What this audio tool does

Generate the auditory illusion of a tone that seems to rise or fall continuously and download it as WAV.

Octave-spaced sine layers sweep together while a smooth amplitude envelope disguises each octave wrap.

Browser results depend on device resources and supported codecs. Use short or medium files for responsive processing.

Supported formats and limits

Common MP3, WAV, M4A/AAC, Ogg, FLAC, and WebM files may work when the current browser can decode them. Recording output depends on MediaRecorder support. Generated tones export as PCM WAV.

Example and practical tips

Begin with a short, clean file so you can verify the result quickly. For analysis tools, compare the result with what you hear rather than treating one number as a final mastering decision. Keep headphone volume moderate when generating tones.

Frequently asked questions

What is a Shepard tone?

It is a layered set of octave-related tones whose changing pitch and loudness create an apparently endless rise or fall.

Is the generated sound truly rising forever?

No. Each octave cycle wraps seamlessly while overlapping layers hide the reset.

Can I download the generated tone?

Yes. The browser synthesizes a new PCM WAV file.

Why should I keep the volume moderate?

Layered tones can feel intense or fatiguing, especially on headphones.

Does the generator use an uploaded sample?

No. It creates the waveform mathematically in your browser.
