audio-decode

Decode audio data from supported format to AudioBuffer.

Supported formats:

• <input checked="" disabled="" type="checkbox"> wav
• <input checked="" disabled="" type="checkbox"> mp3
• <input checked="" disabled="" type="checkbox"> ogg vorbis
• <input checked="" disabled="" type="checkbox"> flac
• <input checked="" disabled="" type="checkbox"> opus
• <input disabled="" type="checkbox"> alac
• <input disabled="" type="checkbox"> aac
• <input disabled="" type="checkbox"> m4a
• <input checked="" disabled="" type="checkbox"> 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
