Android-Specific AkPlatformInitSettings
This page contains information about the Android-specific initialization settings.
| AkThreadProperties threadLEngine | Lower engine threading properties. |
| AkThreadProperties threadOutputMgr | Ouput thread threading properties. |
| AkThreadProperties threadBankManager | Bank manager threading properties (its default priority is AK_THREAD_PRIORITY_NORMAL). |
| AkThreadProperties threadMonitor | Monitor threading properties (its default priority is AK_THREAD_PRIORITY_ABOVENORMAL). This parameter is not used in Release build. |
| AkAudioAPI eAudioAPI | Main audio API to use. Leave to AkAPI_Default for the default sink (default value). AkAudioAPI |
| AkUInt32 uSampleRate | Sampling Rate. Set to 0 to get the native sample rate. Default value is 0. |
| AkUInt16 uNumRefillsInVoice | Number of refill buffers in voice buffer. Defaults to 4. |
| bool bRoundFrameSizeToHWSize | Used when hardware-preferred frame size and user-preferred frame size (AkInitSettings.uNumSamplesPerFrame) are not compatible. If true (default) the sound engine will initialize to a multiple of the HW setting, close to the user setting. If false, the user setting is used as is, regardless of the HW preference (might incur a performance hit). |
| SLObjectItf pSLEngine | OpenSL engine reference for sharing between various audio components. |
| JavaVM* pJavaVM | Active JavaVM for the app, used for internal system calls. Usually provided through the android_app structure given at startup or the NativeActivity. This parameter needs to be set to allow the sound engine initialization. |
| jobject jActivity | android.app.Activity instance for this application. Usually provided through the android_app structure, or through other means if your application has an overridden activity. |
| bool bVerboseSink | Enable this to inspect sink behavior. Useful for debugging non-standard Android devices. |
| bool bEnableLowLatency | Used the lowest output latency possible for the current hardware. If true (default), the output audio device will be initialized in low-latency operation, allowing for more responsive audio playback on most devices. However, when operating in low-latency mode, some devices may have differences in audio reproduction. If false, the output audio device will be initialized without low-latency operation. |
Android-Specific Audio Output API
Use with AkPlatformInitSettings to select the API used for audio output. Use AkAudioAPI_Default, it will select the more appropriate API depending on the computer's capabilities. Other values should be used for testing purposes.
| enum AkAudioAPI | |
|---|---|
| AkAudioAPI_AAudio | Use AAudio (lower latency, available only for Android 8.1 or above). |
| AkAudioAPI_OpenSL_ES | Use OpenSL ES (older API, compatible with all Android devices). |
| AkAudioAPI_Default | Default value, will select the more appropriate API (AAudio for compatible devices, OpenSL for others). |
