AkInitSettings Struct Reference

#include <AkSoundEngine.h>

Public Attributes

AkAssertHook  pfnAssertHook
  External assertion handling function (optional) More...
 
AkUInt32  uMaxNumPaths
  Maximum number of paths for positioning. More...
 
AkUInt32  uCommandQueueSize
  Size of the command queue, in bytes. More...
 
bool  bEnableGameSyncPreparation
  Sets to true to enable AK::SoundEngine::PrepareGameSync usage. More...
 
AkUInt32  uContinuousPlaybackLookAhead
  Default is 1 audio quantum, also known as an audio frame. Its size is equal to AkInitSettings::uNumSamplesPerFrame / AkPlatformInitSettings::uSampleRate. For many platforms the default values - which can be overridden - are respectively 1,024 samples and 48 kHz. This gives a default 21.3 ms for an audio quantum, which is adequate if you have a RAM-based streaming device that completes transfers within 20 ms. With 1 look-ahead quantum, voices spawned by continuous containers are more likely to be ready when they are required to play, thereby improving the overall precision of sound scheduling. If your device completes transfers in 30 ms instead, you might consider increasing this value to 2 because it will grant new voices 2 audio quanta (~43 ms) to fetch data. More...
 
AkUInt32  uNumSamplesPerFrame
  Number of samples per audio frame (256, 512, 1024, or 2048). More...
 
AkUInt32  uMonitorQueuePoolSize
  Size of the monitoring queue, in bytes. This parameter is not used in Release build. More...
 
AkOutputSettings  settingsMainOutput
  Main output device settings. More...
 
AkUInt32  uMaxHardwareTimeoutMs
  Amount of time to wait for HW devices to trigger an audio interrupt. If there is no interrupt after that time, the sound engine will revert to silent mode and continue operating until the HW finally comes back. Default value: 2000 (2 seconds) More...
 
bool  bUseSoundBankMgrThread
  Use a separate thread for loading sound banks. Allows asynchronous operations. More...
 
bool  bUseLEngineThread
  Use a separate thread for processing audio. If set to false, audio processing will occur in RenderAudio(). Custom Scheduling of Audio Rendering. More...
 
AkBackgroundMusicChangeCallbackFunc  BGMCallback
  Application-defined audio source change event callback function. More...
 
void *  BGMCallbackCookie
  Application-defined user data for the audio source change event callback function. More...
 
AkOSChar szPluginDLLPath
  When using DLLs for plugins, specify their path. Leave NULL if DLLs are in the same folder as the game executable. More...
 
AkFloorPlane  eFloorPlane
  Floor plane axis for 3D game object viewing. More...
 
AkReal32  fGameUnitsToMeters
 
AkTaskSchedulerDesc  taskSchedulerDesc
  The defined client task scheduler that AkSoundEngine will use to schedule internal tasks.
More...
 
AkUInt32  uBankReadBufferSize
  The number of bytes read by the BankReader when new data needs to be loaded from disk during serialization. Increasing this trades memory usage for larger, but fewer, file-read events during bank loading. More...
 
AkReal32  fDebugOutOfRangeLimit
  Debug setting: Only used when bDebugOutOfRangeCheckEnabled is true. This defines the maximum values samples can have. Normal audio must be contained within +1/-1. This limit should be set higher to allow temporary or short excursions out of range. Default is 16. More...
 
bool  bDebugOutOfRangeCheckEnabled
  Debug setting: Enable checks for out-of-range (and NAN) floats in the processing code. This incurs a small performance hit, but can be enabled in most scenarios. Will print error messages in the log if invalid values are found at various point in the pipeline. Contact AK Support with the new error messages for more information. More...
