About

OSCION

Features
Read full description

Oscion is an intuitive, interactive real-time generator for binaural beats and pure tones. Two ways to listen: Binaural beats (headphones recommended) Binaural beats are an auditory effect that can occur when each ear hears a steady tone that is slightly different in pitch. Your brain may perceive a subtle beat at the difference between those tones. Because each ear needs its own tone, headphones are recommended. Pure tones (headphones or speakers) Set the beat frequency to 0 Hz to produce a single steady tone. This does not rely on a left/right difference, so it works through speakers or headphones. Clean, precise control: Oscion is designed for direct experimentation. β€’ Adjust beat frequency and base frequency in real time. β€’ Set a session length with the built-in timer so you don’t need to watch the clock. β€’ Use the Transition feature to glide smoothly from your current tone to a different tone over a chosen duration. β€’ Listen to Oscion on its own or while other audio is playing. Presets: Oscion includes binaural beat and solfeggio frequency presets along with the ability to create and save your own custom presets. No internet connection required: Oscion does not require an account and does not stream audio from a server. Everything runs locally directly from your device.
