO.
  3. 3.
    Click on Labs Streaming Layer from the menu on the left-hand side of the screen.
  4. 4.
    You can then configure:
    • EMOTIV data streams that communicate with third-party devices or third-party software in LSL outlet mode, and
    • markers from third-party software to communicate with EmotivPRO.
