The ring-buffer based incremental processing is illustrated in Figure 3. Three levels are present in this setup: wave, frames, and pitch. A cWaveSource component writes samples to the’wave’ level. The write positions in the levels are indicated by a red arrow. A cFramer produces frames of size 3 from the wave samples (non-overlapping), and writes these frames to the ‘frames’ level. A cPitch (a component with this name does not exist, it has been chosen here only for illustration purposes) component extracts pitch features from the frames and writes them to the ‘pitch’ level. In figure 3 (right) the buffers have been filled, and the write pointers have been warped. Data that lies more than ‘buffersize’ frames in the past has been overwritten.
