import decodeAudio from 'audio-decode';
import buffer from 'audio-lena/mp3';
let audioBuffer = await decode(buffer);buffer type can be: ArrayBuffer, Uint8Array or Buffer.
decode is lazy: first call prepares decoder.
To get more granular control over individual decoders, use decoders:
import decode, {decoders} from 'audio-decode';
await decoders.mp3(); // load & compile decoder
const audioBuffer = await decoders.mp3(mp3buf); // decode- wasm-audio-decoders – best in class compact & fast WASM audio decoders.
- Web Audio Decoders – native decoders API, hope one day will be fixed or alternatively polyfilled.
- decodeAudioData – default in-browser decoding method.
- ffmpeg.wasm – ultimate encoding/decoding library (8.5Mb of code).
