Founder and software developer, Antagrioin · Writes and fact-checks every page on this site

The short version, before anything else: I am a software developer, not a doctor, psychologist or neuroscientist. Nobody with a clinical qualification reviews what is published here. If you are looking for medical advice about a diagnosed condition, this site is not the right source and every health page on it says so.

What I can offer is narrower and, I think, still worth something: I build the audio engine, I read the source studies rather than the headlines about them, and I check every citation on this site against the paper it names.

Why this page exists

Health content on the open web is usually written by somebody you are never told the name of. That is a problem, because the value of a sentence like “binaural beats reduce anxiety” depends almost entirely on who is saying it and what they read before they wrote it. So rather than leave a byline hanging, this page states plainly what my expertise is, where it runs out, and how to check my work without taking my word for anything.

This is also the answer to a fair question about a site that sells an app: why should you believe a page that ends in a download button? You should not, automatically. You should be able to check it. That is what the rest of this page is about.

What I actually do here

Three separate jobs, and they are worth separating because I am much better qualified for one of them than the other two.

1. I built the audio engine — this part is my actual profession

The free web generator synthesises two sine tones in real time through the Web Audio API at your device's own sample rate, one per ear, with the beat frequency being the difference between them. The mobile app does the same thing natively, offline, plus 44 presets, isochronic pulsing, and the tools in the Frequency Lab. Generating two tones accurately and keeping them phase-stable for twenty minutes is ordinary, checkable engineering, and it is the thing I am genuinely trained to do.

It also means I know exactly what the tool does and does not do, which turns out to matter editorially. It is why the generator page tells you the oscilloscope cannot show you a binaural beat — in binaural mode each ear gets one steady tone and the beat is reconstructed in your brainstem, so it is something you hear rather than something a waveform contains. A marketing writer would have drawn the pretty pulsing wave anyway.

2. I read the primary literature — a real but limited kind of expertise

Every study named on this site, I have read, at minimum in full abstract and usually in full text, and checked against PubMed to confirm it exists and says what the page claims. That sounds like a low bar. It is not one this subject generally clears: in August 2026 I went through this site's own older pages and found citations to work that does not exist — a “Journal of Cognitive Enhancement, 2020”, an MIT memory study dated to a year it was not published, a Stanford paper with no Stanford behind it. Those pages had been on the internet for months. They are gone now, and the research hub is what replaced them.

Reading a paper carefully is not the same as being able to design one, run the statistics, or judge whether a small crossover trial with eighteen participants should change anyone's behaviour. Where the literature is thin, contradictory or underpowered — which on this subject is often — the honest move is to say so, and that is what the pages do.

3. I write the pages, and I am the one who gets them wrong

There is no editorial team here, and the site should not pretend otherwise. When a page on this site is wrong, one person wrote it and one person failed to catch it. The upside of that is that corrections do not have to survive a committee: email me the page and the sentence and it gets fixed or it gets defended, usually the same week.

How to check my work

None of the following requires trusting me:

Every efficacy claim names its study. Where a page says binaural beats have an effect on anxiety, it names Garcia-Argibay et al. (2019) and tells you the meta-analysis found a small-to-moderate effect on state anxiety — not a cure, not a percentage I made up. Search the citation. If it does not say what the page says, that is a correctable error and I want the email.
The numbers this site refuses to publish are as informative as the ones it does. There are no user counts, no download figures and no star ratings anywhere on this site, because the honest numbers are small and the alternative is to invent bigger ones. That policy cost real conversions and it is written down in the Editorial Policy.
The pages tell you when the answer is no. Binaural beats not working lists the nine reasons they might not, including the possibility that they simply do not work for you. The safety page names the groups who should not use them. The comparison pages routinely conclude that something other than our product is the better answer.
Product claims are checked against the shipping app, not the marketing copy. When the store listing and this site disagreed about how many presets exist, the site was wrong and got rewritten.

What I have written

The pages I would point a sceptical reader at first — these are the ones where the research is doing the most work:

What are binaural beats? — the foundational explainer, and the one most other pages depend on.
How binaural beats work — the neural pathway from cochlea to auditory cortex, step by step.
The research hub — the studies, read in full, with what each one actually found.
The science of binaural beats — what neural entrainment is and what the EEG evidence supports.
Are binaural beats safe? — including the epilepsy caution and who should avoid them.

The pages where the subject is genuinely contested, and where I have tried hardest not to oversell:

Binaural beats and depression and migraine — both rewritten around what the evidence actually supports, which is less than the internet suggests.
Tinnitus and chronic pain — where sound-based approaches have a real role, and a well-defined limit.
Bilateral stimulation audio — and why it is not EMDR therapy, no matter what it is sold as.
Do binaural beats release dopamine or serotonin? — a question the internet answers with far more confidence than the evidence allows.
432 Hz and the Solfeggio frequencies — a cultural and spiritual tradition, described as one, without sneering at anyone interested in it.
Binaural beats on YouTube versus an app and binaural beats for yoga — the practical, unglamorous end of the subject.

Antagrioin

Antagrioin is a small technology studio in Turkey. Brainwave Generator is its flagship product: a binaural beats app on iOS and Android, plus the free web generator that requires no account and uploads nothing. More about the studio and why it built this on the about page.

Corrections and contact

If I have misread a study, overstated a result, or cited something that does not say what I claim it says, I want to know — that is the only mechanism a one-person site has instead of an editorial board.
