Sample description

By using the Panning 3D function, you can control the positioning of the sound.
Panning 3D supports interior panning, and you can position the sound image inside the speaker.
For details on the function, see Panning.

Functions for controlling positioning

• criAtomExPlayer_SetPan3dAngle : Specifies the panning 3D angle.
• criAtomExPlayer_SetPan3dInteriorDistance : Specifies the panning 3D distance.
• criAtomExPlayer_SetPan3dVolume : Specifies the panning 3D volume.

CriAtomExPlayerHn player;
CriFloat32 pan3d_angle;
 
    /* Create a player */
    player = criAtomExPlayer_Create(NULL, NULL, 0);
    /* Set a Cue */
    criAtomExPlayer_SetCueName(player, acb_hn, "heli_Loop");
    /* Start playback */
    criAtomExPlayer_Start(player);
 
    /* Play back while changing panning 3D angle */
    for(pan3d_angle = -180.0f; pan3d_angle <= 180.0f; pan3d_angle += 0.1f) {
        /* Wait for V synchronization */
        criFwSys_WaitVsync();
        /* Execute the server process */
        criAtomEx_ExecuteMain();
        /* Set the panning 3D angle */
        criAtomExPlayer_SetPan3dAngle(player, pan3d_angle);
        /* Update */
        criAtomExPlayer_UpdateAll(player);
    }
