* trunk/speex/libspeex/ltp.c, trunk/speex/libspeex/speex.c,
trunk/speex/libspeex/speex.h: Think I figured out the filter
memory (ringing) stuff, not too sure though. Added notion of
target signal and excitation.

* trunk/speex/configure.in, trunk/speex/libspeex/Makefile.am: Forgot
the includes...

* trunk/speex/Makefile.am, trunk/speex/configure.in,
trunk/speex/libspeex/Makefile.am: Makefile system seems to work

trunk/speex/libspeex/lsp_tables_nb.c, trunk/speex/libspeex/ltp.c,

trunk/speex/libspeex/quant_lsp.h, trunk/speex/libspeex/speex.c,
trunk/speex/libspeex/speex.h: Added both LSP and prediction gain
quantization... the code is a bit ugly but it seems to work. For
now we assume a fixed narrowband codebook... Next step: Analysis
by synthesis and excitation quantization

* trunk/speex/libspeex/ltp.c, trunk/speex/libspeex/speex.c,
trunk/speex/libspeex/testenc.c: Save synthesized speech in second
file

* trunk/speex/libspeex/ltp.c, trunk/speex/libspeex/ltp.h,
trunk/speex/libspeex/speex.c: fixed a bug in in-place predictor.
Think most of the framework is now in place...

* trunk/speex/libspeex/ltp.c, trunk/speex/libspeex/ltp.h,
trunk/speex/libspeex/speex.c: 3-tap pitch predictor seems to work

* trunk/speex/libspeex/ltp.c, trunk/speex/libspeex/speex.c,
trunk/speex/libspeex/testenc.c: Implementing a 3-tap long-term
predictor. Also changed frame size to 160

* trunk/speex/libspeex/lsp.c, trunk/speex/libspeex/ltp.c,
trunk/speex/libspeex/ltp.h, trunk/speex/libspeex/speex.c: Added
long-term prediction, fixed subframe bugs, maybe not fully
debugged

* trunk/speex/libspeex/lsp.c, trunk/speex/libspeex/speex.c,
trunk/speex/libspeex/speex.h, trunk/speex/libspeex/testenc.c:
added perceptual weighting filter, bug fixes, fixed warnings
2002-02-15 06:10 jmvalin
* trunk/speex/libspeex/speex.c, trunk/speex/libspeex/speex.h: Fixed
a couple bugs (notably in buffer) and added LSP interpolation

* trunk/speex/libspeex/speex.c, trunk/speex/libspeex/speex.h: Think
I have the LPC->LSP->LPC right this time

* trunk/speex/libspeex/lpc.c, trunk/speex/libspeex/lsp.c,
trunk/speex/libspeex/lsp.h, trunk/speex/libspeex/speex.c: Oops...
now the LSPs are there. Also, lpcSize now represents the order
instead of the filter length (including a[0]=1). Cleaner that way
and more like what everybody else is doing.

* trunk/speex/libspeex/lpc.c, trunk/speex/libspeex/speex.c,
trunk/speex/libspeex/speex.h: integrated LSPs

Initial commit, some LPC stuff is already there...
