{wiki=Pitch_detection_algorithm}
Pitch detection algorithms are techniques used to identify the pitch or fundamental frequency of a sound signal, particularly in musical contexts or speech analysis. The pitch is the perceived frequency of a sound, which allows us to distinguish between different musical notes or spoken words. There are several common pitch detection algorithms, each with varying degrees of complexity and accuracy: 1. **Zero-Crossing Rate**: This method counts how many times a signal crosses the zero-axis within a specific time window.
