DynamicsCompressorNode: threshold property

View on MDN ↗

The threshold property of the DynamicsCompressorNode interface is a k-rate AudioParam representing the decibel value above which the compression will start taking effect.

The threshold property’s default value is -24 and it can be set between -100 and 0.

The threshold attribute has no effect on signals lowers than its value, but induce volume reduction on signal stronger than its value.

Value

An AudioParam.

[!NOTE] Though the AudioParam returned is read-only, the value it represents is not.

Examples

const audioCtx = new AudioContext();
const compressor = audioCtx.createDynamicsCompressor();
compressor.threshold.value = -50;

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