With a total of two patents to his name, Lim's work focuses on enhancing audio experiences through innovative methods and apparatus.

Latest Patents

Jun-Seok Lim's latest patents include a "Sound field reproduction apparatus and method for reproducing reflections." This invention provides a sound field reproducing apparatus that includes an input unit for receiving reflection reproducing information. It also features a signal processor that selects loudspeakers and calculates reflection signals based on the reflection reproducing information. Additionally, a signal treatment unit localizes the calculated reflection signal on a virtual sound image according to a panning algorithm, while a reproducer reproduces the localized reflection signals through the selected loudspeakers.

Another significant patent is the "Apparatus and method for reproducing surround wave field using wave field synthesis." This invention includes an audio signal analyzer that analyzes a received multi-channel audio signal to check the number of audio signal channels. It extracts a sound source signal for each checked channel and utilizes a wave field synthesis renderer to localize the extracted sound source signal at a virtual sound image outside a narrow space. An audio reproducer then reproduces the localized virtual sound source signal.
