libsamplerate 0.1.2

Secret Rabbit Code (aka libsamplerate) is a Sample Rate Converter for audio. One example of where such a thing would be useful is converting audio from the CD sample rate of 44.1kHz to the 48kHz sample rate used by DAT players.
SRC is capable of arbitrary and time varying conversions ; from downsampling by a factor of 256 to upsampling by the same factor. Arbitrary in this case means that the ratio of input and output sample rates can be an irrational number. The conversion ratio can also vary with time for speeding up and slowing down effects.
SRC provides a small set of converters to allow quality to be traded off against computation cost. The current best converter provides a signal-to-noise ratio of 97dB with -3dB passband extending from DC to 96% of the theoretical best bandwidth for a given pair of input and output sample rates.
Since the library has few dependencies beyond that provided by the standard C library, it should compile and work on just about any operating system. It is know to work on Linux, MacOSX, Win32 and Solaris. With some relatively minor hacking it should also be relatively easy to port it to embedded systems and digital signal processors.
In addition, the library comes with a comprehensive test suite which can validate the performance of the library on new platforms.
Enhancements:
- configure.ac Win32/Makefile.mingw.in
- Add preliminary support for compiling on Win32 using MinGW.
- configure.ac
- Bump version to 0.1.2.
- Add --enable-gcc-werror configure option.
- examples/sndfile-resample.c tests/src-evaluate.c
- Use ISO C standard function remove instead of unlink.
- Win32/Makefile.msvc
- Add the top level directory to the include path (for sndfile.h).
