◆ SetSpeakerAngles()
Sets speaker angles of the specified device. Speaker angles are used for 3D positioning of sounds over standard configurations. Note that the current version of Wwise only supports positioning on the plane. The speaker angles are expressed as an array of loudspeaker pairs, in degrees, relative to azimuth ]0,180]. Supported loudspeaker setups are always symmetric; the center speaker is always in the middle and thus not specified by angles. Angles must be set in ascending order. Typical usage:
- Initialize the sound engine and/or add secondary output(s).
- Get number of speaker angles and their value into an array using GetSpeakerAngles().
- Modify the angles and call SetSpeakerAngles(). This function posts a message to the audio thread through the command queue, so it is thread safe. However the result may not be immediately read with GetSpeakerAngles().
- 警告
- This function only applies to configurations (or subset of these configurations) that are standard and whose speakers are on the plane (2D).
- 戻り値
- AK_Success if successful.

GetSpeakerAngles()
- 引数
-
| in_pfSpeakerAngles |
Array of loudspeaker pair angles, in degrees relative to azimuth [0,180]. |
| in_uNumAngles |
Number of elements in in_pfSpeakerAngles. It must correspond to AK::GetNumberOfAnglesForConfig( AK_SPEAKER_SETUP_DEFAULT_PLANE ) (the value returned by GetSpeakerAngles()). |
| in_fHeightAngle |
Elevation of the height layer, in degrees relative to the plane [-90,90]. |
| in_idOutput |
Output ID to set the bus on. As returned from AddOutput or GetOutputID. You can pass 0 for the main (default) output |
