DotWĀV is a pure tone frequency instrument and a noise generator. Every sound is generated live by your device at the exact settings you choose—nothing is streamed, nothing is compressed, and nothing is downloaded. Three kinds of tone: · Pure Tone → a single clean frequency, from the solfeggio and angelic frequencies to 432 and 440 Hz. · Binaural Beats → a slightly different frequency in each ear. Headphones required: the beat exists in the listening, not in the sound. · Isochronic Pulses → one tone, switched on and off at a steady rate, from 0.5 Hz up through the gamma band at 40 Hz. Set the frequency and pulse rate by dragging, or choose a preset. Three kinds of noise: · White Noise → every frequency at equal strength, a bright, even hiss. · Pink Noise → softer in the highs and steady, like rain on a roof. · Brown Noise → deep and low, like a distant rumble. Many people use noise to help them fall asleep. Switch between tones and noise with the Mode button. Features · Four wave visualizations: Circles, Drops, Fills, and Classic. Each one drawn live from the sound you're actually hearing. · In Noise mode, off-air TV snow in white, pink, or brown, with fine, coarse, or blotchy texture, or a plain black screen for sleep. · Full screen, edge to edge, in any orientation. · A sleep timer that fades the sound out gently rather than cutting it, with an optional end-of-timer sound: Glass, Two Notes, Bloom, or Bowl. · Random picks a new sound and a new look for you. · My Waves: save a tone or noise you like and return to it. · Plays on through screen lock and in the background, with proper lock-screen controls. DotWĀV is for entertainment and relaxation only. It is not a medical device and does not diagnose, treat, or replace professional medical care. Do not use while driving, operating machinery, or doing anything that requires your full attention. If you have epilepsy, a pacemaker, or any condition that may be affected by audio stimulation, consult a physician before use.
