Usage context

A useful tool with clear limits and visible documentation

This page builds more trust when it explains what the detector does, when it is useful and where to review privacy, help and usage conditions before enabling the microphone.

How to get a steadier reading

  • Use a low-noise environment and move the microphone closer to the sound source.
  • The detector responds better to sustained notes than to short or clipped sounds.
  • It is best to test on the same device and browser you will actually use for practice.

Permissions and privacy

  • The site requests microphone access only when you enable the detector.
  • The current reviewed version of the project does not upload or publish user audio recordings.
  • If the browser blocks the microphone, the tool cannot calculate the note in real time.

What this tool does not promise

  • It does not replace lessons, ear training or professional musical assessment.
  • Accuracy depends on the browser, microphone and audio environment.
  • It does not guarantee the same result on every device or usage context.
