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. Connect an EMOTIV headset to EmotivPRO.

  2. Click on Settings at the top right-hand side of EmotivPRO.

  3. Click on Labs Streaming Layer from the menu on the left-hand side of the screen.

  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.
