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.
BaseAudioContext: sampleRate property
Value
A floating point number indicating the audio context's sample rate, in samples per second.

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