Play/Stream/Record PCM audio data
npm install xcraft-audifyXcraft Audify.js - Play/Stream/Record PCM audio data & Encode/Decode Opus to PCM audio data
This project is a fork of https://github.com/almoghamdani/audify where the usual node-gyp is used instead of CMake, libopus has been dropped and some backends are not compiled.
- Complete API for realtime audio input/output across Linux (native ALSA and PulseAudio), Macintosh OS X (CoreAudio), and Windows (DirectSound and WASAPI) operating systems using C++ RtAudio library.
```
npm install xcraft-audify
#### Requirements for source build
- Node or Electron versions that support N-API 5 and up (N-API Node Version Matrix or a recent version of Visual C++ will do (the free Community version works well)
- MingW64
- Unix/Posix:
- Clang or GCC
#### Record audio and play it back realtime
`javascript
const { RtAudio, RtAudioFormat } = require("xcraft-audify");
// Init RtAudio instance using default sound API
const rtAudio = new RtAudio(/ Insert here specific API if needed /);
// Open the input/output stream
rtAudio.openStream(
{
deviceId: rtAudio.getDefaultOutputDevice(), // Output device id (Get all devices using getDevices)getDevices
nChannels: 1, // Number of channels
firstChannel: 0, // First channel index on device (default = 0).
},
{
deviceId: rtAudio.getDefaultInputDevice(), // Input device id (Get all devices using )
nChannels: 1, // Number of channels
firstChannel: 0, // First channel index on device (default = 0).
},
RtAudioFormat.RTAUDIO_SINT16, // PCM Format - Signed 16-bit integer
48000, // Sampling rate is 48kHz
1920, // Frame size is 1920 (40ms)
"MyStream", // The name of the stream (used for JACK Api)
(pcm) => rtAudio.write(pcm) // Input callback function, write every input pcm data to the output buffer
);
// Start the stream
rtAudio.start();
