The microphone is asked for only when you press Start, and heard only while the tuner is on. Nothing is recorded or sent.
How to tune an 8-string bass
- Press Start tuning and allow the microphone when your browser asks. A quiet room helps.
- Play one string, open, and let it ring. The tuner names the note it hears and the string it is nearest.
- If the needle is left of the middle, the string is low (flat): tighten it. If it is right of the middle, it is high (sharp): loosen it. Turn a little at a time, and play the string again.
- When the needle sits in the middle and the note turns green, that string is in tune. Go on to the next.
- Tune each string up to its note rather than down to it: the string holds its tuning better. Check them all once more at the end, because tuning one pulls a little on the others.
No microphone? Click a string above to hear its note, tick Keep playing the string I click, and turn the peg until your string and the note sound the same, with no slow wobble between them.
