Real-time Automatic Equalization for Reducing Spectral Masking in Problematic Frequency Bands between Vocal and Instrument Tracks Audio plug-in software development in C++ / JUCE / Faust The analyzer graphics shows 1) Frequency spectrum of each signal 2) Problematic frequency bands indicated red color 3) Automatic EQ curve (Gain constant) and (threshold) are user parameters. Gain reduction for each band uses a peak filter centered at fc and the Q factor of the corresponding bandwidth. 더보기

Cyberpunk Sanjo (산조) 2023: Designing expressive vibrato/pitch bend controller for a virtual Korean traditional instrument My solo-performance at SLOrktastic Chamber Music 2023, at CCRMA Stage, Stanford University. MIDI keyboards typically feature a pitch wheel that allows players to add vibrato or pitch bend effects to their virtual instruments. However, when it comes to expressing the rich, nuanced, and dynamic vibrato and pitch bend techniques ("구슬지다." in Korean) found in Korean traditional instruments, the pitch.. 더보기
PACT: perceptual audio codec We used block switching to improve performance on transients; M/S coding to reduce stereo redundancy; and Huffman coding to reduce redundancy in our bitstream.

Interactive Spatial Audio Performance: Controlling the spatial location of sound sources (3rd-order Ambisonics) in real time by head movement detection Demo video (Full Performance video is below) In this project, I designed an AI tool for interactive spatial audio performance (with an Ambisonics loudspeaker array) that enables performers to dynamically manipulate the spatial locations of sound sources in real time through their body movements, including head movement and hand gestures. This project demonstrates the possibility of controlling t.. 더보기
AI-based Real-Time Control of Electric Guitar Effects through Facial Expression and Gesture Detection Demo Video 𝘕𝘰𝘸 𝘺𝘰𝘶 𝘤𝘢𝘯 𝘤𝘰𝘯𝘵𝘳𝘰𝘭 𝘺𝘰𝘶𝘳 𝘨𝘶𝘪𝘵𝘢𝘳 𝘦𝘧𝘧𝘦𝘤𝘵𝘴 𝘸𝘪𝘵𝘩 𝘺𝘰𝘶𝘳 "𝘨𝘶𝘪𝘵𝘢𝘳 𝘧𝘢𝘤𝘦𝘴"!I discovered that facial expression and gesture detection can provide more expressive and intuitive (and fun) control for electric guitar effects. I believe this is because facial expressions and gestures have a stronger emotional connection to music performance than pr.. 더보기
Web audio based guitar recording, effects, synth, and drum sound design This is my original composition which is a piece of instrumental guitar music. I found the random pitch shift effect on an electric guitar using web audio coding makes an interesting ‘dreamy’ sound, which I had never heard from any other commercial guitar effect pedals. Inspired by this new sound, I wrote this composition. The guitar is recorded on a webpage using Web ChucK code. I did not use a.. 더보기
