BaseAudioContext.sampleRate - Web APIs 编辑

The sampleRate property of the BaseAudioContext interface returns a floating point number representing the sample rate, in samples per second, used by all nodes in this audio context. This limitation means that sample-rate converters are not supported.

Syntax

baseAudioContext.sampleRate;

Value

A floating point number indicating the audio context's sample rate, in samples per second.

Example

Note: for a full Web Audio example implementation, see one of our Web Audio Demos on the MDN Github repo, like panner-node. Try entering audioCtx.sampleRate into your browser console.

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

...

console.log(audioCtx.sampleRate);
