The following sections list and describe the changes to Wwise between version 2017.2 and version 2017.2.1. For earlier versions, please refer to Previous Release Notes. If using the online help, you can also choose a different Wwise version from the list on top of the table of contents column.
Platform SDK updates
- Updated Perforce plug-in to Perforce SDK 2017.1.
- Xbox One XDK Updated XDK to 170601 (June 2017 QFE 3)
- PS4 SDK: Updated SDK to 5.008.041.
- Mac, iOS, tvOS: Updated to Xcode 9.1.
New Features
- WG-27339 Added support for SSL with Perforce plug-in.
- WG-36178 Spatial Audio - diffraction modeling: An additional distance multiplier is now applied to diffracted sounds. This multiplier has been added to simulate the phenomenon whereby diffracted sound waves decay faster than incident sound waves. Two new parameters have been added to the
AkSpatialAudioInitSettings to customize this behavior: fDiffractionShadowAttenFactor and fDiffractionShadowDegrees. See the for AkSpatialAudioInitSettings API documentation for more details. If, for any reason, existing sound design is negatively affected by this change, it can be disabled by setting fDiffractionShadowAttenFactor to 1.0.
- WG-36289 Spatial Audio: It is now supported to use room game objects, which are registered internally by spatial audio, as the emitter for room ambiances. Two parameter have been added to
AkRoomParams to facilitate this: RoomGameObj_KeepRegistered and RoomGameObj_AuxSendLevelToSelf. This is very useful for positioning sounds that are multi-channel ambiance 'beds' because spatial audio does all the positioning for you. Posting an Event on the room game object leverages automatic room game object placement so that when the listener is inside the room the sound comes from all around the listener, and when the listener is outside the room the sound comes from the portal(s). See the API documentation for AkRoomParams for more information on the new fields.
Behavior Changes
- WG-36119 Due to this bug introduced in 2017.2.0, and fixed in 2017.2.1, versions 2017.2.0 and 2017.2.1 will not be able to remote connect.
- WG-36287 Spatial Audio: Previously, the obstruction value from
AK::SpatialAudio::SetEmitterObstruction() was ignored when the emitter was not in the same room as the listener. Now, the maximum of the obstruction value passed from the API and the value calculated by the diffraction system is passed to the sound engine. The game is responsible for differentiating obstruction between the emitter and the portal (where SetEmitterObstruction() should be used), and occlusion from room boundaries, which is better handled by the spatial audio diffraction system. For example, games that use ray-testing for obstruction may report 100% obstruction when an object is very close to the opening of a portal because the ray between the emitter and the listener hits a nearby wall. If the game then sends 100%, this will erroneously override the diffraction angle calculation, which is probably much less than 180 degrees and better matches the expected audibility of the sound. To prevent this scenario, games can ray-test for obstruction objects between the emitter and the portal, passing the results with SetEmitterObstruction(), and then test for obstructing objects between the portal and the listener, passing the results with SetPortalObstruction().
