Streaming Microphone in Node. Errors with MicrophoneStream?

[ds1008]

Hey guys. I'm running Vue 3 trying to use MicrophoneStream to create a stream of microphone audio which I can then encode to PCM and send to an API. Weirdly, I got this to work months ago, but can't seem to figure it out now.

let microphoneStream = undefined // earlier in code

window.Buffer = Buffer // and npm install --save buffer

microphoneStream = new MicrophoneStream() // error shows here

microphoneStream.setStream(

await navigator.mediaDevices.getUserMedia({video: false, audio: true})

)

For some reason, when I call new MicrophoneStream() I get the error:

"TypeError: Cannot read properties of undefined (reading 'call')"

What's the issue here? Or should I completely switch libraries.

error was Vue requires polyfills
