Exploring the potential of neurofeedback and sonic neurotechnology for the
research of expanded awareness. The project combines brainwave measurement, scientific
signal processing, generation of binaural beats and live interaction of the human mind
in a continuous neurofeedback loop.
audio
The objective of BrainEcho is an online application with a full neurofeedback loop.
Nevertheless, the audio samples recorded during the BrainEcho sessions can also be
listened to offline for relaxation or exploration.
