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 read-only 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);
