     1 This README covers the Ogg Vorbis 'Tremor' integer playback codec
       
     2 source as of date 2002 09 02, version 1.0.0.

     6 The C source in this package will build on any ANSI C compiler and
       
     7 function completely and properly on any platform.  The included build
       
     8 system assumes GNU build system and make tools (m4, automake,
       
     9 autoconf, libtool and gmake).  GCC is not required, although GCC is
       
    10 the most tested compiler.  To build using GNU tools, type in the
       
    11 source directory:
       
    12 
       
    13 ./autogen.sh
       
    14 make
       
    15 
       
    16 Currently, the source implements playback in pure C on all platforms
       
    17 except ARM, where a [currently] small amount of assembly (see
       
    18 asm_arm.h) is used to implement 64 bit math operations and fast LSP
       
    19 computation.  If building on ARM without the benefit of GNU build
       
    20 system tools, be sure that '_ARM_ASSEM_' is #defined by the build
       
    21 system if this assembly is desired, else the resulting library will
       
    22 use whatever 64 bit math builtins the compiler implements.
       
    23 
       
    24 No math library is required by this source.  No floating point
       
    25 operations are used at any point in either setup or decode.  This
       
    26 decoder library will properly decode any past, current or future
       
    27 Vorbis I file or stream.

    31 The build system produces a static and [when supported by the OS]
       
    32 dynamic library named 'libvorbisidec'.  This library exposes an API
       
    33 nearly identical to the BSD reference library's 'libvorbisfile',
       
    34 including all the features familiar to users of vorbisfile.  This API
       
    35 is similar enough that the proper header file to include is named
       
    36 'ivorbisfile.h' [included in the source build directory].  Lower level
       
    37 libvorbis-style headers and structures are in 'ivorbiscodec.h'
       
    38 [included in the source build directory]. A simple example program,
       
    39 ivorbisfile_example.c, can be built with 'make example'.
