## What is OSCION?

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.
• Adjust beat frequency and base frequency in real time.
• Set a session length with the built-in timer so you don’t need to watch the clock.
• Use the Transition feature to glide smoothly from your current tone to a different tone over a chosen duration.
• 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.
