Tae Hong Park is a composer, bassist, and music technologist. He received his Bachelor of Engineering degree in Electronics from Korea University in 1994 and has worked in the area of digital communication systems and digital musical keyboards at the LG Central Research Laboratory in Seoul, Korea from 1994 to 1998. He also holds degrees from Dartmouth College (M.A. in Electro-Acoustic Music) and Princeton University (M.F.A and Ph.D. in composition). His current interests are primarily in composition of electro-acoustic and acoustic music, technical research in multi-dimensional aspects of timbre, pattern recognition, signal processing, automatic musical instrument classification, and computer-aided music analysis. His project, Citygram is a large-scale project that began in 2011. Citygram aims to deliver a real-time visualization/mapping system focusing on non-ocular energies through scale-accurate, non-intrusive, and data-driven interactive digital maps. The first iteration, Citygram One, focuses on exploring spatio-acoustic energies to reveal meaningful information including spatial loudness, traffic patterns, noise pollution, and emotion/mood through audio signal processing and machine learning techniques.
