# mic-stream
> Get a stream of audio data from the microphone.
---
## Unmaintained
This module is old and doesn't seem to work any longer, and I don't have capacity / interest in maintaining it. Please consider using [node-record-lpcm16](https://github.com/gillesdemey/node-record-lpcm16/) instead.

[](https://www.npmjs.com/package/mic-stream)
## wip disclaimer
**Still TODO**: browser support (see #9)!
[microphone-stream](https://github.com/saebekassebil/microphone-stream) ought to
do the trick.
## support
| | Node | Browser |
|---------|------|---------|
| Windows | NO | NO |
| Linux | *YES*¹ | NO |
| macOS | *YES*² | NO |
| *BSD | NO | NO |
¹ requires `alsa-utils` to be installed.
² requires [`rec` from *sox*](http://sox.sourceforge.net/) to be installed.
Like to see your platform supported? Take a look at the source and consider
submitting a PR!
## example
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())
```
## api
```js
var mic = require('mic-stream')
```
### var stream = mic(format={})
Creates a new [audio-through](https;//github.com/audio-lib/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.
### stream.stop(cb)
Stops the microphone stream. `cb` is called when the process is fully stopped.
## install
With [`npm`](http://npmjs.org/), run
```
npm install mic-stream
```
For browser use you'll need a tool like [browserify](https://browserify.com).
Node users will need a working install of [sox](http://sox.sourceforge.net).
