How to convert ArrayBuffer to AudioBuffer?

I am streaming an arrayBuffer to convert to an audioBuffer in order to be able to listen to it.

I am receiving a stream via a websocket event

retrieveAudioStream(){
  this.socket.on('stream', (buffer) => {
    console.log('buffer', buffer)
  })
}

the buffer is an arrayBuffer and I need it to be an audioBuffer in order to be able to listen to it on my application.

How can I do this?

Since you're streaming media rather than downloading the file and then decoding the audio data, AudioContext.createMediaStreamSource() will be much better suited for your usecase.

You can use BaseAudioContext.createBuffer() method. It is used to

create a new, empty AudioBuffer object, which can then be populated by data, and played via an AudioBufferSourceNode

See MDN for more info: https://developer.mozilla.org/en-US/docs/Web/API/BaseAudioContext/createBuffer
