This document summarizes an artificial intelligence algorithm for analyzing and improving the quality of speech and sound signals. The algorithm can extract speech or sound signals from recordings and analyze characteristics like pitch, volume, and stereo. It uses techniques like autocorrelation, histogram spread, and cumulative sum to denoise signals and improve quality. The algorithm is useful for applications like security, forensic detection, and assessing job candidates' voices. It works by sampling input signals, applying a fast Fourier transform to convert to the frequency domain, and using a short-term Fourier transform with averaging to analyze short sections of the signal. Autocorrelation helps determine the fundamental pitch by finding the highest correlation between the original and delayed signals. The algorithm outputs various plots and
