Audio / Re: New audio file 2 time longer than original.

« on: March 03, 2016, 04:41:55 pm »

I downloaded Audacity and converted an mp3 file to wav. I tested it and the bug is still there.

I am passing a c string because of the purposes of my program.

I used an online YT to wav converter to get a wav file.

I think that SFML still has a bug. I tried this two lines of code:

buffer.loadFromFile(path.c_str());
buffer.saveToFile("test.wav");
 

And test.wav still is still produced like before. (the duration is 2 times longer).
I guess I leave it like this. If someone knows what could be the issue please let me know.

EDIT: if someone has a link to download a free .wav file plase let me know. But I believe that the file is not the issue here.

I was not sure before but now when you asked I downloaded latest version once again and the file is still not correct.

My sound file is 5:07 mins long.

By 2 times longer I mean that when I play it, it plays normal for 5:07 mins and then from 5:08 to 10:14 is just pure silence.

I'm not really sure what do you mean by : "Do you get this effect with all samples or just one?"

Basically I want to get all the samples, change them a little bit and then make a new file.

My code is identical to the code that I posted. Those calculations that I am making in my program (changing the samples) are not included on purpose, for simplicity sake.

I checked if the sound has 2 channels and it does. When I play the original file everything works fine.

                cout << "Enter the name of the audio\n>";
                                cin >> path;

                                sf::SoundBuffer buffer;
                                buffer.loadFromFile(path.c_str());

                                sf::Int16 * samples = new sf::Int16[buffer.getSampleCount()];

                                int ind = 0, progress = 0, last = 0;
                                float running = 1.0f;
                                string bin_code = "";

                                for (int i = 0; i < buffer.getSampleCount(); i++)
                                {
                                        samples[i] = buffer.getSamples()[i];
                                }
                                sf::SoundBuffer buff;

                                buff.loadFromSamples(samples, buffer.getSampleCount(), buffer.getChannelCount(), buffer.getSampleRate());
                                buff.saveToFile("test.wav");

                                delete[] samples;

 

The file that is created is two times longer then original. Its not bigger (in size) but it has duration 2 times longer than original. Also, when i try to play it with SFML it doest play but when I try to play it with Windows media player it does play (when it exceeds the duration of the song the music is still "playing" but there's no sound).

Graphics / Re: getting pixels from sf::Image

« on: February 10, 2016, 03:08:15 pm »

I was using .bmp format. I checked if it supports transparency and Google says it does.


EDIT: well.. I ended up checking all the types of images that SFML supports and the format that works is indeed .png.

Still not sure why the others arent working, guess Google is a liar or SFML has some buggs.

Graphics / getting pixels from sf::Image

« on: February 10, 2016, 12:28:16 am »

I am currently trying to change the values of pixels of an Image.

When I change r g b values of an image and then I save it to a file it works propery.

Then I tried to change the alpha value also (I assing 253 or 245) and save the image. And my program does save it.

And then one weird thing happens when I open that changed image. The r g and b values are changed the way I changed them before, but alpha is ALWAYS 255 and I am wondering why if I saved the image.

As you might know, I am using setPixel function to change the pixels.
