The reduction
read-only property of the DynamicsCompressorNode
interface is a float representing the amount of gain reduction currently applied by the compressor to the signal.
Intended for metering purposes, it returns a value in dB, or 0
(no gain reduction) if no signal is fed into the DynamicsCompressorNode
. The range of this value is between -20
and 0
(in dB).
Syntax
var myReduction = compressorNodeInstance.reduction;
Value
A float.
Example
var audioCtx = new AudioContext(); var compressor = audioCtx.createDynamicsCompressor(); var myReduction = compressor.reduction;
