The Isochronic Tone Generator does just what it says: You can create any Isochronic Tone (between 0.01 and 50Hz) with a carrier between 50 and 999Hz. You can also mix the tone with your own music, set the wave volume in the mix, set a timer (up to 59 mins), program target isochronic frequencies for your brain entrainment sessions, use presets to start easy entrainment sessions and memory slots to put your favorite tones. As simple as it gets... Enjoy! FEATURES: ======= * Variable carrier tone * Variable isochronic tone * Fine tune for carrier, isochronic and target frequencies * Mix the tone with your own music * Wave volume for better mixing * Timer (up to 59 minutes) * Entrainment sessions: Just set the target frequency using the black indicator below the isochronic tone. * Presets (sleep, relax, awake and meditate) * Memory slots: for having your favorite tones one tap away ------------------------ Isochronic tones are regular beats of a single tone used for brainwave entrainment. Similar to monaural beats, the interference pattern that produces the beat is outside the brain so headphones are not required for entrainment to be effective. They differ from monaural beats, which are constant sine wave pulses rather than entirely separate pulses of a single tone. As the contrast between noise and silence is more pronounced than the constant pulses of monaural beats, the stimulus is stronger and has a greater effect on brain entrainment (taken from: http://www.mindalive.com/articleeleven.htm) ------------------------- Isochronic beats are not intended to treat or cure any disease, nor should any of the subject matter presented on this app or website be taken as medical advice.

Binaural Beats Generator by Meditation Treks lets you create your own binaural beats and isochronic tones for sleep, relaxation, creativity, and focus. Binaural beats use slightly different frequencies in each ear to encourage brainwave entrainment. Research suggests this may help shift your mental state toward calm, focus, or rest. Isochronic tones use a pulsing single tone and do not require headphones. WHAT YOU CAN DO • Generate binaural beats with adjustable carrier and beat frequencies • Switch to isochronic tone mode with a swipe • Choose brainwave presets: Delta, Theta, Alpha, Beta, and Gamma • Fine-tune frequencies with sliders or enter exact values • Set session timers: 5, 11, 20, or 30 minutes • Play audio in the background while using other apps WHO IT'S FOR Whether you want to wind down before sleep, support meditation, or experiment with focus and creativity, this free tool gives you direct control over the tones you hear. ABOUT GUIDED MEDITATION TREKS This app is part of the Guided Meditation Treks family. Use it on its own, or explore how binaural and isochronic tones can support your own guided meditation practice. Use headphones for binaural beats. Isochronic tones work with or without headphones.
