Basic Installation
==================
These are generic installation instructions.
The `configure' shell script attempts to guess correct values for
various system-dependent variables used during compilation. It uses
those values to create a `Makefile' in each directory of the package.
It may also create one or more `.h' files containing system-dependent
definitions. Finally, it creates a shell script `config.status' that
you can run in the future to recreate the current configuration, a file
`config.cache' that saves the results of its tests to speed up
reconfiguring, and a file `config.log' containing compiler output
(useful mainly for debugging `configure').
If you need to do unusual things to compile the package, please try
to figure out how `configure' could check whether to do them, and mail
diffs or instructions to the address given in the `README' so they can
be considered for the next release. If at some point `config.cache'
contains results you don't want to keep, you may remove or edit it.
The file `configure.ac' is used to create `configure' by a program
called `autoconf'. You only need `configure.ac' if you want to change
it or regenerate `configure' using a newer version of `autoconf'.
The simplest way to compile this package is:
1. `cd' to the directory containing the package's source code and type
`./configure' to configure the package for your system. If you're
using `csh' on an old version of System V, you might need to type
`sh ./configure' instead to prevent `csh' from trying to execute
`configure' itself.
Running `configure' takes awhile. While running, it prints some
messages telling which features it is checking for.
2. Type `make' to compile the package.
3. Optionally, type `make check' to run any self-tests that come with
the package.
4. Type `make install' to install the programs and any data files and
documentation.
5. You can remove the program binaries and object files from the
source code directory by typing `make clean'. To also remove the
files that `configure' created (so you can compile the package for
a different kind of computer), type `make distclean'. There is
also a `make maintainer-clean' target, but that is intended mainly
for the package's developers. If you use it, you may have to get
all sorts of other programs in order to regenerate files that came
with the distribution.
Compilers and Options
=====================
Some systems require unusual options for compilation or linking that
the `configure' script does not know about. You can give `configure'
initial values for variables by setting them in the environment. Using
a Bourne-compatible shell, you can do that on the command line like
this:
CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure
Or on systems that have the `env' program, you can do it like this:
env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure
Compiling For Multiple Architectures
====================================
You can compile the package for more than one kind of computer at the
same time, by placing the object files for each architecture in their
own directory. To do this, you must use a version of `make' that
supports the `VPATH' variable, such as GNU `make'. `cd' to the
directory where you want the object files and executables to go and run
the `configure' script. `configure' automatically checks for the
source code in the directory that `configure' is in and in `..'.
If you have to use a `make' that does not supports the `VPATH'
variable, you have to compile the package for one architecture at a time
in the source code directory. After you have installed the package for
one architecture, use `make distclean' before reconfiguring for another
architecture.
Installation Names
==================
By default, `make install' will install the package's files in
`/usr/local/bin', `/usr/local/man', etc. You can specify an
installation prefix other than `/usr/local' by giving `configure' the
option `--prefix=PATH'.
You can specify separate installation prefixes for
architecture-specific files and architecture-independent files. If you
give `configure' the option `--exec-prefix=PATH', the package will use
PATH as the prefix for installing programs and libraries.
Documentation and other data files will still use the regular prefix.
In addition, if you use an unusual directory layout you can give
options like `--bindir=PATH' to specify different values for particular
kinds of files. Run `configure --help' for a list of the directories
you can set and what kinds of files go in them.
If the package supports it, you can cause programs to be installed
with an extra prefix or suffix on their names by giving `configure' the
option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
Optional Features
=================
Some packages pay attention to `--enable-FEATURE' options to
`configure', where FEATURE indicates an optional part of the package.
They may also pay attention to `--with-PACKAGE' options, where PACKAGE
is something like `gnu-as' or `x' (for the X Window System). The
`README' should mention any `--enable-' and `--with-' options that the
package recognizes.
For packages that use the X Window System, `configure' can usually
find the X include and library files automatically, but if it doesn't,
you can use the `configure' options `--x-includes=DIR' and
`--x-libraries=DIR' to specify their locations.
Specifying the System Type
==========================
There may be some features `configure' can not figure out
automatically, but needs to determine by the type of host the package
will run on. Usually `configure' can figure that out, but if it prints
a message saying it can not guess the host type, give it the
`--host=TYPE' option. TYPE can either be a short name for the system
type, such as `sun4', or a canonical name with three fields:
CPU-COMPANY-SYSTEM
See the file `config.sub' for the possible values of each field. If
`config.sub' isn't included in this package, then this package doesn't
need to know the host type.
If you are building compiler tools for cross-compiling, you can also
use the `--target=TYPE' option to select the type of system they will
produce code for and the `--build=TYPE' option to select the type of
system on which you are compiling the package.
Sharing Defaults
================
If you want to set default values for `configure' scripts to share,
you can create a site shell script called `config.site' that gives
default values for variables like `CC', `cache_file', and `prefix'.
`configure' looks for `PREFIX/share/config.site' if it exists, then
`PREFIX/etc/config.site' if it exists. Or, you can set the
`CONFIG_SITE' environment variable to the location of the site script.
A warning: not all `configure' scripts look for a site script.
Operation Controls
==================
`configure' recognizes the following options to control how it
operates.
`--cache-file=FILE'
Use and save the results of the tests in FILE instead of
`./config.cache'. Set FILE to `/dev/null' to disable caching, for
debugging `configure'.
`--help'
Print a summary of the options to `configure', and exit.
`--quiet'
`--silent'
`-q'
Do not print messages saying which checks are being made. To
suppress all normal output, redirect it to `/dev/null' (any error
messages will still be shown).
`--srcdir=DIR'
Look for the package's source code in directory DIR. Usually
`configure' can determine that directory automatically.
`--version'
Print the version of Autoconf used to generate the `configure'
script, and exit.
`configure' also accepts some other, not widely useful, options.

libg722_1 0.0.1 - The ITU G.722.1 and G.722.1 Annex codecs, also known
as Siren 7 and Siren 14.
----------------------------------------------------------------------
The ITU G.722.1 specification, and its Annexes, define audio codecs targetted
for wideband speech applications. The variants in G.722.1 support 7kHz and
14kHz bandwidth (16k samples/second and 32k samples/second) audio. They also
cover fixed point and floating point realisations of these codecs.
PLEASE NOTE that patented techniques are used in G.722.1, and Polycom is the
owner of the relevant patents. However, Polycom offers royalty free licences
to use G.722.1 to anyone who complies with a few simple rules. Just contact them,
and you should have no problem using G.722.1 without any payment at all (at least
it was very straightforward for the initial user of this code). You should
check for any licence conflicts with other code in your application - for example,
use in a GPL'ed project might be problematic, unless you run the G.722.1 codec as
a separate process, and your application communicates with it through pipes or
sockets.
This implementation of G.722.1 is adapted from the reference source code
provided by Polycom. Polycom has given its concent for this library to be
distributed as source code, either on its own or as part of a larger package
which they have licenced under their royalty free licencing scheme.
This library has been modified to provide a cleaner API than the reference code,
and to permit many instances of the codec to be run in parallel within a single
process. It uses either fixed point or floating point processing, depending on
how the package is configured. No serious optimisation has been performed to
date. This especially affects the fixed point version of the codec, which uses
some slow and clumsy ways to achieve a bit exact result. Optimisation is planned.
The fixed point version of the codec passes the ITU test vectors. The floating
point version produces results which vary a little with the compiler and compiler
optimisation level chosen. This is normal variability for a codec of this type. On
the development machine disabling the "-O2" and "-ffast-math" optimisations
for the floating point version results in an exact match with the ITU test vectors.
By default, ./configure will configure the codec to used floating point
processing for processors with fast floating point hardware, or fixed point
processing for a selection of well know fixed point DSPs and embedded processors.
The command line option "--enable-fixed-point" will force ./configure to enable
fixed point processing.
To test the codec with the ITU test vectors, get the ITU package
T-REC-G.722.1-200505-I!!SOFT-ZST-E.zip and place it in top level directory
for this project. Then run unpack_g722_1_data.sh . This should uppack the
test vectors into test-data/itu/g722_1. Run configure with the "--enable-tests"
option, and build the software. Then run regression_tests.sh in the tests
directory.

## This next piece of magic avoids the `deleted header file' problem.
## The problem is that when a header file which appears in a .P file
## is deleted, the dependency causes make to die (because there is

## dummy dependencies for each header file. Too bad gcc doesn't do

Purpose: Convert Reversed MLT (Modulated Lapped Transform) Coefficients to Samples
The "Reversed MLT" is an overlapped block transform which uses even symmetry
on the left, odd symmetry on the right and a Type IV DCT as the block transform.
It is thus similar to a MLT which uses odd symmetry on the left, even symmetry
on the right and a Type IV DST as the block transform. In fact, it is equivalent
to reversing the order of the samples, performing an MLT and then negating all
the even-numbered coefficients.

*
* The basis functions are

* cos(PI*(t+0.5)*(k+0.5)/block_length)
*
* for time t and basis function number k. Due to the symmetry of the expression
* in t and k, it is clear that the forward and inverse transforms are the same.

Purpose: Convert Samples to Reversed MLT (Modulated Lapped Transform) Coefficients
The "Reversed MLT" is an overlapped block transform which uses even symmetry
on the left, odd symmetry on the right and a Type IV DCT as the block transform.
It is thus similar to a MLT which uses odd symmetry on the left, even symmetry
on the right and a Type IV DST as the block transform. In fact, it is equivalent
to reversing the order of the samples, performing an MLT and then negating all
the even-numbered coefficients.
