	  trunk/speex/libspeex/mdf.c: Smoothed correlation/energy

2005-05-09 21:03  jm

	* trunk/speex/include/speex/speex_echo.h,
	  trunk/speex/libspeex/mdf.c: Some more regularization work for mdf

2005-05-09 18:15  jm

	* trunk/speex/libspeex/mdf.c: System in underdetermined, trying to
	  work around that.

	* trunk/speex/include/speex/speex_echo.h,
	  trunk/speex/libspeex/mdf.c: Some more AEC cleanup. Played a bit
	  with echo energy estimation.

2005-05-08 00:08  jm

	* trunk/speex/include/speex/speex_echo.h,
	  trunk/speex/include/speex/speex_preprocess.h,
	  trunk/speex/libspeex/mdf.c, trunk/speex/libspeex/preprocess.c:
	  Simplified the code a lot. Put back the denoiser hooks for further
	  cancellation (changed spectral param to float* at least for now).

2005-05-07 08:07  jm

	* trunk/speex/libspeex/mdf.c: trying some ideas for soft-decision
	  DTD based on residual-to-signal ratio

	  don't overwrite input buffer).
