Wwise Authoring API Reference - Functions

Refer to Using the Wwise Authoring API (WAAPI) for more information about Wwise Authoring API.

Executes an action on all nodes that are referenced in the specified event in a Play action. See AK::SoundEngine::ExecuteActionOnEvent.

Gets the current state of a State Group. When using setState just prior to getState, allow a brief delay (no more than 10ms) for the information to update in the sound engine.

Gets the current state of a Switch Group for a given Game Object.

Asynchronously post an Event to the sound engine (by event ID). See AK::SoundEngine::PostEvent.

Display a message in the Profiler's Capture Log view.

Posts the specified Trigger. See AK::SoundEngine::PostTrigger.

Register a game object. Registering a game object twice does nothing. Unregistering it once unregisters it no matter how many times it has been registered. See AK::SoundEngine::RegisterGameObj.

Resets the value of a real-time parameter control to its default value, as specified in the Wwise project. See AK::SoundEngine::ResetRTPCValue.

Seeks inside all playing objects that are referenced in Play Actions of the specified Event. See AK::SoundEngine::SeekOnEvent.

Sets the default active listeners for all subsequent game objects that are registered. See AK::SoundEngine::SetDefaultListeners.

Sets the Auxiliary Busses to route the specified game object. See AK::SoundEngine::SetGameObjectAuxSendValues.

Set the output bus volume (direct) to be used for the specified game object. See AK::SoundEngine::SetGameObjectOutputBusVolume.

Sets a single game object's active listeners. By default, all new game objects have no listeners active, but this behavior can be overridden with SetDefaultListeners(). Inactive listeners are not computed. See AK::SoundEngine::SetListeners.

Sets a listener's spatialization parameters. This lets you define listener-specific volume offsets for each audio channel. See AK::SoundEngine::SetListenerSpatialization.

Sets multiple positions for a single game object. Setting multiple positions for a single game object is a way to simulate multiple emission sources while using the resources of only one voice. This can be used to simulate wall openings, area sounds, or multiple objects emitting the same sound in the same area. See AK::SoundEngine::SetMultiplePositions.

Set a game object's obstruction and occlusion levels. This function is used to affect how an object should be heard by a specific listener. See AK::SoundEngine::SetObjectObstructionAndOcclusion.

Sets the position of a game object. See AK::SoundEngine::SetPosition.

Sets the value of a real-time parameter control. See AK::SoundEngine::SetRTPCValue.

Sets the scaling factor of a game object. You can modify the attenuation computations on this game object to simulate sounds with a larger or smaller affected areas. See AK::SoundEngine::SetScalingFactor.

Sets the State of a State Group. See AK::SoundEngine::SetState.

Sets the State of a Switch Group. See AK::SoundEngine::SetSwitch.

Stop playing the current content associated to the specified game object ID. If no game object is specified, all sounds are stopped. See AK::SoundEngine::StopAll.

Stops the current content, associated to the specified playing ID, from playing. See AK::SoundEngine::StopPlayingID.

Unregisters a game object. Registering a game object twice does nothing. Unregistering it once unregisters it no matter how many times it has been registered. Unregistering a game object while it is in use is allowed, but the control over the parameters of this game object is lost. For example, say a sound associated with this game object is a 3D moving sound. It stops moving when the game object is unregistered, and there is no way to regain control over the game object. See AK::SoundEngine::UnregisterGameObj.
Creates Wwise objects and imports audio files. This function uses the same importation processor available through the Tab Delimited import in the Audio File Importer. The function returns an array of all objects created, replaced or re-used. Use the options to specify how the objects are returned. For more information, refer to Importing Audio Files and Creating Structures.
Scripted object creation and audio file import from a tab-delimited file.

Gets the min/max peak pairs, in the given region of an audio source, as a collection of binary strings (one per channel). The strings are base-64 encoded, 16-bit signed int arrays, with min and max values being interleaved. If getCrossChannelPeaks is true, only one binary string represents the peaks across all channels globally.

Gets the min/max peak pairs in the entire trimmed region of an audio source, for each channel, as an array of binary strings (one per channel). The strings are base-64 encoded, 16-bit signed int arrays, with min and max values being interleaved. If getCrossChannelPeaks is true, there is only one binary string representing peaks across all channels globally.

Deletes the specified object.

Compares properties and lists of the source object with those in the target object.

Performs a query and returns the data, as specified in the options, for each object in the query result. The query can specify either a 'waql' argument or a 'from' argument with an optional 'transform' argument. Refer to Using the Wwise Authoring Query Language (WAQL) or Querying the Wwise Project for more information. Refer to Return Options to learn about options.

Gets the specified attenuation curve for a given attenuation object.

Connects the Wwise Authoring application to a Wwise Sound Engine running executable. The host must be running code with communication enabled. If only "host" is provided, Wwise connects to the first Sound Engine instance found. To distinguish between different instances, you can also provide the name of the application to connect to.

Disconnects the Wwise Authoring application from a connected Wwise Sound Engine running executable.

Retrieves all consoles available for connecting Wwise Authoring to a Sound Engine instance.

Sets which version of the source is being used for the specified sound. Use ak.wwise.core.object.get with the 'activeSource' return option to get the active source of a sound.

Converts the external sources files for the project as detailed in the wsources file, and places them into either the default folder, or the folder specified by the output argument. External Sources are a special type of source that you can put in a Sound object in Wwise. It indicates that the real sound data will be provided at run time. While External Source conversion is also triggered by SoundBank generation, this operation can be used to process sources not contained in the Wwise Project. Please refer to Wwise SDK help page "Integrating External Sources".

Generate a list of SoundBank with import definition defined in the WAAPI request. If you choose to not write the SoundBanks to disk, subscribe to ak.wwise.core.soundbank.generated to get SoundBank structure info and the bank data as base64.

Retrieves a SoundBank's inclusion list.

Imports SoundBank definitions from the specified file. Multiple files can be specified. See the WAAPI log for status messages.

Modifies a SoundBank's inclusion list. The 'operation' argument determines how the 'inclusions' argument modifies the SoundBank's inclusion list; 'inclusions' may be added to / removed from / replace the SoundBank's inclusion list.

Assigns a Switch Container's child to a Switch. This is the equivalent of doing a drag&drop of the child to a state in the Assigned Objects view. The child is always added at the end for each state.

Returns the list of assignments between a Switch Container's children and states.

Removes an assignment between a Switch Container's child and a State.

Creates a transport object for the given Wwise object. The return transport object can be used to play, stop, pause and resume the Wwise object via the other transport functions.

Destroys the given transport object.

Executes an action on the given transport object, or all transport objects if none is specified.

Returns the list of transport objects.

Gets the state of the given transport object.

Prepare the object and its dependencies for playback. Use this function before calling PostEventSync or PostMIDIOnEventSync from IAkGlobalPluginContext.

Begins an undo group. Make sure to call ak.wwise.core.undo.endGroup exactly once for every ak.wwise.core.beginUndoGroup call you make. Calls to ak.wwise.core.undo.beginGroup can be nested. When closing a WAMP session, a check is made to ensure that all undo groups are closed. If not, a cancelGroup is called for each of the groups still open.

Cancels the last undo group. Please note that this does not revert the operations made since the last ak.wwise.core.undo.beginGroup call.

Ends the last undo group.

Undoes the last operation in the Undo stack.

Enables debug assertions. Every call to enableAsserts with 'false' increments the ref count. Calling with true decrements the ref count. This is only available with Debug builds.

Enables or disables the automation mode for Wwise. This reduces the potential interruptions caused by message boxes and dialogs. For instance, enabling the automation mode silently accepts: project migration, project load log, EULA acceptance, project licence display and generic message boxes.

Private use only.
