Drift Tones guide

What Is a Browser Tone Generator?

Browser tone generators are intentionally simple. They create steady sound directly in your web browser, usually with the Web Audio API, so you can hear a tone without installing software, creating an account, or sending audio anywhere. Drift Tones uses that idea for a narrow purpose: making a calm, repeatable listening surface for breaks, focus blocks, reading, and winding down. It is not trying to be a full music app. It is closer to a small desk lamp for sound: switch it on, set the intensity, and let it sit in the background.

The core idea

A browser tone generator starts with an oscillator, which is a tiny sound source built into modern browsers. An oscillator can create a sine wave: a smooth, steady tone with no melody, beat, lyric, or surprise. Drift Tones plays one sine tone to the left side and another slightly higher tone to the right side. The spacing between those tones is what the preset labels describe.

Why browser-only matters

Because the generator runs locally, the page does not need to upload microphone input, store audio, or create a user profile. That makes it useful as a lightweight utility: open the page, press start, and close it when finished. The tradeoff is that it is deliberately limited. You do not get a huge library, social features, or a complicated mixer.

Where Drift Tones is different

Drift Tones combines two kinds of background sound. The tone generator is precise and minimal. The ambience layer is softer and more environmental: rain, water, wind, and other loops can make the steady tone feel less sterile. You can use either layer by itself, or combine them at low volume.

Good first settings

If you are new to the tool, start with Settle / Alpha at 18% volume and the 200 Hz base tone. Try it for five minutes while reading or doing a simple admin task. If it pulls too much attention, lower the volume before changing presets. The best setting is the one that disappears into the room.

Why simple can be better

A minimal tone generator has one advantage that is easy to underestimate: it does not keep offering you choices. Many audio products are built around discovery, recommendations, favorites, and libraries. Those are useful when you want entertainment. They are less useful when the goal is to lower friction and get back to work. Drift Tones keeps the interaction small on purpose. You pick a spacing, set the volume, and let the sound be boring enough to help.

What happens in the browser

When you press start, the page creates two oscillator nodes and routes them to the left and right channels. The browser sends that audio to your normal output device, just like any other page. Changing the base frequency moves both tones together. Changing the preset changes the distance between them. The controls are visible because hidden audio settings are frustrating when a sound feels slightly wrong.

Best uses

This kind of tool works best for small rituals: a five-minute reset, a reading block, a writing sprint, a quiet admin sweep, or a wind-down cue at the end of the day. It is not meant to replace music, meditation apps, professional audio tools, or long-form ambience libraries. It fills the gap between silence and “too much.”
