Ambient & Binaural Generator
betaThis free ambient generator creates binaural beats and isochronic tones with an optional noise bed — choose a frequency band (delta, theta, alpha, beta or gamma) and adjust the carrier and beat. Everything is generated on your device, so it plays for hours using no bandwidth and works offline. It is a sound generator, not a medical device.
Generate binaural and isochronic tones with a soft noise bed — an ambient soundscape created entirely on your device. It plays for hours with zero bandwidth and works offline.
8–13 Hz · relaxed/calm
Binaural beats need headphones; the isochronic pulse and noise work on speakers.
This is a sound generator, not a medical device. Evidence for health effects of binaural/isochronic tones is limited and mixed. Start at a low volume and don’t use while driving.
How to use Ambient & Binaural Generator
- 1 Pick a frequency band, or set the carrier and beat yourself.
- 2 Toggle the binaural, isochronic and noise-bed layers and set the volume.
- 3 Use headphones for the binaural beat (the isochronic pulse works on speakers).
- 4 Optionally set a sleep timer, then press Play.
Frequently asked questions
Do binaural beats need headphones?
Yes. A binaural beat is created by your brain reconciling two slightly different tones, one in each ear, so it only works with headphones. The isochronic pulse and noise bed work on speakers.
Do binaural beats actually work?
The evidence for effects on focus, relaxation or sleep is limited and mixed. This tool is a sound generator, not a medical device — enjoy it as ambient sound and set your own expectations.
Does it stream or use data?
No. The tones are generated on your device with the Web Audio API, so an hours-long session uses zero bandwidth and works offline.
What do delta, theta and alpha mean?
They are frequency ranges for the beat: delta is slowest (0.5–4 Hz), through theta and alpha, up to beta and gamma. Pick one as a starting point and adjust to taste.
