Beneath a glowing pyramid, a seasoned meditator sits peacefully in lotus position, wearing an EEG (brain wave) headband. As their meditation deepens, the pyramid pulses and responds.
An EEG headband captures live brain waves from a person meditating beneath the pyramid. The pyramid responds with EEG-driven projection, lights and sound.
Meditators are the crown jewel of Mind Murmur. As their meditation deepens into Alpha and Theta brain wave states, video and sound become increasingly lush.
Live EEG data drives mammoth fractal art that blooms across the pyramid's walls. Color, speed, and shape shift with the meditator's brain states. watch
Sensual sound flows through the pyramid, cued by the meditator's brain waves. Animal calls, heartbeats, murmured prayer, synths, chimes and bells... sonified, sculpted, musically intertwined. listen
Mind Murmur uses an elegant custom algorithm to discern shifts between meditative states. Our code base is free and open for creatives to extend and reuse. learn more

Mind Murmur programmatically senses five levels of meditation by parsing real-time EEG brain-wave data from live meditators. Five corresponding sound tracks were composed by sound-artists Julia Burke Ferguson and Dina Fisher (with creative direction by Dina).Listen Now
As a base of our analysis, we chose frontal alpha rhythm sensor readings for a baseline metric to assess the current state of a person’s mind during meditation, because the activity of alpha rhythms are proven to be associated with a state of relaxation and calmness, which characterizes the desired meditation effect.
Quantization of alpha levels into definite gradations associated with brain states is a very hard task due to a high degree of individuality in brain activity footprints. Therefore we decided to track consistency of changes in the overall alpha activity. When activity significantly increased over some period of time, indicating consistent meditation without distractions, we altered playback of thematic video, soundscape and LED-light sequences designed to indicate deeper meditation. Alternately, if there was a noticeable decrease in recent frontal alpha activity, meaning a person was likely unable to maintain concentration, we altered thematic playback to indicate shallower meditation. If no significant change in activity occurred, we did not alter thematic playback.
Our EEG band (InteraXon MUSE) measures activity levels 10 times per second. Our algorithm stores around 30 seconds of latest data at any given moment, and every 5 minutes calculates the trend of the activity for the next 30 seconds with the ARIMA model for time-series forecasting. Then logic is applied to switch between sound and visual themes according to the result of this calculation.
