playing with JNDs in vqtrain,c, added log capability to genlsp for lspds

2100 bit version using scaler lsps1-4 and 4096 vq 5-10, run with --lspvq; also experiemental lspres mode that only worked for lsp1-2 and maybe 9-10; and started working on new lspd version

git-svn-id: https://freetel.svn.sourceforge.net/svnroot/freetel/codec2-dev@292 01035d8c-6547-0410-b346-abe4f91aad63
tweaked soem of the LSP scripts while working on dropping LSP bit rate

--lspd mode with scalr LSP differences for lsp1-4, then VQ in log domain of lsp5-10.  Tried a 1024 element VQ but errors propogate so pretty rougfh results

git-svn-id: https://freetel.svn.sourceforge.net/svnroot/freetel/codec2-dev@294 01035d8c-6547-0410-b346-abe4f91aad63
tried LSP differences 1-4 plus VQ in log and linear LSP domain for LSPs4-10 but not happy with results on hts2a

git-svn-id: https://freetel.svn.sourceforge.net/svnroot/freetel/codec2-dev@295 01035d8c-6547-0410-b346-abe4f91aad63
tested lspvq and lspd across 5 utterances with OK results, except for hts2a which is a little worse.  lspd uses lsp differneces 1-4, then 12 bit vq for lsps5-10

have a good quaity delta-t quantiser at about 15 bits/frame, when used for every second frame at 10ms.  Need to work out how to get it down to 10 bit/fr, and if it works with decimated frames

git-svn-id: https://freetel.svn.sourceforge.net/svnroot/freetel/codec2-dev@297 01035d8c-6547-0410-b346-abe4f91aad63
first pass at delta time coding of LSPs in c2sim, sounds pretty good with --lspd --lspdt for 25/15 bits every 20,40ms frame

removed fprintf from run time LSP code, added all/low/high mode for LSP dT

git-svn-id: https://freetel.svn.sourceforge.net/svnroot/freetel/codec2-dev@299 01035d8c-6547-0410-b346-abe4f91aad63
removed fprintf from run time LSP code, added all/low/high mode for LSP dT

first pass at 1400 bit/s simulation

added VQ quantier

JND codebook design code

used jnd codebook for lsps 5-10, gave 0.5 to 1.0 dB snr improvement for lspd & 1400 bit/s

git-svn-id: https://freetel.svn.sourceforge.net/svnroot/freetel/codec2-dev@304 01035d8c-6547-0410-b346-abe4f91aad63
removed old test programs

moved README

bunch of changes to support separate enc/dec at 1400.  Builds but I haven't tested yet

git-svn-id: https://freetel.svn.sourceforge.net/svnroot/freetel/codec2-dev@307 01035d8c-6547-0410-b346-abe4f91aad63
tracking down some subtle differences between c2sim and enc/dec, making progres at 2500 bit/s

git-svn-id: https://freetel.svn.sourceforge.net/svnroot/freetel/codec2-dev@308 01035d8c-6547-0410-b346-abe4f91aad63
c2sim and c2enc/c2dec now match exactly on hts1a and hts2a, many small bugs found and fixed.  Still need to clean up and work on 1400 bit/s
