Convert mp3/wav audio data to AudioBuffer.
const decode = require('audio-decode');
const buffer = require('audio-lena/mp3');
//as a callback
decode(buffer, (err, audioBuffer) => {});
//as a promise
decode(buffer).then(audioBuffer => {}, err => {});let promise = decode(source, {context}?, (err, audioBuffer)=>{}?)
Decode source, based on options and fire callback when done, or resolve a promise if no callback passed. Source type can be: ArrayBuffer, ArrayBufferView, Buffer, Blob, File or data-uri string.
options may include context property for web-audio-api context (browser-only). By default new audio-context is created.
Browser version uses decodeAudioData method, in node the aurora is used.
Shipped by default:
- wav via wav-decoder
- mp3 via aurora mp3
To enable additional format, install it as a dependency npm install --save flac.js and require once require('flac.js').
Additional formats available:
// Decode flac
let decode = require('audio-decode')
let flac = require('audio-lena/flac')
require('flac.js')
decode(flac).then(audioBuffer => {
//buffer is ready here
