근데 내 노트북이 요구사항이 되나?
반대로.. 굳이 저런 요구사항이 필요로 되는 이유가 멀까?

aptitude 패키지를 설치해서 해당 유틸리티로 확인하는게 가장 확실한 듯

설정에서 한글 입력기를 추가로 설정을 해주어야 한다.
외산 노트북이라 한영키가 없다 보니 기본 설정으로는 안되고
오른쪽 alt 를 추가해주어도 한영 변환이나
오른쪽 ctrl로 한자 변환이 되지 않는다 -_ㅠ
ibus라 그런가.. 다른걸로 해봐야하나?

USB sd 리더에서 해보긴 했는데
fat32 였던지라 넣으면 바로 인식해서 마운트 되는 바람에
수동으로 umount를 해주어야 했지만 그래도 꽤 편하게 쓸 수 있는 툴
woeusbgui로 실행하면 된다.

노트북에 이어폰 꼽고, 마이크에 가져다 대고 jaaa를 실행하니
1k에 피크가 뜨긴 한데.. 이걸 어떻게 프로그램적으로 검사하지?
그리고 저 망할(?) 2k에는 왜 뜨는거야.. FFT 한계인가 문제인가? ㅠㅠ
