//////////////////////////////////////////////////////////////////////////// // **** WAVPACK **** // // Hybrid Lossless Wavefile Compressor // // Copyright (c) 19*** - 2006 Conifer Software. // // All Rights Reserved. // // Distributed under the BSD Software License (see license.txt) // //////////////////////////////////////////////////////////////////////////// This package contains all the source code required to build the WavPack command-line programs and the WavPack library and it has been tested on many platforms. On Windows there are solution and project files for Visual Studio 2005 and additional sourcecode to build the CoolEdit/Audition plugin and the winamp plugin. The CoolEdit/Audition plugin provides a good example for using the library to both read and write WavPack files. To build everything on Linux, type: 1. ./configure [--enable-mmx] 2. make 3. make install (optionally, to install into /usr/local/bin) If you are using the code directly from SVN (rather than a distribution) then you will need to do a ./autogen.sh before the configure step. For processors that support MMX, use the --enable-mmx switch to utilize MMX intrinsics to speed up encoding of stereo 24-bit (and higher) audio. Notes: 1. There are two documentation files contained in the distribution: doc/library_use.txt contains a detailed description of the API provided by WavPack library appropriate for read and writing WavPack files doc/file_format.txt contains a description of the WavPack file format, including details needed for parsing WavPack blocks and interpreting the block header and flags There is also a description of the WavPack algorithms in the forth edition of David Salomon's book "Data Compression: The Complete Reference". The section on WavPack can be found here: www.wavpack.com/WavPack.pdf 2. This code is designed to be easy to port to other platforms. File I/O is done with streams and all file functions (except "fopen") are handled in a wrapper in the "utils.c" module. The code is endian-independent. To maintain compatibility on various platforms, the following conventions are used: A "short" must be 16-bits and an "int" must be 32-bits. The "long" type is not used. The "char" type must be 8-bits, signed or unsigned. 3. For WavPack file decoding, a library interface in "wputils.c" provides all the functionality required for both the winamp plugin and the "wvunpack" command-line program (including the transparent decoding of "correction" files). There is also an alternate entry point that uses reader callbacks for all input, although in this case it is the caller's responsibility to to open the "correction" file. The header file "include/wavpack.h" includes everything needed while hiding all the WavPack internals from the application. 4. For WavPack file creation, the library interface in "wputils.c" provides all the functionality for both the Audition filter and the "wavpack" command-line program. No file I/O is performed by the library when creating WavPack files. Instead, the user supplies a "write_block" function that accepts completed WavPack blocks. It is also possible to append APEv2 tags to WavPack files during creation and edit APEv2 tags on existing files (although there is no support currently for "binary" fields in the tags). 5. The following #define's can be optionally used to eliminate some functionality to create smaller binaries. It is important that they must be specified the same for the compilation of ALL files: NO_UNPACK no unpacking of audio samples from WavPack files (also don't include unpack.c) NO_PACK no creating WavPack files from raw audio data (also don't include pack.c, extra1.c and extra2.c) INFO_ONLY to obtain information from WavPack files, but not audio (also don't include pack.c, extra1.c and extra2.c) NO_SEEKING to not allow seeking to a specific sample index (unpack only) NO_USE_FSTREAMS to not open WavPack files by name using fstreams NO_TAGS to not read specified fields from ID3v1 and APEv2 tags and create APEv2 tags VER4_ONLY to only handle WavPack files from versions 4.0 onward WIN32 required for Win32 platform 6. There are alternate versions of this library available specifically designed for "resource limited" CPUs or hardware encoding and decoding. There is the "tiny decoder" library which works with less than 32k of code and less than 4k of data and has assembly language optimizations for the ARM and Freescale ColdFire CPUs. The "tiny encoder" is also designed for embedded use and handles the pure lossless, lossy, and hybrid lossless modes. Neither of the "tiny" versions use any memory allocation functions nor do they require floating-point arithmetic support. For applications requiring very low latency, there is a special version of the library that supports a variation on the regular WavPack block format to facilitate this. 7.
