To rename an Xcode 2.5 project, do the following:

1. Close the project in Xcode
2. Duplicate the project directory in the Finder by pressing Command-D.
3. Rename the folder
4. Open the folder and rename the “.xcodeproject” file
5. Delete the “Build” sub folder, if there is one
6. Open the renamed .xcodeproject file
7. On the left in the “Groups&Files” list, expand the “Targets” group, double click on the target that still has your old project filename. Rename it under the “General”-tab in the window that opens.
8. Select “Clean all targets” from the “Build” menu, keep the boxes checked, and click “Clean”.
9. Build and run your project.

아이폰에서 특정 주파수의 intensity만을 가지고 오는 방법은 크게 두가지.

1. fmod (sound library 사용 ! )

http://www.fmod.org

프로그램폴더\FMOD SoundSystem\FMOD Programmers API Win32_4.32.05\documentation\fmodex.chm 에 도움말이 나와있음.

2. fft 사용 ! 

주파수를 에너지한 후에 특정 주파수 지우고 inverse fft.

opencv 라이브러리 xCode 에 설정하기

Build OpenCV-2.0.0 for iPhone OS 3.1 (simulator and device) according to this good tutorial.
Under Target > Build > Linking > Other Linker Flags (These flags are passed with all linker invocations. [OTHER_LDFLAGS]) add Build Setting Conditions for Any iPhone Device/Any Architecture and Any iPhone OS Simulator/Any Architecture. Add the flags-lstdc++, -lz, $(SRCROOT)/OpenCV/opencv_{device,simulator}/lib/libcv.a andlibcxcore.a
Under Target > Build > Search Paths > Header Search Paths (This is a list of paths to folders to be searched by the compiler for included or imported header files when compiling C, Objective-C, C++, or Objective-C++. Paths are delimited by whitespace, so any paths with spaces in them need to be properly quoted. [HEADER_SEARCH_PATHS, -I]) add Build Setting Conditions for Any iPhone Device/Any Architecture and Any Iphone OS Simulator/Any Architecture. Add the path$(SRCROOT)/OpenCV/opencv_{device,simulator}/include without recursive flag.
#import <opencv/cv.h>

<주의사항> 경로에 빈칸이 있는경우 적절히 쿼트를 해줘야함. 이것때문에 한시간이나 삽질했음. :^)
