{{ APIRef("Web Audio API") }}

The reduction read-only property of the {{ domxref("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).

Value

A float.

Examples

js
const audioCtx = new AudioContext();
const compressor = audioCtx.createDynamicsCompressor();
const myReduction = compressor.reduction;

See BaseAudioContext.createDynamicsCompressor() for more complete example code.
