[UNMAINTAINED] Get a stream of audio data from the microphone on the browser or with Node!

Get a stream of audio data from the microphone.
Still TODO: browser support (see #9)! microphone-stream ought to do the trick.
Node | Browser | |
---|---|---|
Windows | NO | NO |
Linux | YES¹ | NO |
macOS | YES² | NO |
*BSD | NO | NO |
¹ requires alsa-utils
to be installed.
² requires rec
from sox to be installed.

Let's pipe our microphone input back to our speakers: feedback loop!
var mic = require('mic-stream')
var speaker = require('audio-speaker')
mic().pipe(speaker())
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.
