BaseAudioContext: sampleRate property

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since ⁨April 2021⁩.

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);
