BaseAudioContext: sampleRate property

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.

Value

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

Examples

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

js

const audioCtx = new AudioContext();
// Older webkit/blink browsers require a prefix

// …

console.log(audioCtx.sampleRate);
