Decode Ogg Opus audio to PCM samples with libopus WASM.
import decode, { decoder } from '@audio/decode-opus'
let { channelData, sampleRate } = await decode(opusBytes)
let dec = await decoder() // initialize WASM
let a = dec.decode(chunk1)
let b = dec.decode(chunk2)
let tail = dec.flush()
dec.free()
decoder() is asynchronous. Its decode() and flush() methods are synchronous. flush() ends the stream.
Metadata
Read OpusTags metadata and cover art without decoding audio:
import { parseMeta } from '@audio/decode-opus/meta'
let { meta, sampleRate } = parseMeta(opusBytes)
// meta: { title, artist, album, year, genre, ..., pictures }
