in this study is a multimedia music project which focuses on sound visualization. The purpose of this study is to provide audiences with diverse creative art experience through visual and auditory multimedia by orchestrating sound created between instruments and computer and furthermore by showing realtime visual response caused by sound. Visual construction was possible through processing and Arena5 while orchestrating sound and sound response visualization was done by max/MSP. Max/MSP was further utilized to control the automation of sound and visual processing values for the formation of a project as a whole. automation allowed for greater efficiency in controlling audio-visual contents and also reduced operator's responsibility during performance. Therefore, automation of audio-visual variables indicates possible construction of an effective single-person system. However, reducing technical complication which may arise from compatibility difficulties between instruments and computer systems remains as an assignment during performances. Project did not encounter any major technical complications given the simple I/O(Input/Output) connections. The reason being that only a single pair of microphones were used to receive and process stereo sound signals to speakers and visual/video data to a large screen. Unfortunately, although aforementioned system reduces the frequency of errors, it lacked diversification during a performance. Nevertheless, we envision a wholly unconventional performance through utilization of diverse data sets, such as volume, to express and communicate the creator's message to the art world. As various data sets are used, hardware connection may become complex and lead to instability in the computer system. Therefore, revision and improvement in an unstable computer system, in order to produce a communicative work with the audience, is an important aspect of the future study.
