Wwise SDK 2018.1.11
What's New in 2008.4 ?

The following sections list and describe the changes made to the Wwise SDK between version 2008.3 and version 2008.4

Changes that were also provided in patches over 2008.3 are shown in italics.

API Changes

  • WG-6970: Reworked the Low-Level I/O API, specific to the default implementation of the Stream Manager. It is now cross-platform, and some heuristics are passed down to the Low-Level I/O system. Coupled with asynchronous low-level I/O handshaking, it allows for tighter integration with the game regarding I/O. (Low-Level I/O). Note that you may keep your current streaming integration with little effort. See the note in Streaming / Stream Manager.
  • WG-12375: I/O pool attributes were added to the user-defined device settings (AkDeviceSettings, in AkStreamMgrModule.h).
  • WG-8476: Added GetDefaultSettings() and GetDefaultDeviceSettings() to the default Stream Manager's specific definitions. Simplifies initialization of the Stream Manager and I/O system. (Initializing the Streaming Manager).
  • WG-8656: Added one argument to AK::IAkStreamMgr::Create[Std|Auto]: in_bSyncOpen. When it is false, the Low-Level I/O is allowed to perform an asynchronous file open. This argument is passed (and was added) to Open() in the Low-Level I/O. (IAkStreamMgr.h).
  • WG-8656: Added error code to the prototype of LocalOutputFunc. LocalOutputFunc is the handler for local ouput. (AkMonitorError.h).
  • WG-12103: Added method PrepareBank() on the main API. (Preparing Banks).
  • WG-10441: Added argument to AK::MotionEngine::AddPlayerMotionDevice() to support DirectInput-compatible controllers.
  • WG-11949: Exposed object GUIDs in the SoundFrame.

New Features

  • WG-13541: New Wwise effect plug-in: SoundSeed Impact.
  • WG-12103: New bank loading scheme: PrepareBank(). The events/data structures and media of a single soundbank may be loaded separately using this method. (Preparing Banks).
  • WG-6970: Reworked the Low-Level I/O API, specific to the default implementation of the Stream Manager. It is now cross-platform, and some heuristics are passed down to the Low-Level I/O system. Coupled with asynchronous low-level I/O handshaking, it allows for tighter integration with the game regarding I/O. (Low-Level I/O). The default Stream Manager was reimplemented accordingly.
  • WG-6885: Streaming: AK_DEFERRED_LINED_UP streaming device now posts many concurrent requests to the Low-Level I/O. (AkStreamMgrModule.h and Low-Level I/O).
  • WG-8656: Streaming: Possibility to defer file opening in the Low-Level I/O so that it is executed in the I/O thread. (Low-Level I/O)
  • WG-12409: Streaming: New Low-Level I/O implementations for the new Low-Level I/O API. Cleaner, better organization. (Default Low-Level I/O Implementation)
  • WG-10996: New Low-Level I/O sample prototype for streaming from the video RAM on the PS3.
  • WG-13062: File Packager utility may now generate separate package files for soundbanks and streamed sounds. The File Package Low-Level I/O can now load more than one file package at a time.
  • WG-10441: Motion: Rumble now works with DirectInput-compatible controllers.

Behavior and Performance Changes

  • WG-6885: Streaming optimization: Re-organized and improved default Stream Manager implementation. Most importantly, memory management was improved.
  • WG-6885: Streaming behavior: AK_DEFERRED_LINED_UP streaming device now posts many concurrent requests to the Low-Level I/O.
  • WG-6764: Streaming optimization: Loop prefetching, computations for tasks deadline and buffering strategy were improved.
  • WG-11943: Memory usage optimization: Structural information concerning states in all AudioNodes now use dynamic allocation, saving ~7% total default memory pool size.
  • WG-11954: Memory usage optimization: Multiple memory saver alignments, saving significant memory in the sound engine.
  • WG-12162: CPU optimization: Increase number of buckets for lists of CAkIndexable.
  • WG-12262: Vorbis optimization: share decoded codebooks at run-time.
  • WG-11705: Lower engine voice management optimization: Streaming sounds that just started but did not read from disk yet are stopped as soon as a Stop event occurs, instead of waiting for the header to be parsed.

Bug Fixes and Miscellaneous Changes

  • WG-8879: Installer now adds shortcut to some soundframe samples.
  • WG-13186: Fixed: PS3: Volume RTPC on output bus doesn't affect center channel.

  • WG-13039: Fixed: Crash in CAkRanSeqCntr::ResetSpecificInfo() when using Game Object scope on a Random or Sequence Container.

  • WG-12343: Fixed: Switch container in step mode doesn't use global value when driven by an RTPC through a game parameter.
  • WG-12308: Fixed: Advanced profiler (Streaming tab) not working properly when 2 or more streaming devices are instantiated.
  • WG-12304: Fixed: Crash in CAkPath::NextVertex in very specific conditions.
  • WG-12249: Fixed: Wii: CRASH: OSLockMutex called in DSP voice kicking interrupt handler.
  • WG-12146: Fixed: Some streamed sounds fail to load with PrepareEvent().
  • WG-12224: Fixed: Low memory: AKASSERT(io_pContainerInfo != NULL); should be removed and the error should be correctly handled.
  • WG-12222: Fixed: Low memory: Initialisation error on monitoring is not handled properly.
  • WG-12211: Fixed: Low memory: Wrong size being read without error when loading busses.
  • WG-11760: Fixed: Low memory: Crash when decoding XMA, and when initializing the sound engine.
  • WG-12058: Fixed: Low memory: LoadBank() may fail silently.
  • WG-12875: Fixed: Wii: remote speaker whines for a while if the remote is activated in game.
  • WG-11081: Fixed: RTPC curves on effects are pushed to the sound engine while connected and a node is put into the Transport, even if the effects are disabled because "override parent" is not checked in the Effects tab.
  • WG-13400: Fixed: Streamed files used multiple times are copied multiple times (Copy Streamed Files).
  • WG-12201: Fixed: CRASH when updating a project (through perforce) while soundbanks are being generated.
  • WG-12277: Fixed: Assertion failure (AkMemoryMgrBase.cpp) when connecting to game with empty user-defined positioning.

  • WG-12226: ASSERT: (m_ulSizeLeft ==0) when playing streamed vorbis file with 4k granularity.
  • WG-12197: Fixed: Playback Position returned for streaming files is wrong after loop end.
  • WG-12183: Fixed: Streaming Profiler does not work properly with 2 devices.
  • WG-11704: Fixed: Music transition scheduled from the next segment instead of at next Beat/Bar/Grid/Cue when there is a transition segment and the pre-entry of the destination context is greater than the length of that transition segment.
  • WG-13479: Fixed: Ill-behaved fade-in offset in interactive music Playlist transitions.
  • WG-13479: Fixed: Ill-behaved fade-out offset in interactive music Playlist transitions when fade offset equals fade out duration.
  • WG-13114: Fixed: When changing state while interactive music is playing and the segment that is currently playing is the last one of a playlist (or if a single segment is playing), state change in actor-mixer is delayed to the end of the segment.
  • WG-12374: Fixed: Bug in sample-accurate stopping. May cause glitches while playing back interactive music. Platforms: PC, Xbox360, PS3.
  • WG-8218: Fixed: Glitch at the end of a music segment when it is paused without a fade out, then resumed. The first few frames of the audio clips may be played back again.
  • WG-12205: Fixed: Inoffensive assert in CAkPendingSwitchTransition::AttachPlayCmd() (in_iRelativeTime >= -SwitchSyncTime()) while switching interactive music, possible in some scenarios involving many levels of switch containers. The fix results in an optimization of transition scheduling.
  • WG-13501: Fixed: Wii: Streamed sources not sample-accurate when pitch != 0 or SR != 32 KHz (applies to random-sequence containers only, not music).
  • WG-10924: Motion: Vibration of Motion FX shouldn't be influenced by Master Audio Bus volume.

  • WG-12146: Fixed: Some streamed sounds fail to load with PrepareEvent().
  • WG-12134: Fixed: PS3: Codebook not being decoded properly when an in-memory Vorbis sound does not start at the beginning of the file. This can occur in some scenarios of virtual voices or interactive music. The sound silently fails to play, and random (but aligned) data is sent to the SPU.
  • WG-12056: Fixed: ASSERT (AkList2.h) when loading SoundBanks.
  • WG-12050: Fixed: Wii: Cannot pause vorbis on Wii.
