In the start of the flow chart, there are two steps, which are prepared for new input samples. Firstly, all the samples in the buffer (512 samples) are down shifted and then put new 32 samples at the end of the buffer, which is required for further calculations. But in this work different algorithm, which contain both in only one step is used. One more variable known as ofs is present, which shows where is the end of the previous data read, because 32 samples into 512 samples buffer is read, it is different number every time.
