The threshold property of the {{ domxref("DynamicsCompressorNode") }} interface is a k-rate {{domxref("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.

Value

An {{domxref("AudioParam")}}.

[!NOTE] Though the {{domxref("AudioParam")}} returned is read-only, the value it represents is not.

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

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