Audio / Re: Applying echo effect using sfml audio

« on: February 17, 2014, 11:14:54 pm »

Haha  , I didn't forget the buffer of course but there was a mess in declarations of those three objects.

In my real situation I'm actually using a class to wrap up the working with sound functionality which is used by other objects and I made some scope errors  , This code is just a demo (an awful one  ), maybe I'm looking like a totally rookie programmers but it's the "deadlines pressure" which make the impossible possible .

Thank you about the sf:Clock clue that is how it's done but as the doc said about sleep:
 

Make the current thread sleep for a given duration.

I don't mind if the echo sound thread blocked less than a second.

i'm sorry for annoying everybody my mistake was really dump  , I declared the new Sound object in the wrong scope, and now it is working fine and this how I make it:

#include <SFML/Audio.hpp>
void Echo();
//That what I missed
sf::SoundBuffer buffer;
sf::Sound sound;
sf::Sound echo;

int main ()
{
    buffer.loadFromFile("simple.wav");
    sound.setBuffer(buffer);
    echo.setBuffer(buffer);
    sound.play();
    sf::sleep(sf::seconds(8)); //just for start the echo after 8 sec
    Echo();
    while(sound.Playing);
    return 0;
}

void Echo(){
    echo.setPlayingOffset(sound.getPlayingOffset());
    sf::sleep(sf::seconds(0.2f));
    echo.play();
}

Audio / Applying echo effect using sfml audio

« on: February 17, 2014, 01:47:53 am »

hi 

i'm pretty new with sfml but it was really simple to use, but now I'm having some problems with sfml-audio, I'm trying to apply echo effect on sound by replaying the same sf::SoundBuffer in another sf::Sound object with small latency but I still fail in every way i try.

is it possible to make an echo using sfml ?or there is another way ?

Thanks.
