I'm trying to get a continuous stream of input from my microphone using the node-microphone. However, after i get my first buffer, it stops reading. Does the info event pick up all the audio, or this buffer for something else?

const stream = require('stream');
const fs = require('fs');
const mkfifo = require('mkfifo').mkfifo;
const writestream = fs.createWriteStream('audiopipe');

let Mic = require('node-microphone');
let mic = new Mic();
let micStream = mic.startRecording();
micStream.pipe( writestream );
setTimeout(() => {
    console.log('stopped recording');
    mic.stopRecording();
}, 5000);
mic.on('info', (info) => {
	console.log(info);
});
mic.on('error', (error) => {
	console.log(error);
});

Any ideas?

Is it possible to provide a live streaming to the user through this?
I've tried the following code

var Mic = require('node-microphone');
var mic = new Mic();

app.get('/testmic',function(req,res) {
	var micStream = mic.startRecording();
	micStream.pipe(res);
});

when I directly pointed to this address (localhost:4000/testmic) the stream is getting downloaded as some file.
But I want it such that when I assign this url to a audio src attribute in HTML5 audio element, I should be able to listen to the stream.

Is it possible? If yes, where have I done the mistake?

Currently this module only allows for the default device to be used on Windows.

I am trying to detect the sound of multiple audio inputs ... Is this possible?

I am trying to run the node-microphone example on my Windows 10 machine.
It is crashing with the following error

SoX is installed and added to the Environment Path

`events.js:160
throw er; // Unhandled 'error' event
^

How can I fix this ?

On Raspberry PI I am having the following issue:

/node_modules/node-microphone/index.js:6
class Microphone {

Do you know what I am doing wrong ?

This is how the constructor options documentation appears:

Create a new Class of the microphone module. You can give an options Object with the class. options - JSON containing sound options.Following are valid options: endian: big OR little, default: little bitwidth: 8 OR 16 OR 24 OR anything valid supported by arecord OR sox, default: 16 encoding: signed - integer OR unsinged- integer(none of the other encoding formats are supported), default:signed - integer rate: 8000 OR 16000 OR 44100 OR anything valid supported by arecord OR sox, default: 16000 channels: 1 OR 2 OR anything valid supported by arecord OR sox, default: 1(mono) device: hw: 0, 0 OR plughw: 1, 0 OR anything valid supported by arecord. For sox it is taken as waveaudio drive.

How can I test my MIC ? nothing happens with
pi@Rose:~/node/node_modules/node-microphone $ node index.js
