attack cljs

(attack this)

Property.

[Read Only]

An web.audio.AudioParam.

var audioCtx = new AudioContext(); var compressor = audioCtx.createDynamicsCompressor(); compressor.attack.value = 0;

constructor cljs

(constructor & args)

Constructor.

The DynamicsCompressorNode() constructor creates a new web.audio.DynamicsCompressorNode object which provides a compression effect, which lowers the volume of the loudest parts of the signal

context A reference to an web.audio.AudioContext. options Optional Options are as follows:

attack: The amount of time (in seconds) to reduce the gain by 10dB. Its default value is 0.003. This parameter is k-rate. Its nominal range is [0, 1]. knee: A decibel value representing the range above the threshold where the curve smoothly transitions to the "ratio" portion. Its default value is 30. This parameter is k-rate. Its nominal range is [0, 40]. ratio: The amount of dB change in input for a 1 dB change in output. Its default value is 12. This parameter is k-rate. Its nominal range is [1, 20]. release: The amount of time (in seconds) to increase the gain by 10dB. Its default value is 0.250. This parameter is k-rate. Its nominal range is [0, 1]. threshold: The decibel value above which the compression will start taking effect. Its default value is -24. This parameter is k-rate. Its nominal range is [-100, 0].

reduction cljs

(reduction this)

Property.

[Read Only]

The reduction read-only property of the web.audio.DynamicsCompressorNode is a float representing the amount of gain reduction currently by the compressor to the signal.

var myReduction = compressorNodeInstance.reduction;
