node-wwriff

A port of ww2ogg. Provides a streaming decoder for Audiokinetik Wwise files to ogg packets.

Installation

npm install node-wwriff

Example

const fs = require('fs');
const ogg = require('ogg');
const { Decoder } = require('node-wwriff');
 
const encoder = new ogg.Encoder();
const decoder = new Decoder();
decoder.setCodebook("path_to_external_codebooks.bin");
 
fs.createReadStream("file.wem").pipe(decoder).pipe(encoder.stream());
encoder.pipe(fs.createWriteStream("file.ogg"));

See the examples directory for some example code.

API

Decoder class

The Decoder class is a Writable and Readable stream that accepts an wem file written to it and emits ogg_packet instances. These need to be piped into and ogg.Encoder.

Notes

This project is by no means a complete port of ww2ogg and lacks a lot of features (PRs welcome 😉), especially support for inline codebooks. It was also only tested with audio files from The Witcher 3: Wild Hunt and is probably incompatible with a lot of other files.
