This is libsamplerate, 0.1.9
|
||||
|
||||
libsamplerate (also known as Secret Rabbit Code) is a library for
|
||||
perfroming sample rate conversion of audio data.
|
||||
|
||||
The src/ directory contains the source code for library itself.
|
||||
|
||||
The doc/ directory contains the libsamplerate documentation.
|
||||
|
||||
The examples/ directory contains examples of how to write code using
|
||||
libsamplerate.
|
||||
|
||||
The tests/ directory contains programs which link against
|
||||
libsamplerate and test its functionality.
|
||||
|
||||
The Win32/ directory contains files and documentation to allow
|
||||
libsamplerate to compile under Win32 with the Microsoft Visual C++
|
||||
compiler.
|
||||
|
||||
Win32
|
||||
-----
|
||||
There are detailed instructions for building libsamplerate on Win32
|
||||
in the file
|
||||
|
||||
doc/win32.html
|
||||
|
||||
|
||||
MacOSX
|
||||
------
|
||||
Building on MacOSX should be the same as building it on any other
|
||||
Unix.
|
||||
|
||||
|
||||
OTHER PLATFORMS
|
||||
---------------
|
||||
To compile libsamplerate on platforms which have a Bourne Shell compatible
|
||||
shell, an ANSI C compiler and a make utility should require no more that
|
||||
the following three commands :
|
||||
./configure
|
||||
make
|
||||
make install
|
||||
|
||||

** On Intel Pentium processors (especially PIII and probably P4), converting

**

** Fortunately the ISO C99 specifications define the functions lrint, lrintf,

** llrint and llrintf which fix this problem as a side effect.

**
