    A video featuring isochronic tones, a form of meditation audio, set to a slow fractal animation. The creator describes the tones as a way to settle into a quiet, deep state. That is the creator’s experience, not an established finding.

    The creator calls isochronic tones a favorite form of meditation audio and says they are effective for inducing quiet, deep states. In this video the music is also combined with amplitude entrainment embedded in the audio itself, set at 3.5 Hz to give what the creator describes as a deep delta experience. Delta is the slowest brainwave range, roughly 0.5 to 4 Hz. Research on whether rhythmic tones can shift brainwave activity or mood is still limited and mixed.

    The video itself features fractal animation. The creator finds that the visuals help deepen the meditation, because the visual stimulation relaxes the mind and lets the audio work more effectively. If you pay close attention to the animation, you will notice that it pulses inward and then outward at a very slow rate. You might try matching your breathing to this rhythm.

    Created with specialized fractal flame software, the animation comprises more than thirty-two thousand individual images, which were then converted for use in popular video formats. Post-processing was done in Sony Vegas and Photoshop, where numerous visual enhancements were made. The brainwave entrainment includes multiple layers of audio, synchronized with each other to produce the intended effect.

    These are the creator’s claims, and this audio complements rather than replaces professional care. If you have epilepsy or any other health condition, it is worth checking with your doctor before using entrainment audio.
