A FEW USEFUL DETAILS
Listen with curiosity.
How do the three sound methods differ?
Binaural audio sends different frequencies to your left and right ears, so it needs stereo headphones. Monaural audio mixes both tones into each channel. Isochronic mode rhythmically changes a carrier’s volume; this lab uses smooth pulses for a gentler sound. Monaural and isochronic modes can also be heard through speakers.
With a centre carrier of 200 Hz and a beat of 10 Hz, binaural mode plays 195 Hz on the left and 205 Hz on the right. Harmonic layers add quieter carrier pairs at multiples of the centre frequency, keeping the same beat difference.
What do alpha, theta, delta and gamma mean here?
They are familiar labels for frequency ranges. Our buttons select 10, 6, 2 and 40 Hz respectively. The numbers describe the audio we generate. The lab does not measure your brain activity or verify a particular state of consciousness.
Responses to binaural audio vary. These sessions are for listening and meditation practice, with no guarantee of sleep, lucid dreams, out-of-body experiences or medical benefits.
Can I use this on my phone?
Yes, in a browser that supports Web Audio. Keep this page open during your session. Some phones pause browser-generated audio when the screen locks or another app takes over; press Resume if that happens. Reliable background playback and offline access are planned for the dedicated mobile app.
Where are my sessions and notes saved?
Only in this browser on this device. There is no account or cross-device sync in this beta. Clearing browser data may erase them. Use Export backup to keep a copy, then Import backup on another device. Backups include your personal notes.
Comfort and listening
Start quietly and increase the volume only if needed. A higher volume is not a stronger meditation. Pause or stop if the sound feels uncomfortable. Stereo processing or a mono-audio setting can alter the left/right separation; use the ear tests to check your setup.
