Isochronic tones without the mystery box.
Isochronic sound switches one carrier up and down at a defined rate. Unlike a binaural beat, the pulse is already present in the acoustic signal, so ordinary speakers and a single ear can reproduce it.
A clearly encoded pulse can produce an auditory steady-state response under measurement. That mechanism is not a promise that a consumer session will create a named mental or health outcome.
Three ways into the sound
Your first complete session starts instantly. One email link unlocks two more—no card required.
Built to stay in the background
Speaker-safe by design
The modulation exists before the sound leaves the device, so the featured sessions survive speakers without relying on interaural separation.
More than one dial
Rate, carrier, depth, duty cycle, envelope, noise, harmonics, and trajectory are all disclosed because “10 Hz” never describes the whole sound.
A bounded session
Choose three minutes, nineteen minutes, or a longer descent. Every field has a designed ending rather than running as an endless stream.
