Carrier: Binaural Beats

Support

Carrier is a binaural beat generator for iPhone, iPad and Mac. It gives you continuous control over both the beat frequency and the carrier tone, rather than a fixed menu of presets.

Common questions

Do I need headphones?

For a binaural beat, yes. The effect only exists when each ear receives its own tone. Through a speaker the two tones mix in the air and you hear a pulse instead — a real effect, but a different one.

Why does playback stop when I unplug my headphones?

That is deliberate, so a session started at bedtime does not become a room-filling drone. If you want speaker playback, turn on Continue on speakers in the app.

Does it keep playing when the screen locks?

Yes. You can also play and pause from the lock screen.

Why does the carrier tone change when I pick a different band?

Each band remembers the carrier you last used with it, and starts at a pitch suited to its beat frequency. A fast beat needs a higher carrier — at a low one the two tones drift far enough apart to be heard as an interval rather than a beat. The sliders stay free; move them wherever you like and that band will remember.

Are my settings saved?

Yes. Beat, carrier, volume, warmth and your per-band pairings all persist between sessions, on your device only.

Hearing safety

Prolonged listening at high volume can damage hearing. Set a comfortable level before starting a long session.
