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

+ +
+

{{ domxref("AudioContext") }}的sampleRate属性返回一个浮点数表示采样率(每秒采样数), 同一个AudioContext中的所有节点采样率相同,所以不支持采样率转换。

+
+ +

语法

+ +
var audioCtx = new AudioContext();
+var mySampleRate = audioCtx.sampleRate;
+ +

返回值

+ +

A floating point number.

+ +

例子

+ +
+

注意:想要完整的Web Audio实例,可以查看MDN Github repo上的Web Audio Demo,比如panner-node。不妨试试在浏览器控制台输入audioCtx.sampleRate

+
+ +
var AudioContext = window.AudioContext || window.webkitAudioContext;
+var audioCtx = new AudioContext();
+// Older webkit/blink browsers require a prefix
+
+...
+
+console.log(audioCtx.sampleRate);
+
