Audio / SFML 2 sf::SoundRecorder

« on: December 22, 2011, 11:06:23 pm »

Hello, this code:

Code: [Select]


class Recorder : public sf::SoundRecorder
{

    virtual bool OnProcessSamples(const sf::Int16* Samples, std::size_t SamplesCount)
    {
        cout << *(Samples+1000) << "\n";
        return true;
    }

};


Outputs me (from console) this kind of numbers:

Code: [Select]


0
-6

-8

no matter what, if audio is playing or not, numbers are same.

I have X-FI, and I use "What u hear" as a recording input.

Now, what I want to know, does SFML always records from default audio device, and always records from microphone?

Hint, I want to make realtime audio visualizator.
