Time-Domain Pitch Determination
Time-domain pitch determination is the oldest means of automatic pitch measurement. Figure 6.1 shows the block diagram of a typical time-domain PDA with the three “classical” blocks preprocessor, basic extractor, and postprocessor, as described by McKinney (1965). The main property of the basic extractor is the ability to process every pitch period individually. This is an advantage in accuracy since the PDA can handle rapid changes in F0 or even slightly irregular signals; it is a disadvantage on the other hand since the PDA may have difficulties when individual periods are disturbed by noise or spurious signals.
