Hi. I have been experimenting gnaural for a few days now. But I don't get it yet. I want two different tones in each of my earphones to sense ra resulting low-frequency beat in my brain. That I think is the real concept of binaural sound. Each phone playing a pure sine wave. Taking off one earphone the binaural beat tone disappears and your hear a single frequency on the other earphone. I have used an Android app for meditation what uses binaural effects for a long time, and there you can notice...
