Latest Patents

Hunseok Seo's latest patents include a "Pitch determination method and apparatus using spectral analysis." This invention provides a method and apparatus for detecting pitch through frequency analysis. It analyzes an externally input digital signal into frequency component values at predetermined time intervals. The positions of peaks in the digital signal are detected based on these frequency component values. The invention determines whether a frequency at the maximum peak position is a pitch or a harmonic frequency of the pitch, thereby minimizing the error range in pitch detection.

Another significant patent is the "2-phase pitch detection method and apparatus." This method analyzes an externally input digital signal into frequency components and detects a pitch candidate based on these components. It compares the error range for the pitch candidate with a calculated error range. The method performs autocorrelation on the digital signal within a predetermined time range when the error range for the result of autocorrelation is acceptable. Ultimately, it determines a pitch within the intersection of frequency ranges obtained through frequency analysis and autocorrelation.
