Binaural beats generator

How this binaural beats generator works

This binaural beats generator plays two sine tones at once: the base frequency in your left ear and the base plus a small difference in your right ear. With a 200 Hz base and a 10 Hz beat, the left ear hears 200 Hz and the right hears 210 Hz. Headphones are required — without separate left and right channels the effect cannot happen, and the two pitches simply mix in the room.

The beat value sets the difference between the ears from 0.5 Hz up to 40 Hz, and the band readout names the conventional range it falls in: delta, theta, alpha, beta, or gamma. These Greek-letter names are simply convenient labels for speed ranges used in audio and neuroscience literature — the page makes no claims about effects on sleep, focus, or health.

Using the base, beat, and timer controls

Pick a base pitch that feels comfortable — 150 to 300 Hz works well for most listeners because low tones stay gentle over long sessions. Then set a small beat: beginners often start around 10 Hz in the alpha band. The readout confirms both ears at a glance, for example left 200 Hz and right 210 Hz, so you always know the exact difference playing.

The built-in timer stops playback after the minutes you choose, up to 60, so a session ends by itself if you drift off or get absorbed in work. Start at a low volume, keep the safe limit on, and remove the headphones immediately if you feel any discomfort, pressure, headache, or urge to turn the level up.

A note on claims and safe listening

You will find large claims about binaural audio across the internet — better sleep, deeper focus, altered states. The honest position: researchers have studied these signals for decades, but evidence for reliable effects in everyday listening is limited and mixed. Treat this page as an interesting audio experiment and a precise dual-tone instrument, not a wellness treatment.

Practical safety matters more than band choice. Never use binaural tones while driving or doing anything that needs full attention, keep volumes low enough that you could hold a conversation over the sound, and prefer headphones on only in a safe, seated setting at home.

Building sessions with the timer

The timer turns an open-ended drone into a bounded session: choose 10 minutes for a short break, 30 for a long reading block, and let playback stop itself so you never have to watch the clock. Because sessions run longer than typical test tones, set the level lower than you think necessary — gentle sound that stays pleasant at minute twenty beats impressive sound that fatigues by minute five.

Keep a simple log of base, beat, and duration alongside a one-line note on how the session felt. Over weeks the notes reveal your preferences far better than band folklore does, and the habit turns casual listening into deliberate exploration. End every session by removing the headphones slowly and sitting quietly for a minute before standing up.

If a particular combination ever feels irritating rather than neutral, stop using it and try a lower base with a smaller beat — comfort is the only metric that matters for recreational listening, and no band is worth enduring.
