Audio / Capturing sound then play it

« on: May 05, 2017, 05:49:24 pm »

Hello,

i followed this tutorial https://www.sfml-dev.org/tutorials/2.4/audio-recording.php to capture a sample then play it, here is the code:

#include <iostream>
#include <string>
#include <chrono>
#include <SFML/Audio.hpp>
#include <SFML/Audio/SoundBuffer.hpp>
#include <SFML/Audio/SoundBufferRecorder.hpp>
#include <SFML/Audio/Sound.hpp>


unsigned long int a=1,b=0;


int main(){

if (!sf::SoundBufferRecorder::isAvailable()){std::cout<<"ERROR NO DEVICE FOUND";}

sf::SoundBufferRecorder recorder;


recorder.start();

while(a){

        ++b;

        if(b>2000000000){

                --a;}}

recorder.stop();


const sf::SoundBuffer& buffer = recorder.getBuffer();

std::cout<<"PROGRAM SUCCESSFUL"<<std::endl;

sf::Sound sound;

sound.setBuffer(buffer);

sound.play();

return 0;}

It is supposed recording a sample then play it but all what i get is PROGRAM SUCCESSFUL after time of the loop, i followed exactly all that tuto and have required devices (microphone and speakers), could someone help me to correct my mistakes ?
