Get an audio stream from your microphone!
npm install mic-stream> Get a stream of audio data from the microphone.
Still TODO: browser support!
microphone-stream ought to
do the trick.

Let's pipe our microphone input back to our speakers: feedback loop!
``js
var mic = require('mic-stream')
var speaker = require('audio-speaker')
mic().pipe(speaker())
`
`js`
var mic = require('mic-stream')
Creates a new audio-through stream
from the local microphone. If on the browser, the user may be first asked for
permission.
format is an object that decides the format of the audio data received. It
takes a wide variety of parameters. These are defaults:
`
{
signed: true,
float: false,
bitDepth: 16,
byteOrder: 'LE', // or BE, if you're on a big-endian system
channels: 2,
sampleRate: 44100,
interleaved: false,
samplesPerFrame: 44100,
sampleSize: 2,
id: 'S_16_LE_2_44100_I',
max: 32678,
min: -32768
}
The returned stream can be treated like a regular Node stream and piped
where ever you'd like.
Stops the microphone stream. cb is called when the process is fully stopped.
With npm, run
`
npm install mic-stream
For browser use you'll need a tool like browserify.
Node users will need a working install of sox.
