Due to the license <License.htm>, so I can't make it public,
Last November, I decided to register mac-port at SourceForge,
so I had to choose an open source license, so I chosen LGPL
for this mac-port. It is close to the original license,
but doesn't get the permission from the original author, Matt.
This license would be changed when the author asks in the
future.

-------------------
Requirement
-------------------
NASM - Netwide Assembler, for compiling the asm source.
-------------------
Compile
-------------------
$ ./configure
$ make
There is an option named --enable-backward for backward compatibility.
-------------------
Install
-------------------
$ make install
(need to be root)
then the lib will be installed to the default usr lib of your system (/usr/lib)
named libmac.so*, the console frontend (now it is statically linked) to /usr/bin named
mac, and some header files to /usr/include/mac.
There is also a sample analyzing program, located in src/Examples/Analyzer/Sample1,
which displays some information of the specified file. It is not installed.
Enjoy It!

MAC: short for Monkey's Audio Codec, a lossless audio codec (almost with the .ape extension).
3.99 Update 4 build 4 (2005/08/31):
* add big endian support, but no ASM sources, so the speed will
be a little slower. But it is really great that it can run at many
Big Endian OSes. Enjoy it!
* fixed the bug of conversion from WCS to MBS for non-ascii characters
in UTF-8 locale.
3.99 Update 4 build 3 (2005/04/14):
* 3.99 update 4 build 3 released, this is a bug fix version.
* fixed the bug of file opening error when no permission to write.
3.99 Update 4 build 2 (2005/04/06):
* 3.99 update 4 build 2 released.
* fixed the bug of opening APE files as Read Only, should be
Reading and Writing for tag editing support.
* fixed some other minor bugs, see ChangeLog for more details.
3.99 Update 4 (2004/05/12):
* 3.99 update 4 Linux port completed.
3.99 (2004/05/02):
* 3.99 Linux port completed.
3.98a (2004/02/17):
* 3.98a Linux port completed.
* mainly handles the wchar_t related codes.
* fixed some wrong multi bytes and wide char conversions.
3.96 (2003/07/27):
My first build @ a Debian SID box.

MAC: short for Monkey's Audio Codec, a lossless audio codec (almost with the .ape extension).
This is the MAC Linux port. I have added the autoconf and automake stuff and
made some slight changes for the codes.
Since 3.99 update 4 build 4, mac-port has support for big endian platforms,
and has been tested in MAC OSX 10.4, Linux PowerPC and SunOS Sparc,
but need more tests in more OSes and more Platforms.

* ASM in other platforms, PowerPC, Sparc, etc.
[*] Better compatibilily of cross platform.
* avoid the warning of "this decimal constant is unsigned only in ISO C90"

## -MM, not -M (despite what the docs say).
## - Using -M directly means running the compiler twice (even worse

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

/***************************************************************************************
Analyze - Sample 1
Copyright (C) 2000-2001 by Matthew T. Ashland All Rights Reserved.
Feel free to use this code in any way that you like.
This example opens an APE file and displays some basic information about it. To use it,
just type Sample 1.exe followed by a file name and it'll display information about that
file.
Notes for use in a new project:
-you need to include "MACLib.lib" in the included libraries list
-life will be easier if you set the [MAC SDK]\\Shared directory as an include
directory and an additional library input path in the project settings
-set the runtime library to "Mutlithreaded"
WARNING:
-This class driven system for using Monkey's Audio is still in development, so
I can't make any guarantees that the classes and libraries won't change before
everything gets finalized. Use them at your own risk.

History:
Monkey's Audio 3.99 Update 4
1. Fixed: Decoder could erroneously report a CRC error on the last frame of some files.
Monkey's Audio 3.99 Update 3
1. Changed: Worked on making data types more standard / cross-platform friendly.
2. Changed: Switched code from tab-based to space based. (may still be some out-of-whack formatting)
3. Fixed: Building ID3 tags could cause a crash.
4. Fixed: APL builder treated the last part of a CUE time as a hundreth of a second instead of as a frame. (1 / 75 of a second)
5. Fixed: File Info dialog used by Winamp plugin wouldn't accept / save Unicode tag values properly.
6. Fixed: APL files could output noise or silence at the end of the file in some cases.
Monkey's Audio 3.99 Update 2
1. Fixed: Possible buffer overflow attack weakness in APE tagging code.
2. Fixed: MACDll.dll was not doing ANSI to Unicode conversions properly.
3. Changed: Added Unicode versions of interface wrappers to MACDll.dll.
4. Changed: Updated Winamp plugin to better handle Unicode.
5. Changed: Removed peak-level normalize from file and Winamp plugin. (newer players can do normalize / replay gain during playback)
6. Changed: Updated Cool Edit filter to 3.99.
Monkey's Audio 3.99 Update 1
1. Fixed: MACDll.dll wasn't working on Win9x / ME systems.
2. Changed: MAC.exe updated to 3.99.
Monkey's Audio 3.99
1. Changed: Decoding engine better at handling corrupt streams / loss of internet connection while playing.
2. Changed: Simplified assembly code building for 3rd party developers.
3. NEW: Improved entropy coder for increased compression.
4. Changed: Removed RKAU support. (since it is no longer commonly used)
Monkey's Audio 3.98a1
1. Changed: Now natively using APE tag version 2 tagging. (updated spec for better streaming and international support)
2. Changed: Using smaller frame sizes with Fast, Normal, and High for faster, smoother seeking.
3. NEW: Added built-in MD5 checking, for super secure, super fast file verification.
4. Changed: Using a new and improved file header format.
5. NEW: Added "Insane" mode for when compression is all that matters.
6. NEW: Introduced new GUI.
- full Unicode support
- few or no dependencies
- multi-thread friendly -- can process multiple files at once
- XML based external plugin architecture
Monkey's Audio 3.97 (July 7, 2002)
1. Changed: "Save File List Between Sessions" now on by default in front end.
2. Changed: Replaced usage of "#pragma once" with more non-MS compiler friendly alterternative.
3. NEW: MakeAPL now supports command line APL generation. (pass a .CUE file (no wildcards yet) -- operates in silent mode using existing settings)
4. Changed: Assembly support no longer required for backwards compatibility. (thanks Torgeir Strand Henriksen)
5. Changed: Several non-Windows buildability issues.
6. Changed: Using NASM to compile all assembly code. (aids cross-platform buildability)
7. Changed: Encapsulated the APELink code.
8. Changed: Tags aren't analyzed immediately when opening an http:// or m01p:// stream.
9. Changed: Added more functionality to the APL parser.
10. Changed: Added CreateIAPEDecompressEx2(...) to allow the creation of a ranged decoder.
Monkey's Audio 3.96 (April 7, 2002)
1. Fixed: WAV analysis could hang on invalid wav files.
2. Changed: Monkey's Audio would try to analyze files with file extensions not related to Monkey's Audio.
3. NEW: Added APE_DECOMPRESS_AVERAGE_BITRATE field so APL's can report the bitrate for the region they represent.
4. Changed: Improved overall non-Windows build-ability. (MACLib.lib doesn't require <windows.h> to build)
5. Changed: APL parser no longer requires Windows.
6. Fixed: APE tagging code would fail to save tags for files with existing ID3v1 tags.
7. Fixed: MakeAPL would not run on Win95 / 98.
8. Changed: More non-Windows build-ability issues.
9. Changed: Minor assembly optimizations. (like a 2% performance improvement)
10. Changed: MACLib now builds with gcc under Linux. (no backwards compatibility or assembly support yet)
11. Fixed: Bitstream fix / change that may have accounted for decompression failures in extremely rare cases.
12. Changed: Slight NNFilter optimization. (thanks to Chun-Yu Shei)
13. Changed: Turned off "Explorer" by default for the Monkey's Audio GUI. (doesn't work well under XP... will still leave it in for a while)
14. Changed: Included the WavPack 3.93.
15. Changed: Changed the history reporting method.

/*****************************************************************************************
APEInfo.h
Copyright (C) 2000 by Matthew T. Ashland All Rights Reserved.
Simple method for working with APE files... it encapsulates reading, writing and getting
file information. Just create a CAPEInfo class, call OpenFile(), and use the class methods
to do whatever you need... the destructor will take care of any cleanup
Notes:
-Most all functions return 0 upon success, and some error code (other than 0) on
failure. However, all of the file functions that are wrapped from the Win32 API
return 0 on failure and some other number on success. This applies to ReadFile,
WriteFile, SetFilePointer, etc...
WARNING:
-This class driven system for using Monkey's Audio is still in development, so
I can't make any guarantees that the classes and libraries won't change before
everything gets finalized. Use them at your own risk

/*****************************************************************************************
Monkey's Audio MACLib.h (include for using MACLib.lib in your projects)
Copyright (C) 2000-2003 by Matthew T. Ashland All Rights Reserved.
Overview:
There are two main interfaces... create one (using CreateIAPExxx) and go to town:
IAPECompress - for creating APE files
IAPEDecompress - for decompressing and analyzing APE files
Note(s):
Unless otherwise specified, functions return ERROR_SUCCESS (0) on success and an
error code on failure.
The terminology "Sample" refers to a single sample value, and "Block" refers
to a collection of "Channel" samples. For simplicity, MAC typically uses blocks
everywhere so that channel mis-alignment cannot happen. (i.e. on a CD, a sample is
2 bytes and a block is 4 bytes ([2 bytes per sample] * [2 channels] = 4 bytes))
Questions / Suggestions:
Please direct questions or comments to the Monkey's Audio developers board:

#ifndef APE_MACLIB_H
#define APE_MACLIB_H
/*************************************************************************************************
APE File Format Overview: (pieces in order -- only valid for the latest version APE files)
JUNK - any amount of "junk" before the APE_DESCRIPTOR (so people that put ID3v2 tags on the files aren't hosed)
APE_DESCRIPTOR - defines the sizes (and offsets) of all the pieces, as well as the MD5 checksum
APE_HEADER - describes all of the necessary information about the APE file
SEEK TABLE - the table that represents seek offsets [optional]
HEADER DATA - the pre-audio data from the original file [optional]
APE FRAMES - the actual compressed audio (broken into frames for seekability)
TERMINATING DATA - the post-audio data from the original file [optional]
TAG - describes all the properties of the file [optional]
Notes:
Junk:
This block may not be supported in the future, so don't write any software that adds meta data
before the APE_DESCRIPTOR. Please use the APE Tag for any meta data.
Seek Table:
A 32-bit unsigned integer array of offsets from the header to the frame data. May become "delta"
values someday to better suit huge files.
MD5 Hash:
Since the header is the last part written to an APE file, you must calculate the MD5 checksum out of order.
So, you first calculate from the tail of the seek table to the end of the terminating data.
Then, go back and do from the end of the descriptor to the tail of the seek table.
You may wish to just cache the header data when starting and run it last, so you don't
need to seek back in the I/O.

-the distinction between APE_INFO_XXXX and APE_DECOMPRESS_XXXX is that the first is querying the APE
information engine, and the other is querying the decompressor, and since the decompressor can be
a range of an APE file (for APL), differences will arise. Typically, use the APE_DECOMPRESS_XXXX
fields when querying for info about the length, etc. so APL will work properly.
