Audio Library (AX) API

Introduction

Wii audio library (AX) provides an environment for manipulating the audio subsystem.

AX System Initialization

To use the AX library, follow the procedure below.

• Call the AXInit function to initialize AX.
• Call the AXSetMode function to run AX in stereo, surround, or Dolby Pro Logic® II mode. Default mode is stereo.
• Call the AXSetCompressor function to switch the output compressor on or off. Default is on.
• Call the AXRegisterCallback function to register the application that sets the service routine for each audio frame.
• Call the AXQuit function to shut down AX.

Examples

The following is a simplified sample code for using the AX library.

#include <revolution.h>

void audioFrameCallback(void)
{
// run frame based audio apps here (mixer, sequencer, synth... etc.)
}

void main(void)
{
    ...       // other initializations

    AXInit();
    AXRegisterCallback(&audioFrameCallback);

    while(1)
    {   
    ...   // game loop
    }

    AXQuit();   

    ...        // other shutdown
}
