	  trunk/speex/libspeex/speex_echo.h,
	  trunk/speex/libspeex/speex_preprocess.h: smallft.h doesn't need to

	  trunk/speex/libspeex/speex_denoise.h,
	  trunk/speex/libspeex/speex_preprocess.h,

2003-09-16 01:51  jm

	* trunk/speex/libspeex/denoise.c: prevented the AGC from causing

2003-08-24 04:28  jm

	* trunk/speex/libspeex/nb_celp.c, trunk/speex/libspeex/sb_celp.c:
	  Allow setting the decode submode in case it's not embedded in the
