What Is a Browser Tone Generator?

A browser tone generator is a simple web tool that creates steady sound from inside your browser, without installing an app or downloading audio software.

The basic idea

A tone generator creates a continuous sound at a chosen frequency. In Drift Tones, the browser uses the Web Audio API to make simple sine tones. A sine tone is smooth, steady, and minimal, which makes it useful for a quiet background sound tool.

Because the sound is generated in the browser, there is no account, upload, or complicated setup. You open the page, choose a tone spacing, set the volume low, and press Start.

Why use one in the browser?

Browser tools are convenient for lightweight routines: a writing session, a short work break, a wind-down period, or a calm background while reading. They avoid the friction of downloading a dedicated app just to play a steady tone.

They are also easy to stop. Close the tab, pause the tone, or lower your device volume. That simplicity is part of the point.

What Drift Tones does

Drift Tones plays two steady tones at the same time: one in the left channel and one slightly higher in the right channel. The spacing between those two tones is labeled with common Delta, Theta, Alpha, and Beta-inspired names.

Those labels are descriptive sound settings, not medical claims. Drift Tones is a personal ambience and relaxation tool, not a treatment or health service.

A good way to start

Use headphones if you want to hear the left/right split clearly, but keep the volume low. Try one mode for a few minutes while working, reading, or winding down. If the tone feels unpleasant, stop or switch to an ambience loop instead.

Drift Tones is a personal sound and ambience tool. It is not medical advice, diagnosis, treatment, or therapy.
