Want process audio in chunks, how can make?
Thanks you

This is a little beyond the scope of this library, but if you look at the loadAudioFileAndProcessSamples() example in examples.cpp, then you could replace part 3 with...

        float gain = 0.5f;
        constexpr int frameSize = 512;


        for (int i = 0; i < (a.getNumSamplesPerChannel() - frameSize); i += frameSize)
        {
            for (int channel = 0; channel < a.getNumChannels(); channel++)
            {
                float frame[frameSize];
                
                // copy samples into frame
                for (int k = 0; k < frameSize; k++)
                    frame[k] = a.samples[channel][i + k];
            
                // !
                // do something with the frame here
                // !
                
                // copy samples back to audio file buffer
                for (int k = 0; k < frameSize; k++)
                    a.samples[channel][i + k] = frame[k];
                
                a.samples[channel][i] = a.samples[channel][i];
            }
        }

Hope that helps!

Note also that the above code will process left and right channels for stereo files so you'll need to handle that yourself by looking at the channel variable and acting accordingly (depending on your needs).
