Our Approach

Diagram of our process. 01 Research: researchers work from papers on cutting-edge research. 02 Build: engineers, designers, and video creators build instruments as custom tools. 03 Create: musicians make works of music and video.

  • Starting from research

    We draw on peer-reviewed studies in sleep science, neuroscience, psychoacoustics, and psychology, and design our sound around those findings.

  • Designed for listening

    Techniques such as binaural beats are shaped into sound that stays comfortable to listen to for long sessions.

  • Listen in moderation

    Effects vary from person to person. Keep the volume low, and stop listening if it interferes with your sleep.
