Title: Doill Jung: Innovator in Pitch Detection and MIDI Music Reproduction

Introduction

Doill Jung is a prominent inventor based in Seoul, South Korea. He has made significant contributions to the fields of pitch detection and MIDI music reproduction. With a total of 7 patents to his name, Jung continues to push the boundaries of technology in music and sound analysis.

Latest Patents

One of Jung's latest patents is a "Pitch determination method and apparatus using spectral analysis." This invention provides a method and apparatus for detecting pitch through frequency analysis. The process involves analyzing an externally input digital signal into frequency component values at predetermined time intervals. By detecting the positions of peaks in the digital signal based on these values, the system determines whether a frequency at a maximum peak position is a pitch or a harmonic frequency of the pitch. This innovation minimizes the error range in pitch detection, allowing for more accurate results.

Another notable patent is the "Method and apparatus for reproducing MIDI music based on synchronization information." This invention allows for the reproduction of MIDI music by detecting MIDI performance information from a musical score or MIDI data. It generates synchronization information that contains real performance onset time data for each note. By matching this information with the MIDI performance data, the system enables musical trainees to reproduce and listen to performances without needing the actual sound played by a desired musician.
