Everything you need to know about acoustic frequency therapy
Solfeggio frequencies are ancient musical tones used for spiritual and healing purposes. Each frequency resonates at a specific vibration that can positively affect different aspects of mind and body.
Binaural beats work by playing two slightly different frequencies in each ear. Your brain perceives the difference as a third 'beat' that guides your brainwaves into a desired state — like focus or relaxation.
Headphones are required for true binaural beat effects since each ear needs a separate frequency. For pure tones and ambient sounds, speakers work fine.
Yes. PureHertz generates standard audio frequencies at safe volume levels. However, if you have epilepsy or are prone to seizures, consult your doctor before using frequency-based audio.
Absolutely. All audio is generated locally in your browser using the Web Audio API. No files are downloaded from servers, making it 100% private and offline-capable.
The Free version includes the tone generator, basic waveforms, and 3 presets. Pro unlocks binaural beats, all Solfeggio presets, ambient mixer, and the exponential sleep timer.
Simply click 'Open Web App' to access the full audio generator instantly. No sign-up or download required. Just press play and choose your frequency.
A native mobile app for iOS, Android, and Huawei is coming soon. For now, the web app works great on mobile browsers and can be added to your home screen.
