Decode an audio file (using fluent-ffmpeg) to make an object stream where each chunk is an AudioBuffer.
npm install ffmpeg-audiobuffer-streamThen run,npm i ffmpeg-audiobuffer-stream
import {decode} from 'ffmpeg-audiobuffer-stream'const sampleRate = 44100 // Hz
const numberOfChannels = 2 // stereo
let audioStream = decode('path/to/my/audio/file.mp3', sampleRate, numberOfChannels)
audioStream.on('data', chunk => {
// Chunk is a WebAudioAPI AudioBuffer object containing a small frame of audio.
})
// Alternatively, pipe to a writable AudioBuffer object-stream.
audioStream.pipe(myAudioWritableStream)
