NASA(National Aeronautics and Space Administration) 지구에서 2 광년 떨어진 페르세우스(Perseus) 은하단에 위치한 블랙홀 소리를 검출하였다.[2022 8 24]
– Data Sonification, Black Hole at the Center of the Perseus Galaxy Cluster

블랙홀에서 배출하는 방대한 빛의 주파수 범위를 인간의 가청 주파수 범위로 변환한 광학 데이터를 사용하여 Real Time Interactive Music으로 만든 작품이다.

NASA (National Aeronautics and Space Administration) detected the sound of a black hole located in the Perseus galaxy cluster, 200 million light-years away from Earth. [August 24, 2022]
– Data Sonification, Black Hole at the Center of the Perseus Galaxy Cluster

This work was created as Real Time Interactive Music using optical data that converted the vast frequency range of light emitted from a black hole into the human audible frequency range.

[프로세싱]

1) Data Sonification 자료를 FFT(Fast Fourier Transform) 분석 검출하기 위해 Hanning Window 적용, 이는 결과의 Resolving, Leakage, Inter-Frequency Distortion 확인하고 불연속에서 발생될 있는 이슈를 확인하는 용도이다.
결과적으로는 Data Sonification 이용한 Formant 기법을 사용하여 Vowel 표현 하기 위함이다.

Max MSP filtergraph~ 이용하여 Formant 해당되는 주파수를 종합하여 실시간으로 Vowel Frequency 변하도록 하였다.

Granural Synthesis 이용한 Resynthesis Groove~ 오브젝트를 이용해 재합성된 모든 소리를 Effecting. – Frequency Modulation/ Additive Synthesis/ Reverb/ Flanger/ Tremolo

2) TouchDesigner, Feedback System 착안하여 음악에 실시간 반응하도록 하였다. 이는 잔상의 결과물로 Set Opacity 제곱근이다.

1) Hanning Window is applied to detect Data Sonification data after FFT (Fast Fourier Transform) analysis. This is used to check the resolving, leakage, and inter-frequency distortion of the results and to identify issues that may arise from discontinuity.
As a result, the purpose is to express Vowel using Formant technique using Data Sonification.
Using Max MSP’s filtergraph, the frequencies corresponding to the formant were synthesized to change the Vowel Frequency in real time.

Resynthesis using Granural Synthesis and Effecting all resynthesized sounds using Groove~ objects. – Frequency Modulation/ Additive Synthesis/ Reverb/ Flanger/ Tremolo

2) TouchDesigner and Feedback System were designed to respond to music in real time. This is the result of an afterimage and is the square root of Set Opacity.
