Moved the remaining of misc.h into arch.h

Better control of the pitch gain to prevent potential instabilities from
jm
2006-05-20
excitation and target are now 16-bit (were 32) in the encoder
jm
2006-05-16
decoder excitation now in 16-bit precision (was 32), which saves quite a bit
jm
2006-04-08
weighted signal now in 16-bit precision, saving 500 bytes in the encoder state
jm
2006-03-18
new experimental comb filter code

2005-08-31
Improved Doxygen comments

2005-05-02
Added some control on the aggressiveness of the pitch predictor in the form of

More work on fixed-point operators
jm
2005-04-22
Fixed-point improvements (moved some stuff to 16-bit arithmetic)
jm
2004-07-14
Moved all the includes from /usr/include to /usr/include/speex
jm
2003-12-05
Added const's all over the place

fixed-point: pitch gain stuff
jm
2003-11-28
fixed-point: some work on pitch gain, fixed a packet-loss bug
jm
2003-11-25
fixed-point: done quantizing open-loop pitch
jm
2003-10-08
fixed-point: converted all signals to spx_sig_t
jm
2003-10-08
first step in fixed-point port, converted the LPC filters
jm
2003-05-14
Merged an experimental (and non-standard) 4.8 kbps mode. Note that this
jm

Gain codebook also converted to signed char.

2003-01-23
Fixed a bunch of typos pointed to by: larry@doolittle.boa.org
jm
2003-01-06
Think I made the stack operations more portable in case sizeof(int) !=
jm
2002-11-28
Many improvements (hopefully) to packet loss concealing, part of it from a

The temp stack is now void* instead of float*

2002-10-23
Compute impulse response of "perceptual synthesis filter" globally and

Changed license to BSD

Cleaned up vocoder mode...
jmvalin
2002-07-29
added encoder complexity option

Cleanup
jmvalin
2002-07-02
Cleaned up unused stuff and licensed all codebooks under the BSD license
jmvalin
2002-06-11
Added low bit-rate (8 kbps) narrowband mode. It is still sub-optimal but
jmvalin
2002-06-08
Implemented an n-best open-loop pitch search to speed up the closed-loop
jmvalin
2002-05-29
Added a post-filter for narrowband (and thus 0-4 kHz in wideband)
jmvalin
2002-05-19
FrameBits renamed to SpeexBits and a "lost" argument was added to the
jmvalin
2002-05-03
bits.h was renamed to speex_bits to prevent name clashes
jmvalin
2002-04-29
Decoder back in sync with the encoder
jmvalin
2002-04-24
Made the initial pitch search open-loop. Removed some modulo and devide
jmvalin
2002-04-23
Many, many updates. Better split-VQ search, better handling of pitch for
jmvalin
2002-03-15
More wideband stuff...
jmvalin
2002-03-14
Think the modularity stuff is mostly done...
jmvalin
2002-03-14
Cleaning up the code and making it easier to switch algorithms...
jmvalin
2002-03-13
Decoding of pitch (still untested)
jmvalin
2002-03-13
Code cleanup, removed warnings
jmvalin
2002-03-11
The encoder (testenc) now produces a bitstream
jmvalin
2002-03-08
The code is getting horribly messy, but there's too much stuff that needs
jmvalin

Pitch prediction stuff...
jmvalin
2002-02-27
Added 3-tap pitch predictor by analysis by synthesis
jmvalin
2002-02-19
Checking in license stuff
jmvalin
2002-02-18
Added both LSP and prediction gain quantization... the code is a bit ugly
jmvalin
2002-02-17
fixed a bug in in-place predictor. Think most of the framework is now in
jmvalin

3-tap pitch predictor seems to work
