1 Hz Delta up to 15 Hz Alpha Binaural beats tone mixed together READ DESCRIPTION FIRST, Warning this Binaural beats tone produces overtones harmonics because of the sawtooth waveform so you will get a mixture of Binaural beat tones between 1 and 15 hertz from the delta to the alpha frequency brain wave. I cut of all the sawtooth frequency above 2000 hz (2 khz) with a equalizer because Binaural beats only works up to a high frequency of 1500 hz (15 khz) but lower frequency works better for Binaural beats around 50 hz to 750 hz.. This sawtooth sound plays ...From:mrshaneqViews:11 0ratingsTime:10:26More inScience & Technology
