What BinauralHQ is and why we built it
A free binaural beats generator built for curious listeners, not subscribers.
BinauralHQ started from a simple frustration: most binaural beats apps either lock the good frequencies behind a subscription or drown you in promises that the research does not actually support. We wanted a tool that does one thing well - generate clean binaural beats and isochronic tones in your browser - and is upfront about what brainwave entrainment can and cannot do.
Everything here runs locally using the Web Audio API. When you choose a carrier frequency and a beat frequency, your browser synthesizes the two tones in real time and sends a slightly different pitch to each ear. Nothing is pre-recorded, nothing is uploaded, and there is no account to create. Pick a brainwave preset - delta for sleep, theta for meditation, alpha for relaxed focus, beta for concentration, or gamma for short bursts of intensity - put on a pair of stereo headphones, and press play. If you would rather use speakers, switch to isochronic mode and the tool pulses a single tone instead.
BinauralHQ is for students looking for a steady study soundtrack, meditators who want a theta backdrop, people winding down before bed, and anyone simply curious about whether brainwave entrainment does anything for them. You do not need to know the science to use it, but if you want the details, our science page lays out the supportive studies alongside the inconvenient ones.
We think the honest answer to "do binaural beats work?" is "sometimes, for some people, for some goals." Research on anxiety reduction and relaxation looks promising; results for attention and intelligence are mixed and occasionally negative. We cite the real studies, acknowledge the limitations, and let you experiment with realistic expectations. BinauralHQ is not a medical device and nothing here is a substitute for professional care - it is a free tool for relaxation, focus, and personal exploration.
BinauralHQ is one of several free, browser-based sound tools we maintain. If pure ambient sound suits you better than entrainment, you might prefer the steady masking of Focus Hum, the meditation drones of OmTones, or the precise tone testing of TestTones. All of them share the same idea: useful audio tools that are free, require no signup, and run entirely in your browser.
