Using the Wwise Authoring API (WAAPI)

The Wwise Authoring API is used to communicate with the Wwise authoring application. The functions available in the API allow the clients to perform several tasks, including:

Wwise project manipulations, such as:
- Retrieving objects and their information
- Setting information on objects
- Creating new objects
Common operations, such as:
- Importing audio files
- Generating SoundBanks
- Converting audio files
- Playing Wwise objects
User interface access and control, such as:
- Opening views
- Accessing current selection and changing them
- Inspecting objects
SoundEngine usage, such as
- Creating Game objects and setting their position
- Posting Events
- Setting Game Parameter values, Switches and States

Usage

The Wwise Authoring API can be integrated within a:

Game Engine
Dialogue management pipeline
DAW for sound design, editing, dialogue recording or music production

The Wwise Authoring API can be used to:

Automate tasks, such as importing audio files or creating Wwise objects
Remotely control Wwise on mobile devices
Implement custom Wwise interfaces

Protocols

The Wwise Authoring API is accessible through 2 different protocols:

WAMP: WAMP is intended to connect application components in distributed applications. WAMP uses WebSocket as its default transport, which allows for ordered, reliable, bidirectional, and message-oriented communications. WAMP allows the clients to call functions with JSON arguments and retrieve structured JSON results. WAMP also allows clients to subscribe to notifications.
HTTP POST: HTTP is an application protocol for distributed applications. HTTP is the most used method to transfer content on the Internet. POST enables the caller to send a document body, which, for the Wwise Authoring API, corresponds to the function arguments as JSON. The HTTP response is the JSON result.

These 2 protocols can be used under a variety of languages, such as C++, C#, JavaScript, Python, and other languages with HTTP or WebSocket support.

info

Note: WAMP provides the best performance and experience because it reuses the same WebSocket connection for the whole session and provides bidirectional communications.

In summary, here are the features supported by the protocols:

API Feature	WAMP	HTTP POST
Remote Procedure Calls Allows to call functions remotely on Wwise Authoring Refer to Wwise Authoring API Reference	Supported	Supported
Publish & Subscribe Allows to receive notifications when changes occur in the Wwise authoring.	Supported	Not Supported
Optimal performance	Yes	No
