Binaural Lab – Sleep & Relax

Measure, don't guess. Open Binaural Lab is a privacy-first binaural beats app designed for people who prefer experimentation over promises. Create customizable binaural sessions, compare frequencies, run randomized blind experiments (including placebo), and discover which settings are personally associated with better focus, relaxation or sleep. No mystical claims. No medical promises. Just your own observations. Features 🎧 Real-time binaural beat generator • Adjustable beat frequency • Adjustable carrier frequency • Custom session duration • Fade in / Fade out • White, Pink and Brown noise • Background playback • Stereo headphone detection 🧠 Ready-to-use presets Start in seconds with editable presets including: • Focus • Relax • Sleep • Creativity • Meditation Every preset can be customized before starting. 📊 Measure how you feel Rate your state before and after every session: • Relaxation • Focus • Sleepiness • Stress Over time, Open Binaural Lab builds personal statistics from your own completed sessions. 🧪 Blind experiments with placebo Reduce expectation bias with randomized listening protocols. • Randomized session order • Placebo sessions • Blind frequency assignment • Delayed reveal • Progress tracking Instead of asking "Which frequency should work?", ask "Which one works best for me?" 📈 Personal insights Explore your own results through: • Frequency comparisons • Personal trends • Session history • Average score changes • Personal vs community comparisons The app reports statistical associations—not proof that a frequency caused a change. Built on published research Open Binaural Lab follows an evidence-aware approach inspired by peer-reviewed research on binaural beats. The included presets are experimental starting points based on findings discussed in published reviews and meta-analyses while remaining fully customizable. Research referenced in the app includes: • Garcia-Argibay et al. (2019) — Meta-analysis on cognition, anxiety and pain • Ingendoh et al. (2023) — Systematic review of EEG entrainment studies • Basu & Banerjee (2023) — Meta-analysis on attention and memory • Fan et al. (2024) — Sleep research • Additional peer-reviewed publications are referenced inside the app. Current scientific evidence remains mixed, and no binaural beat frequency has been proven to reliably produce a specific mental state in every individual. Open Binaural Lab helps you explore published hypotheses and measure your own observations rather than relying on claims. Anonymous community results (optional) If you choose to contribute anonymously, you can compare your personal observations with aggregated community data. • Completely optional • Anonymous by design • Aggregated statistics only • No account required Privacy first Your data belongs to you. • No account required • Local-first storage • Anonymous participation is optional • Free-text notes never leave your device • Delete your data whenever you want Open source audio engine The binaural audio engine is open source. The application, experiment system and optional anonymous community services remain proprietary. Important Open Binaural Lab is intended for experimentation and educational purposes. It is not a medical device and is not intended to diagnose, treat, cure or prevent any medical condition. Use stereo headphones for binaural beats. Do not use while driving or performing activities requiring full attention. Stop listening if you experience discomfort.
