Tone.Meter

↳ EXTENDS Tone.AudioNode

Tone.Meter gets the RMS of an input signal with some averaging applied. It can also get the raw value of the input signal.

CONSTRUCTOR

new Tone.Meter (
smoothing
)
smoothing

The amount of smoothing applied between frames.

type: Number

DEFAULTS

{
smoothing : 0.8
}

var mic = new Tone.UserMedia().open();
//connect mic to the meter
mic.connect(meter);
//the current level of the mic input in decibels
var level = meter.getValue();
