How to use it
- Tap Start listening
Allow the microphone when the browser asks.
- Make or find the sound
Hold the microphone near it. The tall peak is the strongest pitch.
- Freeze it
Freeze keeps the picture still. Peak hold keeps the loudest level of each pitch.
Tips
- Mains hum
A hum shows at 50 or 60 Hz, depending on your country, and at its multiples.
- One squeal, one peak
A whistle or a squealing belt shows a single tall peak. Its pitch helps find the part.
- Low and high ends
Small microphones hear little at the very low and very high ends.
