Free Online Frequency Sound Generator — Tone, Healing & Binaural Beats

Looking for a free frequency sound generator that covers everything in one place? ALLTOOLS is a sound frequency generator and frequency tone generator that runs entirely in your browser — no download, no sign-up required. Use it as an online tone generator to produce any pure sound from 20 Hz to 20,000 Hz, play solfeggio frequencies like 528 Hz and 432 Hz, generate binaural beats for sleep or focus, run a hearing test online, match a tinnitus frequency, and test your speakers or subwoofer — all from one frequency generator online.

What are solfeggio frequencies?

Solfeggio frequencies are a set of ancient musical tones thought to carry specific healing or transformative properties. The most searched include 528 Hz (often called the "love frequency" or DNA repair tone), 432 Hz (an alternative concert pitch said to sound more natural than the standard 440 Hz), and 963 Hz (associated with pineal gland activation and spiritual connection). Whether you approach them from a spiritual, meditative, or simply curious angle, this solfeggio frequency generator lets you play each one instantly.

Using a frequency generator for healing

A frequency generator for healing is most often used to play solfeggio tones, chakra frequencies, or binaural beats during meditation, sleep preparation, or relaxation sessions. The idea is that specific sound frequencies interact with the body and nervous system in ways that support mental and physical wellbeing. While scientific evidence varies, millions of people use these tones daily for stress relief and mindfulness. The Healing tab in this tool covers solfeggio, chakra, and binaural presets so you can explore each category without switching between different apps or websites.

How do binaural beats work?

Binaural beats occur when two slightly different frequencies are played separately in each ear — your brain perceives the difference as a rhythmic pulse. For example, 200 Hz in the left ear and 210 Hz in the right creates a perceived 10 Hz beat, which falls in the Alpha brainwave range associated with relaxed focus. Delta beats (0.5–4 Hz) are linked to deep sleep, Theta (4–8 Hz) to meditation and creativity, Alpha (8–13 Hz) to calm alertness, Beta (13–30 Hz) to active thinking, and Gamma (30–100 Hz) to peak cognition. Always use headphones — binaural beats require separate audio to each ear to function.

How to use the hearing test

The online hearing test sweeps from 20 Hz upward. Keep the volume at a comfortable level — not loud. Press Stop the moment you can no longer hear the tone and your last audible frequency will be recorded. Healthy young adults typically hear up to 18–20 kHz; this range naturally narrows with age. The test is for reference only and is not a substitute for a professional audiological evaluation.
