audio-decode

Decode audio data from supported format to AudioBuffer.

Supported formats:

• [x] wav
• [x] mp3
• [x] ogg vorbis
• [x] flac
• [x] opus
• [ ] alac
• [ ] aac
• [ ] m4a
• [x] qoa

import decodeAudio from 'audio-decode';
import buffer from 'audio-lena/mp3';

let audioBuffer = await decode(buffer);

buffer type can be: ArrayBuffer, Uint8Array or Buffer.

Decoder's code is lazy: first run loads decoder's sources and compiles module before decoding.

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
