Pluck a string and see how long it sustains before falling below the threshold. Use it to compare setups, strings, guitars, or picking spots objectively.

How to use: Click Start, allow mic access, then pluck a note. The meter starts timing when it hears the attack and stops when the level drops below the threshold. Adjust the threshold slider to ignore quiet room noise.
