Welcome to use the "naturalstreaming" soundscape generator. Our design attaches great importance to the aesthetic function of hearing. It will enable you to experience the imagination of multiple worlds created from hearing to vision. Our auditory stimulation has two kinds of extension: one is the sound wave from the objective physical world, and the other is the mapping from our subjective feelings. The combination of the two will produce various wonders in the brain: streams, cicadas, echoes of empty valleys......And even the universe.
