Brain.fm

Brain.fm is a functional music service that plays audio engineered to influence brainwave activity and help listeners concentrate, relax, meditate, or fall asleep. Ordinary music or generic focus playlists can themselves become a distraction, with lyrics, abrupt track changes, and inconsistent energy levels. Brain.fm addresses this by composing instrumental music with patented audio technology, developed with neuroscientists, that aims to support specific mental states rather than simply entertain.

The service works by identifying the brainwave frequency range associated with a target mental state—such as beta waves for focus or delta waves for deep sleep—and embedding corresponding volume modulations into the music. The company states that this approach enhances and synchronizes brainwave activity across the brain, and that its research has been published in a peer-reviewed journal (Nature Communications) and supported by a grant from the U.S. National Science Foundation. Listeners choose a mode, such as deep work or wind down, and the app streams matching audio without manual searching.
