+                  GNU LIBRARY GENERAL PUBLIC LICENSE
+                       Version 2, June 1991
+
+ Copyright (C) 1991 Free Software Foundation, Inc.
+ 51 Franklin Street, Fifth Floor, Boston, MA  02110-1301  USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+[This is the first released version of the library GPL.  It is
+ numbered 2 because it goes with version 2 of the ordinary GPL.]
+
+                            Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+Licenses are intended to guarantee your freedom to share and change
+free software--to make sure the software is free for all its users.
+
+  This license, the Library General Public License, applies to some
+specially designated Free Software Foundation software, and to any
+other libraries whose authors decide to use it.  You can use it for
+your libraries, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if
+you distribute copies of the library, or if you modify it.
+
+  For example, if you distribute copies of the library, whether gratis
+or for a fee, you must give the recipients all the rights that we gave
+you.  You must make sure that they, too, receive or can get the source
+code.  If you link a program with the library, you must provide
+complete object files to the recipients so that they can relink them
+with the library, after making changes to the library and recompiling
+it.  And you must show them these terms so they know their rights.
+
+  Our method of protecting your rights has two steps: (1) copyright
+the library, and (2) offer you this license which gives you legal
+permission to copy, distribute and/or modify the library.
+
+  Also, for each distributor's protection, we want to make certain
+that everyone understands that there is no warranty for this free
+library.  If the library is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original
+version, so that any problems introduced by others will not reflect on
+the original authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that companies distributing free
+software will individually obtain patent licenses, thus in effect
+transforming the program into proprietary software.  To prevent this,
+we have made it clear that any patent must be licensed for everyone's
+free use or not licensed at all.
+
+  Most GNU software, including some libraries, is covered by the ordinary
+GNU General Public License, which was designed for utility programs.  This
+license, the GNU Library General Public License, applies to certain
+designated libraries.  This license is quite different from the ordinary
+one; be sure to read it in full, and don't assume that anything in it is
+the same as in the ordinary license.
+
+  The reason we have a separate public license for some libraries is that
+they blur the distinction we usually make between modifying or adding to a
+program and simply using it.  Linking a program with a library, without
+changing the library, is in some sense simply using the library, and is
+analogous to running a utility program or application program.  However, in
+a textual and legal sense, the linked executable is a combined work, a
+derivative of the original library, and the ordinary General Public License
+treats it as such.
+
+  Because of this blurred distinction, using the ordinary General
+Public License for libraries did not effectively promote software
+sharing, because most developers did not use the libraries.  We
+concluded that weaker conditions might promote sharing better.
+
+  However, unrestricted linking of non-free programs would deprive the
+users of those programs of all benefit from the free status of the
+libraries themselves.  This Library General Public License is intended to
+permit developers of non-free programs to use free libraries, while
+preserving your freedom as a user of such programs to change the free
+libraries that are incorporated in them.  (We have not seen how to achieve
+this as regards changes in header files, but we have achieved it as regards
+changes in the actual functions of the Library.)  The hope is that this
+will lead to faster development of free libraries.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.  Pay close attention to the difference between a
+"work based on the library" and a "work that uses the library".  The
+former contains code derived from the library, while the latter only
+works together with the library.
+
+  Note that it is possible for a library to be covered by the ordinary
+General Public License rather than by this special one.
+
+                  GNU LIBRARY GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License Agreement applies to any software library which
+contains a notice placed by the copyright holder or other authorized
+party saying it may be distributed under the terms of this Library
+General Public License (also called "this License").  Each licensee is
+addressed as "you".
+
+  A "library" means a collection of software functions and/or data
+prepared so as to be conveniently linked with application programs
+(which use some of those functions and data) to form executables.
+
+  The "Library", below, refers to any such software library or work
+which has been distributed under these terms.  A "work based on the
+Library" means either the Library or any derivative work under
+copyright law: that is to say, a work containing the Library or a
+portion of it, either verbatim or with modifications and/or translated
+straightforwardly into another language.  (Hereinafter, translation is
+included without limitation in the term "modification".)
+
+  "Source code" for a work means the preferred form of the work for
+making modifications to it.  For a library, complete source code means
+all the source code for all modules it contains, plus any associated
+interface definition files, plus the scripts used to control compilation
+and installation of the library.
+
+  Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running a program using the Library is not restricted, and output from
+such a program is covered only if its contents constitute a work based
+on the Library (independent of the use of the Library in a tool for
+writing it).  Whether that is true depends on what the Library does
+and what the program that uses the Library does.
+  
+  1. You may copy and distribute verbatim copies of the Library's
+complete source code as you receive it, in any medium, provided that
+you conspicuously and appropriately publish on each copy an
+appropriate copyright notice and disclaimer of warranty; keep intact
+all the notices that refer to this License and to the absence of any
+warranty; and distribute a copy of this License along with the
+Library.
+
+  You may charge a fee for the physical act of transferring a copy,
+and you may at your option offer warranty protection in exchange for a
+fee.
+
+  2. You may modify your copy or copies of the Library or any portion
+of it, thus forming a work based on the Library, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) The modified work must itself be a software library.
+
+    b) You must cause the files modified to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    c) You must cause the whole of the work to be licensed at no
+    charge to all third parties under the terms of this License.
+
+    d) If a facility in the modified Library refers to a function or a
+    table of data to be supplied by an application program that uses
+    the facility, other than as an argument passed when the facility
+    is invoked, then you must make a good faith effort to ensure that,
+    in the event an application does not supply such function or
+    table, the facility still operates, and performs whatever part of
+    its purpose remains meaningful.
+
+    (For example, a function in a library to compute square roots has
+    a purpose that is entirely well-defined independent of the
+    application.  Therefore, Subsection 2d requires that any
+    application-supplied function or table used by this function must
+    be optional: if the application does not supply it, the square
+    root function must still compute square roots.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Library,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Library, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote
+it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Library.
+
+In addition, mere aggregation of another work not based on the Library
+with the Library (or with a work based on the Library) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may opt to apply the terms of the ordinary GNU General Public
+License instead of this License to a given copy of the Library.  To do
+this, you must alter all the notices that refer to this License, so
+that they refer to the ordinary GNU General Public License, version 2,
+instead of to this License.  (If a newer version than version 2 of the
+ordinary GNU General Public License has appeared, then you can specify
+that version instead if you wish.)  Do not make any other change in
+these notices.
+
+  Once this change is made in a given copy, it is irreversible for
+that copy, so the ordinary GNU General Public License applies to all
+subsequent copies and derivative works made from that copy.
+
+  This option is useful when you wish to copy part of the code of
+the Library into a program that is not a library.
+
+  4. You may copy and distribute the Library (or a portion or
+derivative of it, under Section 2) in object code or executable form
+under the terms of Sections 1 and 2 above provided that you accompany
+it with the complete corresponding machine-readable source code, which
+must be distributed under the terms of Sections 1 and 2 above on a
+medium customarily used for software interchange.
+
+  If distribution of object code is made by offering access to copy
+from a designated place, then offering equivalent access to copy the
+source code from the same place satisfies the requirement to
+distribute the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  5. A program that contains no derivative of any portion of the
+Library, but is designed to work with the Library by being compiled or
+linked with it, is called a "work that uses the Library".  Such a
+work, in isolation, is not a derivative work of the Library, and
+therefore falls outside the scope of this License.
+
+  However, linking a "work that uses the Library" with the Library
+creates an executable that is a derivative of the Library (because it
+contains portions of the Library), rather than a "work that uses the
+library".  The executable is therefore covered by this License.
+Section 6 states terms for distribution of such executables.
+
+  When a "work that uses the Library" uses material from a header file
+that is part of the Library, the object code for the work may be a
+derivative work of the Library even though the source code is not.
+Whether this is true is especially significant if the work can be
+linked without the Library, or if the work is itself a library.  The
+threshold for this to be true is not precisely defined by law.
+
+  If such an object file uses only numerical parameters, data
+structure layouts and accessors, and small macros and small inline
+functions (ten lines or less in length), then the use of the object
+file is unrestricted, regardless of whether it is legally a derivative
+work.  (Executables containing this object code plus portions of the
+Library will still fall under Section 6.)
+
+  Otherwise, if the work is a derivative of the Library, you may
+distribute the object code for the work under the terms of Section 6.
+Any executables containing that work also fall under Section 6,
+whether or not they are linked directly with the Library itself.
+
+  6. As an exception to the Sections above, you may also compile or
+link a "work that uses the Library" with the Library to produce a
+work containing portions of the Library, and distribute that work
+under terms of your choice, provided that the terms permit
+modification of the work for the customer's own use and reverse
+engineering for debugging such modifications.
+
+  You must give prominent notice with each copy of the work that the
+Library is used in it and that the Library and its use are covered by
+this License.  You must supply a copy of this License.  If the work
+during execution displays copyright notices, you must include the
+copyright notice for the Library among them, as well as a reference
+directing the user to the copy of this License.  Also, you must do one
+of these things:
+
+    a) Accompany the work with the complete corresponding
+    machine-readable source code for the Library including whatever
+    changes were used in the work (which must be distributed under
+    Sections 1 and 2 above); and, if the work is an executable linked
+    with the Library, with the complete machine-readable "work that
+    uses the Library", as object code and/or source code, so that the
+    user can modify the Library and then relink to produce a modified
+    executable containing the modified Library.  (It is understood
+    that the user who changes the contents of definitions files in the
+    Library will not necessarily be able to recompile the application
+    to use the modified definitions.)
+
+    b) Accompany the work with a written offer, valid for at
+    least three years, to give the same user the materials
+    specified in Subsection 6a, above, for a charge no more
+    than the cost of performing this distribution.
+
+    c) If distribution of the work is made by offering access to copy
+    from a designated place, offer equivalent access to copy the above
+    specified materials from the same place.
+
+    d) Verify that the user has already received a copy of these
+    materials or that you have already sent this user a copy.
+
+  For an executable, the required form of the "work that uses the
+Library" must include any data and utility programs needed for
+reproducing the executable from it.  However, as a special exception,
+the source code distributed need not include anything that is normally
+distributed (in either source or binary form) with the major
+components (compiler, kernel, and so on) of the operating system on
+which the executable runs, unless that component itself accompanies
+the executable.
+
+  It may happen that this requirement contradicts the license
+restrictions of other proprietary libraries that do not normally
+accompany the operating system.  Such a contradiction means you cannot
+use both them and the Library together in an executable that you
+distribute.
+
+  7. You may place library facilities that are a work based on the
+Library side-by-side in a single library together with other library
+facilities not covered by this License, and distribute such a combined
+library, provided that the separate distribution of the work based on
+the Library and of the other library facilities is otherwise
+permitted, and provided that you do these two things:
+
+    a) Accompany the combined library with a copy of the same work
+    based on the Library, uncombined with any other library
+    facilities.  This must be distributed under the terms of the
+    Sections above.
+
+    b) Give prominent notice with the combined library of the fact
+    that part of it is a work based on the Library, and explaining
+    where to find the accompanying uncombined form of the same work.
+
+  8. You may not copy, modify, sublicense, link with, or distribute
+the Library except as expressly provided under this License.  Any
+attempt otherwise to copy, modify, sublicense, link with, or
+distribute the Library is void, and will automatically terminate your
+rights under this License.  However, parties who have received copies,
+or rights, from you under this License will not have their licenses
+terminated so long as such parties remain in full compliance.
+
+  9. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Library or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Library (or any work based on the
+Library), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Library or works based on it.
+
+  10. Each time you redistribute the Library (or any work based on the
+Library), the recipient automatically receives a license from the
+original licensor to copy, distribute, link with or modify the Library
+subject to these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  11. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Library at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Library by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Library.
+
+If any portion of this section is held invalid or unenforceable under any
+particular circumstance, the balance of the section is intended to apply,
+and the section as a whole is intended to apply in other circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  12. If the distribution and/or use of the Library is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Library under this License may add

+
+Each version is given a distinguishing version number.  If the Library

+write to the author to ask for permission.  For software which is
+copyrighted by the Free Software Foundation, write to the Free

+
+                            NO WARRANTY

+           How to Apply These Terms to Your New Libraries
+
+  If you develop a new library, and you want it to be of the greatest
+possible use to the public, we recommend making it free software that
+everyone can redistribute and change.  You can do so by permitting
+redistribution under these terms (or, alternatively, under the terms of the
+ordinary General Public License).
+
+  To apply these terms, attach the following notices to the library.  It is
+safest to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least the
+"copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the library's name and a brief idea of what it does.>

+    This library is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of

@@ -0,0 +1,188 @@
+openal-soft-1.17.2:
+
+    Implemented device enumeration for OSSv4.
+
+    Fixed building on OSX.
+
+    Fixed building on non-Windows systems without POSIX-2008.
+
+    Fixed Dedicated Dialog and Dedicated LFE effect output.
+
+    Added a build option to override the share install dir.
+
+    Added a build option to static-link libgcc for MinGW.
+
+openal-soft-1.17.1:
+
+    Fixed building with JACK and without PulseAudio.
+
+    Fixed building on FreeBSD.
+
+    Fixed the ALSA backend's allow-resampler option.
+
+    Fixed handling of inexact ALSA period counts.
+
+    Altered device naming scheme on Windows backends to better match other
+    drivers.
+
+    Updated the CoreAudio backend to use the AudioComponent API. This clears up
+    deprecation warnings for OSX 10.11, although requires OSX 10.6 or newer.
+
+openal-soft-1.17.0:
+
+    Implemented a JACK playback backend.
+
+    Implemented the AL_EXT_BFORMAT and AL_EXT_MULAW_BFORMAT extensions.
+
+    Implemented the ALC_SOFT_HRTF extension.
+
+    Implemented C, SSE3, and SSE4.1 based 4- and 8-point Sinc resamplers.
+
+    Implemented a C and SSE based band-limited Sinc resampler. This does 12- to
+    24-point Sinc resampling, and performs anti-aliasing.
+
+    Implemented B-Format output support for the wave file writer. This creates
+    FuMa-style first-order Ambisonics wave files (AMB format).
+
+    Implemented a stereo-mode config option for treating stereo modes as either
+    speakers or headphones.
+
+    Implemented per-device configuration options.
+
+    Fixed handling of PulseAudio and MMDevAPI devices that have identical
+    descriptions.
+
+    Fixed a potential lockup when stopping playback of suspended PulseAudio devices.
+
+    Fixed logging of Unicode characters on Windows.
+
+    Fixed 5.1 surround sound channels. By default it will now use the side
+    channels for the surround output. A configuration using rear channels is
+    still available.
+
+    Fixed the QSA backend potentially altering the capture format.
+
+    Fixed detecting MMDevAPI's default device.
+
+    Fixed returning the default capture device name.
+
+    Fixed mixing property calculations when deferring context updates.
+
+    Altered the behavior of alcSuspendContext and alcProcessContext to better
+    match certain Windows drivers.
+
+    Altered the panning algorithm, utilizing Ambisonics for better side and
+    back positioning cues with surround sound output.
+
+    Improved support for certain older Windows apps.
+
+    Improved the alffplay example to support surround sound streams.
+
+    Improved support for building as a sub-project.
+
+    Added an HRTF playback example.
+
+    Added a tone generator output test.
+
+    Added a toolchain to help with cross-compiling to Android.
+
+openal-soft-1.16.0:
+
+    Implemented EFX Chorus, Flanger, Distortion, Equalizer, and Compressor
+    effects.
+
+    Implemented high-pass and band-pass EFX filters.
+
+    Implemented the high-pass filter for the EAXReverb effect.
+
+    Implemented SSE2 and SSE4.1 linear resamplers.
+
+    Implemented Neon-enhanced non-HRTF mixers.
+
+    Implemented a QSA backend, for QNX.
+
+    Implemented the ALC_SOFT_pause_device, AL_SOFT_deferred_updates,
+    AL_SOFT_block_alignment, AL_SOFT_MSADPCM, and AL_SOFT_source_length
+    extensions.
+
+    Fixed resetting mmdevapi backend devices.
+
+    Fixed clamping when converting 32-bit float samples to integer.
+
+    Fixed modulation range in the Modulator effect.
+
+    Several fixes for the OpenSL playback backend.
+
+    Fixed device specifier names that have Unicode characters on Windows.
+
+    Added support for filenames and paths with Unicode (UTF-8) characters on
+    Windows.
+
+    Added support for alsoft.conf config files found in XDG Base Directory
+    Specification locations (XDG_CONFIG_DIRS and XDG_CONFIG_HOME, or their
+    defaults) on non-Windows systems.
+
+    Added a GUI configuration utility (requires Qt 4.8).
+
+    Added support for environment variable expansion in config options (not
+    keys or section names).
+
+    Added an example that uses SDL2 and ffmpeg.
+
+    Modified examples to use SDL_sound.
+
+    Modified CMake config option names for better sorting.
+
+    HRTF data sets specified in the hrtf_tables config option may now be
+    relative or absolute filenames.
+
+    Made the default HRTF data set an external file, and added a data set for
+    48khz playback in addition to 44.1khz.
+
+    Added support for C11 atomic methods.
+
+    Improved support for some non-GNU build systems.
+
+openal-soft-1.15.1:
+
+    Fixed a regression with retrieving the source's AL_GAIN property.
+
+openal-soft-1.15:
+
+    Fixed device enumeration with the OSS backend.
+
+    Reorganized internal mixing logic, so unneeded steps can potentially be
+    skipped for better performance.
+
+    Removed the lookup table for calculating the mixing pans. The panning is
+    now calculated directly for better precision.
+
+    Improved the panning of stereo source channels when using stereo output.
+
+    Improved source filter quality on send paths.
+
+    Added a config option to allow PulseAudio to move streams between devices.
+
+    The PulseAudio backend will now attempt to spawn a server by default.
+
+    Added a workaround for a DirectSound bug relating to float32 output.
+
+    Added SSE-based mixers, for HRTF and non-HRTF mixing.
+
+    Added support for the new AL_SOFT_source_latency extension.
+
+    Improved ALSA capture by avoiding an extra buffer when using sizes
+    supported by the underlying device.
+
+    Improved the makehrtf utility to support new options and input formats.
+
+    Modified the CFLAGS declared in the pkg-config file so the "AL/" portion of
+    the header includes can optionally be omitted.
+
+    Added a couple example code programs to show how to apply reverb, and
+    retrieve latency.
+
+    The configuration sample is now installed into the share/openal/ directory
+    instead of /etc/openal.
+
+    The configuration sample now gets installed by default.

+ * int (*ptr)[10];
+ * const int (*cptr)[10] = ptr;
+ *
+ * is not allowed and most compilers will generate noisy warnings about
+ * incompatible types, even though it just makes the array elements const.
+ * Clang will allow it if you make the array type a typedef, like this:
+ *
+ * typedef int int10[10];
+ * int10 *ptr;
+ * const int10 *cptr = ptr;
+ *
+ * however GCC does not and still issues the incompatible type warning. The
+ * "proper" way to fix it is to add an explicit cast for the constified type,
+ * but that removes the vast majority of otherwise useful type-checking you'd
+ * get, and runs the risk of improper casts if types are later changed. Leaving
+ * it non-const can also be an issue if you use it as a function parameter, and
+ * happen to have a const type as input (and also reduce the capabilities of
+ * the compiler to better optimize the function).
+ *
+ * So to work around the problem, we use a macro. The macro first assigns the
+ * incoming variable to the specified non-const type to ensure it's the correct
+ * type, then casts the variable as the desired constified type. Very ugly, but
+ * I'd rather not have hundreds of lines of warnings because I want to tell the
+ * compiler that some array(s) can't be changed by the code, or have lots of
+ * error-prone casts.

+Source Install
+==============
+
+To install OpenAL Soft, use your favorite shell to go into the build/
+directory, and run:
+
+cmake ..
+
+Assuming configuration went well, you can then build it, typically using GNU
+Make (KDevelop, MSVC, and others are possible depending on your system setup
+and CMake configuration).
+
+Please Note: Double check that the appropriate backends were detected. Often,
+complaints of no sound, crashing, and missing devices can be solved by making
+sure the correct backends are being used. CMake's output will identify which
+backends were enabled.
+
+For most systems, you will likely want to make sure ALSA, OSS, and PulseAudio
+were detected (if your target system uses them). For Windows, make sure
+DirectSound was detected.
+
+
+Utilities
+=========
+
+The source package comes with an informational utility, openal-info, and is
+built by default. It prints out information provided by the ALC and AL sub-
+systems, including discovered devices, version information, and extensions.
+
+
+Configuration
+=============
+
+OpenAL Soft can be configured on a per-user and per-system basis. This allows
+users and sysadmins to control information provided to applications, as well
+as application-agnostic behavior of the library. See alsoftrc.sample for
+available settings.
+
+
+Acknowledgements
+================
+
+Special thanks go to:
+
+Creative Labs for the original source code this is based off of.
+
+Christopher Fitzgerald for the current reverb effect implementation, and
+helping with the low-pass and HRTF filters.
+
+Christian Borss for the 3D panning code previous versions used as a base.
+
+Ben Davis for the idea behind a previous version of the click-removal code.
+
+Richard Furse for helping with my understanding of Ambisonics that is used by
+the various parts of the library.
