dsp上用c语言实现的aac音频算法的编解码器代码

2003-02-23  menno
	* frontend/: faac.dsp, input.c:
		fixes win32 compilation

	* libfaac/libfaac.dsp, libfaac/psychkni.c,
	plugins/cooledit/FAAC.dsp, plugins/cooledit/Faad.cpp,
	plugins/cooledit/aacInfoLib.dsp:

		now is a lot cleaner to use

2002-12-28  knik
	* include/faac.h:
		new version number

	* libfaac/psychkni.c:
		The distortion limit calculation moved to quantizer.
		Modified block type switch to produce more short blocks.

	* libfaac/aacquant.c:
		The distortion limit calculation moved from psychkni to quantizer to be more
		ISO model compatible.

2002-12-23  knik
	* frontend/main.c:
		added some headers

	* frontend/input.c:
		type size and endian conversion fix

	* configure.in:
