Journey Builder

Design how beat frequency, carrier tone, and volume change across a timed listening session.

Changing duration preserves valid points and never silently removes automation.

Start with a preset, then open any automation lane to shape how the session changes over time.

Noise type is set to none, so the background-noise lane is silent. Choose white, pink, or brown to hear its automation.

Each preset is a construction to inspect and change. Its name describes the intended listening context, not a guaranteed outcome.

Focus Ramp

25 min

Focused work and longer study blocks

Raises the beat frequency into a sustained higher section, then eases it back while the carrier and pink noise move gently.

Parameters that change: Beat frequency, Carrier tone

Meditation Trip

15 min

A slower listening or reflection session

Moves the beat frequency down and back up over a restrained brown-noise bed, with small carrier changes.

Parameters that change: Beat frequency, Carrier tone

Theta Trance

12 min

A short, lower-frequency listening experiment

Holds a steady opening, moves into a lower beat-frequency section, then returns to the starting value.

Parameters that change: Beat frequency

Hypnagogic Dip

20 min

A gradual evening or wind-down experiment

Uses a long, slow beat-frequency dip with a steady carrier and modest pink-noise movement.

Parameters that change: Beat frequency

Deep Work Arc

27 min

An extended work session with a stable middle

Builds gradually, stays nearly unchanged through most of the session, then releases with a gentle tone fade.

Parameters that change: Beat frequency, Carrier tone, Tone volume

Slow Descent

22 min

A steady, lower-frequency listening session

Lowers the beat and carrier gradually while the tone fades in, remains steady, and fades out.

Parameters that change: Beat frequency, Carrier tone, Tone volume

Attention Reset

12 min

A short break between tasks or work blocks

Moves from a calmer opening into a higher middle section, then returns to its opening character.

Parameters that change: Beat frequency, Carrier tone, Tone volume

The basic process

How to build a journey

1Choose a preset or begin with a blank journey.
2Open an automation lane.
3Click to add points and drag them to change time and value.
4Preview the session with Play.
5Save the editable settings or download the rendered audio.

Understand the controls

Beat frequency: The frequency difference between the left and right tones in binaural mode, or the pulse rate in isochronic mode.
Carrier tone: The audible base pitch. The beat frequency is added to it to create the second binaural tone.
Tone volume: The level of the generated tone. Keep it low and comfortable, especially when using headphones.
Duration: The full length of the journey. Shortening it is blocked when automation points would be lost.
Curve type: The path between timeline points. This version uses smooth linear transitions.
Snap interval: The time grid used while placing or moving points. Turn it off for one-second positioning.
Timeline points: Time-and-value markers that define where a parameter starts, changes, and ends.

Saving, sharing, and downloading

Save stores an editable journey in this browser on this device. Clearing site data or using another browser removes access to that local copy.

Export downloads the editable journey settings as JSON. Import reads a compatible JSON file into a new unsaved copy, while Share journey file uses the device share menu when available.

Download renders the full journey as a stereo WAV on this device. Longer sessions take more time and memory, and file sharing depends on browser support.

Listening guidance

Stereo headphones are required to create the binaural effect. Isochronic mode can also be heard through speakers.

Begin at a low volume and raise it only to a comfortable level. Stop if the sound becomes uncomfortable, and do not listen while driving.

For a plain-language introduction, read Binaural Beats 101 or review the site's research summaries.

A session you can shape

Build movement into the full listening session

A standard tone generator holds its settings until you change them. The Journey Builder lets those settings move on a timeline. You can begin with a built-in preset or place your own points, then listen to the complete arc before saving it.

The frequency labels describe the beat or pulse rate being generated. They do not guarantee that a listener will enter a matching mental state. Treat each journey as a listening setup you can test during a defined activity and compare with another session.

What you can automate

Beat frequency: Shape the binaural difference or isochronic pulse rate from 1 to 40 Hz.
Carrier tone: Move the audible pitch higher or lower without changing the selected beat rate.
Tone volume: Fade the generated tone in, hold it steady, or reduce it near the end.
Background noise: Automate white, pink, or brown noise as a separate layer when noise is enabled.

Save the design or render the audio

Save keeps an editable journey in this browser. Export journey creates a JSON file containing the settings, while Download renders a stereo WAV file for offline listening.

The work happens locally on your device. Longer WAV files use more memory and storage, so a shorter test render is sensible before preparing a long session.

Journey Builder questions

What can the Journey Builder change over time?

You can automate beat frequency, carrier frequency, tone volume, and background-noise volume. Each lane uses editable points to define how the setting changes during the session.

Do I need headphones?

Stereo headphones or earbuds are needed for binaural mode because each ear receives a different tone. Isochronic mode uses a pulsing tone and can also work through speakers.

Are my journeys uploaded?

No. Playback, saved journeys, and WAV rendering stay on your device. You can export a small JSON settings file if you want to move an editable journey to another browser.
