403 If this is FrequencyDomain, the host will carry out a windowed FFT of size equal to the negotiated block size on the data before passing the frequency bin data in to <a class="el" href="classPercussionOnsetDetector.html#dfd989812b3e0cb8f4b498f56a5a9614" title="Process a single block of input data.">process()</a>.

The plugin does not get to choose the window type -- the host will either let the user do so, or will use a Hanning window.

585 A plugin may return 0 if it has no particular interest in the step size. In this case, the host should make the step size equal to the block size if the plugin is accepting input in the time domain.

765 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 in this case will be the real time in seconds of the start of the supplied block of samples.<p>

766 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>
