Sample Description

You can control orientation of sound by using panning 3D features.
Panning 3D supports interior panning and you can orient the sound image inside the speakers.
For more information on its features, see Panning .

Use the following functions to control orientation from program.

• criAtomExPlayer_SetPan3dAngle
  • Set panning 3D angle.
• criAtomExPlayer_SetPan3dInteriorDistance
  • Set panning 3D distance.
• criAtomExPlayer_SetPan3dVolume Set panning 3D volume.

The following is a code to do panning.

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);
    }
