Trivial example of loading and playback of audio file in WAV format using OpenAL library and ALUT.

openal_wav_load.cpp

#include <iostream>
#include <stdlib.h>
#include <alut.h>

const unsigned NUM_BUFFERS = 1;
const unsigned NUM_SOURCES = 1;

int main(int argc, char* argv[])
{ 
    /* Sound buffer variable */
    ALuint buffer = 0;
  
    /* Sound source varialbe */
    ALuint source = 0;
  
    /* Initialize ALUT */
    alutInit(&argc, argv);
  
    /* Generate sound buffer */
    alGenBuffers(NUM_BUFFERS, &buffer);
  
    /* Load WAV file */
    buffer = alutCreateBufferFromFile("sound.wav");
  
    /* Generate sound source (sound position in 3D space) */
    alGenSources(NUM_SOURCES, &source);
  
    /* Associate source with sound buffer */
    alSourcei(source, AL_BUFFER, buffer);
  
    /* Play the sound */

    /* Wait for playing sound */
    alutSleep(1);
  
    /* Exit from ALUT */
