+= WHAT'S HERE =
+
+This source distribution includes libogg and nothing else. Other modules
+(eg, the modules libvorbis, vorbis-tools for the Vorbis music codec,
+libtheora for the Theora video 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
+
+./doc           Ogg specification and libogg API documents
+
+./win32		Win32 projects and build automation
+
+./macosx	Mac OS X project and build files
+
+= 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 'https://www.xiph.org/ogg/'.
+Up to date technical documents, contact information, source code and
+pre-built utilities may be found there.
+
+BUILDING FROM TARBALL DISTRIBUTIONS:
+
+./configure
+make
+
+and optionally (as root):
+make install
+
+This will install the Ogg libraries (static and shared) into
+/usr/local/lib, includes into /usr/local/include and API
+documentation into /usr/local/share/doc.
+
+BUILDING FROM REPOSITORY SOURCE:
+
+A standard svn build should consist of nothing more than:
+
+./autogen.sh
+make
+
+and as root if desired :
+
+make install
+
+BUILDING ON WIN32:
+
+Use the project file in the win32 directory. It should compile out of the box.
+
+CROSS COMPILING FROM LINUX TO WIN32:
+
+It is also possible to cross compile from Linux to windows using the MinGW
+cross tools and even to run the test suite under Wine, the Linux/*nix
+windows emulator.
+
+On Debian and Ubuntu systems, these cross compiler tools can be installed
+by doing:
+
+    sudo apt-get mingw32 mingw32-binutils mingw32-runtime wine
+
+Once these tools are installed its possible to compile and test by
+executing the following commands, or something similar depending on
+your system:
+
+    ./configure --host=i586-mingw32msvc --target=i586-mingw32msvc \
+         --build=i586-linux
+    make
+    make check
+
+(Build instructions for Ogg codecs such as vorbis are similar and may
+be found in those source modules' README files)

+libvorbis 1.3.2 (2010-11-01) -- "Xiph.Org libVorbis I 20101101 (Schaufenugget)"
+
+ * vorbis: additional proofing against invalid/malicious 
+   streams in floor, residue, and bos/eos packet trimming 
+   code (see SVN for details). 
+ * vorbis: Added programming documentation tree for the 
+   low-level calls
+ * vorbisfile: Correct handling of serial numbers array 
+   element [0] on non-seekable streams
+ * vorbisenc: Back out an [old] AoTuV HF weighting that was 
+   first enabled in 1.3.0; there are a few samples where I 
+   really don't like the effect it causes.
+ * vorbis: return correct timestamp for granule positions 
+   with high bit set.
+ * vorbisfile: the [undocumented] half-rate decode api made no 
+   attempt to keep the pcm offset tracking consistent in seeks. 
+   Fix and add a testing mode to seeking_example.c to torture 
+   test seeking in halfrate mode.  Also remove requirement that 
+   halfrate mode only work with seekable files.
+ * vorbisfile:  Fix a chaining bug in raw_seeks where seeking 
+   out of the current link would fail due to not

+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

+
+BUILDING FROM TRUNK:
+
+Development source is under subversion revision control at 
+https://svn.xiph.org/trunk/vorbis/. You will also need the 
+newest versions of autoconf, automake, libtool and pkg-config 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.
+
+Documentation building requires xsltproc and pdfxmltex.
+
+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.

+ function: normalized modified discrete cosine transform
+           power of two length transform only [64 <= n ]
+ last mod: $Id: mdct.c 16227 2009-07-08 06:58:46Z 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.
