Failing to instantiate a Writer/Writable object

[enahsor]

Hi. I'm testing out this package on the browser. My plan is to use it to facilitate my use of socket.io in sending audio data to the client from a server to be played. I'm unable to create an instance of either Writer/Writable.

import {Writer} from 'web-audio-stream'

const ctx = new AudioContext()
const write = Writer(ctx.destination, {samplesPerFrame: 1024})

I'm simply replicating the code from the README and yet I'm getting:
ERROR

 Argument should be an AudioBuffer instance.
    at validate (index.js:76)
    at Object.pad (index.js:365)
    at shift (write.js:128)
    at ScriptProcessorNode.<anonymous> (write.js:154)

Am I doing something wrong here? Thanks in advance.
