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);
