Setting up Wwise LTX - Lumberyard User Guide

Setting up Wwise LTX

Open 3D Engine (O3DE), the successor to Lumberyard, is now available in Developer Preview. Download O3DE or visit the AWS Game Tech blog to learn more.

Lumberyard includes Audiokinetic Wwise LTX, which is an exclusive, free version of the Audiokinetic Wwise audio middleware. Sound designers and composers can use Wwise LTX to work independently from the engineering team and author rich soundscapes for your games.

If your game requires advanced features, you can upgrade to the full version of Wwise. For more information, see Upgrading Wwise LTX to the Full Version.
