Choose the carrier
The carrier is the audible pitch around which the left and right tones are placed.
BINAURAL BEAT GUIDE
More than a fixed-frequency generator.
Sineward is a free online binaural beat generator for people who want more than a fixed frequency and a play button. Shape the beat, carrier, volume, stereo position, and supporting sound layers across a visual timeline.
Open the full composer →More than a single-frequency generator
A basic binaural beat generator sends one tone to the left ear and a slightly different tone to the right. The difference between those tones is perceived as a rhythmic beat. That is useful for quick experiments, but a long listening session can benefit from more deliberate movement.
Sineward treats the session like a small multitrack audio project. You can begin with one beat frequency, transition gradually to another, change the carrier pitch, bring background texture forward or backward, and control the overall level without cutting the sound into separate files.
The composition stays editable. Save the project when you want to revisit the schedule, or render an MP3 when you want a portable listening copy.
How to generate a binaural beat in Sineward
The composer opens with a binaural voice, brown-noise layer, and field-recording layer. Start from that mix or remove anything you do not need.
Set the beat frequency
The beat is the difference between the two ear frequencies. For example, 196 Hz and 204 Hz create an 8 Hz difference.
Shape the timeline
Add automation points and drag them to create gradual or linear changes during the session.
Build the sound bed
Mix brown, pink, white, or ocean-shaped noise with bundled ambience or your own audio.
Preview and export
Listen with headphones, adjust at the playhead, and export when the balance feels comfortable.
What you can shape
Carrier frequency controls the audible pitch. Beat frequency controls the left-to-right difference. Layer volume and pan determine how supporting sounds sit around the binaural voice, while master automation shapes the overall level of the session.
Sineward also supports independent binaural voices, isochronic pulses, alternating stereo pulses, generated noise, bundled field recordings, and uploaded audio. Every sound layer remains visible in the same timeline so the relationship between the mix and its automation is easier to understand.
Listen carefully and keep expectations grounded
Stereo headphones are required for clear binaural separation because each ear must receive its own tone. Begin at a low volume and stop if the sound becomes uncomfortable. Do not listen while driving, cycling, operating equipment, or doing anything that requires full attention.
Sineward is a creative sound instrument, not a medical device. People use binaural audio during focus, calm, meditation, and rest routines, but experiences vary and the software does not diagnose, treat, prevent, or guarantee improvement of any condition.
COMMON QUESTIONS
Clear answers before you listen.
Do binaural beats require headphones?
Yes. Stereo headphones keep the left and right tones separated so the frequency difference can be perceived as a binaural beat.
Can I make the frequency change during a session?
Yes. Add automation points to the beat or carrier curve and choose smooth or linear transitions between them.
Can I download the result?
Yes. Free accounts include limited standard-quality MP3 exports; Pro supports unlimited 320 kbps exports and longer sessions.
Does Sineward upload my project audio?
The current composer stores project data and imported audio locally in your browser. Accounts are used for identity and billing, not cloud project storage.
