Subliminal audio is a type of auditory stimulation that is designed to bypass the conscious mind and directly influence the subconscious mind.
People have used subliminal tracks to change many kinds of behavior, including to exercise more often, boost self-esteem, and even become more masculine.
The subliminal consists of two tracks, a silent recording (I change the frequency of audio to become inaudible to the conscious mind, yet picked up the subconscious) and a music recording to overlay the silent track.
It’s a discreet way to listen to “meditation” music such as binaural beats, yet have subliminal messages relaying to your subconscious.
