********************************************************************
* *
* THIS FILE IS PART OF THE OggVorbis SOFTWARE CODEC SOURCE CODE. *
* USE, DISTRIBUTION AND REPRODUCTION OF THIS LIBRARY SOURCE IS *
* GOVERNED BY A BSD-STYLE SOURCE LICENSE INCLUDED WITH THIS SOURCE *
* IN 'COPYING'. PLEASE READ THESE TERMS BEFORE DISTRIBUTING. *

********************************************************************
WHAT'S HERE:
This source distribution includes libogg and nothing else. Other modules
(eg, the modules vorbis, vorbis-tools and vorbis-plugins for the Vorbis
codec) contain the codec libraries for use with Ogg bitstreams.
Directory:
./src The source for libogg, a BSD-license inplementation of
the public domain Ogg bitstream format
./include Library API headers and codebooks
./doc Ogg specification documents
./win32 Win32 projects and build automation
./macosx MacOS X project and build files
./macos Classic MacOS 9 projects and build automation
./debian Rules/spec files for building Debian .deb packages
(may not be present, depending on your distribution)
WHAT IS OGG?:
Ogg project codecs use the Ogg bitstream format to arrange the raw,
compressed bitstream into a more robust, useful form. For example,
the Ogg bitstream makes seeking, time stamping and error recovery
possible, as well as mixing several sepearate, concurrent media
streams into a single physical bitstream.
CONTACT:
The Ogg homepage is located at 'http://www.xiph.org/ogg/'.
Up to date technical documents, contact information, source code and
pre-built utilities may be found there.
BUILDING FROM REPOSITORY SOURCE:
A standard svn build should consist of nothing more than:
./autogen.sh
make
and as root if desired :
make install
This will install the Ogg libraries (static and shared) into
/usr/local/lib, includes into /usr/local/include and API manpages
(once we write some) into /usr/local/man.
BUILDING FROM TARBALL DISTRIBUTIONS:
./configure
make
and optionally (as root):
make install
BUILDING RPMS:
RPMs may be built by:
make dist
rpm -ta libogg-<version>.tar.gz
BUILDING ON WIN32:
Use the project file in the win32 directory. It should compile out of the box.
You can also run one of the batch files from the commandline.
E.g.: build_ogg_dynamic
BUILDING ON MACOS 9:
Ogg on MacOS 9 is built using CodeWarrior 5.3. To build it, first
open ogg/mac/libogg.mcp, switch to the "Targets" pane, select
everything, and make the project. In ogg/mac/Output you will now have
both debug and final versions of Ogg shared libraries to link your
projects against.
To build a project using Ogg, add access paths to your CodeWarrior
project for the ogg/include and ogg/mac/Output folders. Be sure that
"interpret DOS and Unix paths" is turned on in your project; it can be
found in the "access paths" pane in your project settings. Now simply
add the shared libraries you need to your project (OggLib at least)
and #include "ogg/ogg.h" wherever you need to acces Ogg functionality.
(Build instructions for Ogg codecs such as vorbis are similar and may
be found in those source modules' README files)

********************************************************************
Vorbis is a general purpose audio and music encoding format
contemporary to MPEG-4's AAC and TwinVQ, the next generation beyond
MPEG audio layer 3. Unlike the MPEG sponsored formats (and other
proprietary formats such as RealAudio G2 and Windows' flavor of the
month), the Vorbis CODEC specification belongs to the public domain.
All the technical details are published and documented, and any
software entity may make full use of the format without license
fee, royalty or patent concerns.
This package contains:
* libvorbis, a BSD-style license software implementation of
the Vorbis specification by the Xiph.Org Foundation
(http://www.xiph.org/)
* libvorbisfile, a BSD-style license convenience library
built on Vorbis designed to simplify common uses
* libvorbisenc, a BSD-style license library that provides a simple,
programmatic encoding setup interface
* example code making use of libogg, libvorbis, libvorbisfile and
libvorbisenc
WHAT'S HERE:
This source distribution includes libvorbis and an example
encoder/player to demonstrate use of libvorbis as well as
documentation on the Ogg Vorbis audio coding format.
You'll need libogg (distributed separately) to compile this library.
A more comprehensive set of utilities is available in the vorbis-tools
package.
Directory:
./lib The source for the libraries, a BSD-license implementation
of the public domain Ogg Vorbis audio encoding format.
./include Library API headers
./debian Rules/spec files for building Debian .deb packages
./doc Vorbis documentation
./examples Example code illustrating programmatic use of libvorbis,
libvorbisfile and libvorbisenc
./mac Codewarrior project files and build tweaks for MacOS.
./macosx Project files for MacOS X.
./win32 Win32 projects files and build automation
./vq Internal utilities for training/building new LSP/residue
and auxiliary codebooks.
CONTACT:
The Ogg homepage is located at 'http://www.xiph.org/ogg/'.
Vorbis's homepage is located at 'http://www.xiph.org/vorbis/'.
Up to date technical documents, contact information, source code and
pre-built utilities may be found there.
The user website for Ogg Vorbis software and audio is http://vorbis.com/
BUILDING FROM TRUNK:
Development source is under subversion revision control at
http://svn.xiph.org/trunk/vorbis/. You will also need the
newest versions of autoconf, automake, and libtool in order
to compile vorbis from development source. A configure script
is provided for you in the source tarball distributions.
[update or checkout latest source]
./autogen.sh
make
and as root if desired:
make install
This will install the vorbis libraries (static and shared) into
/usr/local/lib, includes into /usr/local/include and API manpages
(once we write some) into /usr/local/man.
BUILDING FROM TARBALL DISTRIBUTIONS:
./configure
make
and optionally (as root):
make install
BUILDING RPMS:
after normal configuring:
make dist
rpm -ta libvorbis-<version>.tar.gz
BUILDING ON MACOS 9:
Vorbis on MacOS 9 is built using Metroworks CodeWarrior. To build it,
first verify that the Ogg libraries are already built following the
instructions in the Ogg module README. Open vorbis/mac/libvorbis.mcp,
switch to the "Targets" pane, select everything, and make the project.
Do the same thing to build libvorbisenc.mcp, and libvorbisfile.mcp (in
that order). In vorbis/mac/Output you will now have both debug and final
versions of Vorbis shared libraries to link your projects against.
To build a project using Ogg Vorbis, add access paths to your
CodeWarrior project for the ogg/include, ogg/mac/Output,
vorbis/include, and vorbis/mac/Output folders. Be sure that
"interpret DOS and Unix paths" is turned on in your project; it can
be found in the "access paths" pane in your project settings. Now
simply add the shared libraries you need to your project (OggLib and
VorbisLib at least) and #include "ogg/ogg.h" and "vorbis/codec.h"
wherever you need to access Ogg and Vorbis functionality.

an iterative root polisher (CACM algorithm 283). It *is* possible
to confuse this algorithm into not converging; that should only
happen with absurdly closely spaced roots (very sharp peaks in the
LPC f response) which in turn should be impossible in our use of
the code. If this *does* happen anyway, it's a bug in the floor
finder; find the cause of the confusion (probably a single bin

function: normalized modified discrete cosine transform
power of two length transform only [64 <= n ]
last mod: $Id: mdct.c 13293 2007-07-24 00:09:47Z xiphmont $
Original algorithm adapted long ago from _The use of multirate filter
banks for coding of high quality digital audio_, by T. Sporer,
K. Brandenburg and B. Edler, collection of the European Signal
Processing Conference (EUSIPCO), Amsterdam, June 1992, Vol.1, pp
211-214
The below code implements an algorithm that no longer looks much like
that presented in the paper, but the basic structure remains if you
dig deep enough to see it.
This module DOES NOT INCLUDE code to generate/apply the window
function. Everybody has their own weird favorite including me... I
happen to like the properties of y=sin(.5PI*sin^2(x)), but others may
vehemently disagree.
********************************************************************/
/* this can also be run as an integer transform by uncommenting a
define in mdct.h; the integerization is a first pass and although
it's likely stable for Vorbis, the dynamic range is constrained and
roundoff isn't done (so it's noisy). Consider it functional, but
only a starting point. There's no point on a machine with an FPU */
