Want to reduce this signal? Here's how to reduce your browser fingerprint →

Audio rendering may contribute to fingerprinting, but this single signal does not prove you are uniquely identifiable and does not prove you are being tracked.

Direct answer

Audio Fingerprint Test: answer first

Run a silent browser-local Web Audio fingerprint signal check. Use the result as an observable public-signal check with stated limitations, not as an absolute guarantee.

What the Audio Fingerprint Test checks

The page uses OfflineAudioContext to render a short oscillator and compressor graph locally. It samples a small set of values and hashes them in the browser.

Offline rendering avoids speaker output and does not require microphone access.

Limitations

  • Some browsers block or restrict Web Audio in privacy modes.
  • Audio output can vary by browser engine, device, and settings.
  • The page does not compare your value with other visitors.
  • No audio signal is sent to a backend API.

Reduce exposure

What to do next

If audio fingerprinting concerns you, use browser protections that limit or randomize Web Audio surfaces.

  1. Keep privacy protections enabled in browsers that provide them.
  2. Review extension permissions for audio and script-heavy sites.
  3. Use separate browser profiles when you need different site contexts.

Supporting evidence

Use this offline Web Audio rendering signal as one browser signal, not a full verdict

Run this subtest before and after one browser/privacy setting change when you need focused evidence. For a combined IP, DNS, WebRTC, IPv6, fingerprint, and User-Agent view, use the Public Exposure Report.

BaselineRun the subtest before changing browser, extension, GPU, font, or privacy settings.
RetestChange one setting, restart the browser if needed, and rerun the same subtest.

About this checkWhat it checks, what it cannot, and how to read it

Check my browser/privacy

What this checks

Visible browser/session signals such as public route, DNS/WebRTC/IPv6 behavior, fingerprint traits, user-agent, or public IP context.

Limits

What this cannot check

It cannot certify anonymity, inspect every app, or prove that a VPN, ISP, device, or account is safe.

Read results

How to use the output

Treat results as review signals for this browser/session or public target. Re-test after one change, then use Safe Copy or notes that avoid raw identifiers.

Quick reference

Audio Fingerprint Test: what this tool does

Runs a silent local Web Audio rendering signal check.

How to use

  1. Run the test. Nothing is played through the speakers.
  2. Note the audio hash and the signal magnitude next to it.
  3. Change one browser privacy setting, run again, and see whether the values move.

What the result means

A short synthetic graph - a 1000 Hz triangle oscillator through a dynamics compressor - is rendered offline at 44100 Hz, and 24 sampled output values are hashed. Differences between browsers and devices come from how each one implements that audio maths.

Known limitations

  • OfflineAudioContext has to be available. Where it is not, the test reports unavailable rather than producing a result.
  • Only 24 sampled values feed the hash, so this is a coarse signal rather than a full audio profile.
  • Browser engine updates can change the sampled values with no change on your side.

Audio Fingerprint Test — Common Questions

What is audio fingerprinting and how does it work?

Audio fingerprinting uses the Web Audio API to generate a signal in the browser and measure how the audio processing pipeline handles it. Different audio hardware, drivers, and OS stacks process the signal slightly differently — the resulting floating-point hash is often unique per device. It works silently, without any microphone access or permission prompt.

How should I use Audio Fingerprint Test results?

Use the result to decide what to review next, make one change at a time, and retest in the same browser, network, domain, or provider context when possible.

What does Audio Fingerprint Test not prove?

It does not prove anonymity, full security, complete deliverability, full reputation cleanliness, search ranking, or AI citation. It only reports the visible signals available to this tool.
