node-osx-audio's Introduction

osx-audio

A library that provides access to Mac OS X Audio I/O as streams. Only input is supported so far.

Audio captured is Signed 16-bit PCM, Stereo, 44100Hz, in little-endian byte-order. Alternate capture modes will be supported in future versions.

Installation

To install the module for use in your projects:

npm install osx-audio

Usage

Pipe input to a writeable file stream:

var fs = require('fs');
var audio = require('osx-audio');

var input = new audio.Input();

var writable = fs.createWriteStream('output.wav');
input.pipe(writable);

Options

None yet.

API

audio.Input()

Creates a readable stream from the system audio's selected input.

Environment Variables

None yet.

Known Issues

Opening, closing, then opening an input will fail to open. Re-instantiating works fine.

Contributing

Feel free to send pull requests! I'm not picky, but would like the following:

Write tests for any new features, and do not break existing tests.
Be sure to point out any changes that break API.

History

v1.0.0
Ports native bindings to nan, newly supporting the latest Node.js versions. Huge thanks to Alexander Kuznetsov for this contribution!
v0.2.0
Reimplements streams (again) and fixes stuttering bugs. Exposes audio event emitter directly if you wanted to use it.
v0.1.0
Reimplement streams and change API.
v0.0.2
Fixup stream resume crash.
v0.0.1
Initial Release. Only input is supported.

Problems installing osx-audio

Hi,

I am a completely noob using npm... I tried to install osx-audio and the process failed as you can see below:

I followed the recommendation and I checked that npm and node were updated. Is it a local problem with my environment or something else?.

Thanks.

Port c++ bindings to Nan

Found out that node-midi did this already (also, check the two following commits [https://github.com/justinlatimer/node-midi/commit/e53396be77e699dc72fa320f6a21ddbb32ac8fbe] and [https://github.com/justinlatimer/node-midi/commit/6048bb747b995161a6f2479d0dff6aba8e2c06c9]) so, since node-osx-audio bindings are based on that project's, it should be somehow straightforward to do this.

The only thing bothering me (for now) is the node::Buffer stuff. It's not based on node-midi, so I have no reference to port it.

@fardog, do you have any ideas/comments to this?

Does not compile on Node v4.2.1

I'm sorry I don't have more time to figure this out, but I'm not a Node person (just using this library for the chromecast-osx-audio package), and I've managed to get this working by just using the Node version specified in the Readme.

npm WARN engine [email protected]: wanted: {"node":">=0.10.30 <0.12"} (current: {"node":"4.2.1","npm":"2.14.7"})

Not working on node@10

I've got reports on fardog/node-chromecast-osx-audio#15 that the C++ extensions are failing to compile on node v10. with any luck just the nan version needs to be updated, but I don't have the hardware to develop this library any longer. stacktrace from that issue is:

More information as I figure this out; it's rare, and it can happen right at start or 3 hours into the stream.

Feature request: option to select audio device

Thanks for this great package. Worked as described. But I am dearly missing an way to:

inspect which audio devices are available on the Mac
select on of those

We're trying to hook into the audio chain of a digital audio workstation, and setting the mic input device as the default input just to route to this package seems a bit odd and impractical. Is there any chance to extend this?

Of course, it would also be cool if you could select an output device directly. This would free you from using additional tools like Soundflower. But being able to select the input device is nearly a "must-have" in our case.

how to play file?

I have VLC, is there anyway to play the file or save as .mp3 or .ogg?

Wav file is not readable

Hi there,

I'm running node v0.10.38 and when I execute the little example script you provide, a wave file is being generated but it doesn't appear to be readable by audio players.

Any ideas?

Strange noises, time compression at beginning of stream

This is due to the new streams implementation. Should play clean audio at the start of the stream.
