Real Time audio processing (Input From Sound Card)

[linde]

I`m doing a C++ project that needs to acquire the data from soundcard..
I tried to use the SoundBufferRecorder but on my understanding upon reading the documentation The sound buffer is valid only after the capture has ended.

Is there a way to get the data on realtime?

Thanks in advance!

Yes that is correct sf::SoundBufferRecorder is not what you are looking for. If you want to do near real-time processing you need to derive from sf::SoundRecorder. Then you can implement the onProcessSamples() method, which will provide you with the samples at a specified rate. Take a look at the doc or the implementation of sf::SoundBufferRecorder. Also the VoIP example might show you a way how to do it.
