606 Process a single block of input data.
607 <p>
608 If the plugin's inputDomain is TimeDomain, inputBuffers will point to one array of floats per input channel, and each of these arrays will contain blockSize consecutive audio samples (the host will zero-pad as necessary). The timestamp will be the real time in seconds of the start of the supplied block of samples.<p>
609 If the plugin's inputDomain is FrequencyDomain, inputBuffers will point to one array of floats per input channel, and each of these arrays will contain blockSize/2+1 consecutive pairs of real and imaginary component floats corresponding to bins 0..(blockSize/2) of the FFT output. That is, bin 0 (the first pair of floats) contains the DC output, up to bin blockSize/2 which contains the Nyquist-frequency output. There will therefore be blockSize+2 floats per channel in total. The timestamp will be the real time in seconds of the centre of the FFT input window (i.e. the very first block passed to process might contain the FFT of half a block of zero samples and the first half-block of the actual data, with a timestamp of zero).<p>
610 Return any features that have become available after this process call. (These do not necessarily have to fall within the process block, except for OneSamplePerStep outputs.)
