@tropicbliss/symphonia v0.2.19

symphonia.js

A "way too simple" cross-platform zero dependency audio playback library for Node.js

Supported Platforms

• Windows (x86-64)
• Windows (i386) (32-bit)
• macOS (x86-64)
• macOS (arm64)
• Linux (x86-64)

Supported Audio Formats

• MP3
• WAV
• Vorbis
• FLAC
• MP4
• AAC

Note

Take note that the node_modules generated by npm when installing this package is non-portable across platforms in order to save space. Thus, you'll need to run npm install when transferring your project between platforms in order for this package to work correctly (you should not be committing your node_modules anyway so for most use cases this shouldn't be a problem).

Lastly, when you call the functions for the first time it might take a few seconds for the computer to respond. This is perfectly normal behaviour as it might be caused by Windows Defender.

Usage

const axios = require('axios')
const fs = require('fs')
const symphonia = require('@tropicbliss/symphonia')

try {
  const buf = fs.readFileSync('chime.ogg') // Gets a Buffer
  symphonia.playFromBuf(buf, { speed: 1.0, volume: 1.0, isBlocking: true }) // The option object is optional. The speed and volume is both set to 1.0 and `isBlocking` is set to `true` by default.

  // You can also obtain buffers from a web request
  axios
    .get(URL)
    .then((res) => Buffer.from(res.data, 'binary'))
    .then((buf) => {
      symphonia.playFromBuf(buf)
    })

  // Play a sine wave at the frequency of 440Hz for 250ms
  symphonia.playFromSine(440.0, 250)
} catch (e) {
  console.log('Error playing audio: ', e)
}

Note that calling playFromX() without setting the isBlocking option parameter blocks the main thread by default, so pass false to isBlocking to make the methods non-blocking.

const fs = require('fs')
const symphonia = require('@tropicbliss/symphonia')

function playStuff() {
  const buf = fs.readFileSync('chime.ogg')
  const data = symphonia.playFromBuf(buf, { isBlocking: false })
  console.log("I'm not done yet, do something else to prevent this program from exiting!")
  data.controller.pause()
  data.controller.play()
  data.controller.stop()
}

try {
  playStuff()
} catch (e) {
  console.log('Error playing audio: ', e)
}
