{{ domxref("GainNode") }} 介面的 gain 屬性是 a-rate {{domxref("AudioParam")}}，代表增益的數值。

+
+ +

語法

+ +
var audioCtx = new AudioContext();
+var gainNode = audioCtx.createGain();
+gainNode.gain.value = 0.5;
+
+ +

傳回值

+ +

一個 {{domxref("AudioParam")}}.

GainNode 介面代表的是音量改變。 這是 {{domxref("AudioNode")}} 音訊處理模組，可以對輸入的訊號做增益 (gain) 後輸出。一個 GainNode 有一個輸入和一個輸出，兩者有相同的聲道數。

+
+ +

增益 (gain) 是無單位的數值，隨時間變化，會用來和所有輸入聲道的取樣做相乘。 如果更改的話，新的增益會用 de-zippering 演算法處理，以避免輸出聲音出現難聽的「喀」聲。

+ +

The GainNode is increasing the gain of the output.
