Accessing the buffer

[PJ]

Hi guys, im quite new to SFML. I'm trying to access the samples but when i apply the sound.getSamples() function all i obtain is an Int16 value.I was expecting an array of integer values to apply FFT later on. Any tip or help?

And what should i use to get a real-time array? Sound or Music?

What is the class of "sound"? Don't forget to loook at the documentation and tutoriels, classes and functions are all well described.

You want to get real-time samples from what source?

#include <iostream>
#include <SFML/Audio.hpp>
#include <SFML/Graphics.hpp>
#include <fftw3.h>
#include <Windows.h>


int main()
{
        // Create the main window
        sf::RenderWindow window(sf::VideoMode(800, 600), "OUR TEST");
        sf::SoundBuffer buffer;
        sf::Sound sound;
        if (!buffer.loadFromFile("Etherwood - Spoken.wav"))
        {
                std::cout << "ERROR"<<std::endl;
        }
        sound.setBuffer(buffer);
        sound.setVolume(25);

        std::cout << "Sample Rate: " << buffer.getSampleRate() << std::endl;

        while (window.isOpen())
        {
                // Process events
                sf::Event event;
                while (window.pollEvent(event))
                {
                        /*while (sound.getStatus() == sf::Sound::Playing) {
                                std::cout << buffer.getSamples() << std::endl;
                                Sleep(400);
                        }*/
                        switch (event.type)
                        {
                        case sf::Event::Closed:
                                window.close();
                                break;
                        case sf::Event::KeyPressed:
                                if (event.key.code == sf::Keyboard:: P)
                                {
                                        sound.play();
                                }
                                if (event.key.code == sf::Keyboard::Escape)
                                        window.close();
                                break;
                        }
                }
                window.clear();
                window.display();
        }
        return EXIT_SUCCESS;
}

This is my entire code. I run the getSamples() on the buffer.
I want to get a real time array from my buffer that is streaming the audio

[Laurent]

SoundBuffer::getSamples() returns a pointer to the array of samples.

Then, to know which samples are being played, you have to perform a lookup into this array based on the current playing position of the Sound (you'll have to multiply the time position by the sample rate and channel count to get the sample index).

As I said, everything's described in the documentation, take the time to read it.

Ok, thanks for the reply, i'll find out
