Title: Nam-In Park: Innovator in Audio Signal Processing
Introduction
Nam-In Park is a notable inventor based in Gwangju, South Korea. He has made significant contributions to the field of audio signal processing, holding a total of 2 patents. His work focuses on enhancing speech signals and reducing noise in audio encoding.
Latest Patents
One of his latest patents is titled "Packet loss concealment for bandwidth extension of speech signals." This invention discloses a speech receiving apparatus that includes a low-band PLC module and a synthesis filter. These components work together to reconstruct a low-band speech signal from a previous good frame. Additionally, a high-band PLC module reconstructs the high-band speech signal of the lost frame. The invention also features a transforming part that transforms the low-band speech signal into a frequency range, and a bandwidth extending part that generates extended MDCT coefficients for the high-band speech signal. A smoothing part and an inverse transforming part further refine the output, resulting in a wideband speech signal.
Another significant patent by Nam-In Park is the "Method and apparatus for audio encoding for noise reduction." This method involves receiving an audio signal and performing modified discrete cosine transformation (MDCT) to convert the audio signal into either a long block or a short block. The process includes reducing noise in the audio signal and performing advanced audio coding (AAC) on the modified signal.
Career Highlights
Nam-In Park has worked with prestigious organizations such as the Gwangju Institute of Science and Technology and Samsung Electronics Co., Ltd. His experience in these institutions has allowed him to develop innovative solutions in audio technology.
