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