This is libsamplerate, `0.1.9`.
|
||||
|
||||
libsamplerate (also known as Secret Rabbit Code) is a library for performing sample rate conversion of audio data.
|
||||
|
||||
* The [`src/`](https://github.com/libsndfile/libsamplerate/tree/master/src) directory contains the source code for library itself.
|
||||
* The [`docs/`](https://github.com/libsndfile/libsamplerate/tree/master/docs) directory contains the libsamplerate documentation.
|
||||
* The [`examples/`](https://github.com/libsndfile/libsamplerate/tree/master/examples) directory contains examples of how to write code using libsamplerate.
|
||||
* The [`tests/`](https://github.com/libsndfile/libsamplerate/tree/master/tests) directory contains programs which link against libsamplerate and test its functionality.
|
||||
* The [`Win32/`](https://github.com/libsndfile/libsamplerate/tree/master/Win32) directory contains files and documentation to allow libsamplerate to compile under Win32 with the Microsoft Visual C++ compiler.
|
||||

||||

## Build Status
|
||||
|
||||
| Branch | Status |
|
||||
|----------------|-------------------------------------------------------------------------------------------------------------------|
|
||||
| `master` |  |
|
||||
|
||||
Branches [actively built](https://github.com/libsndfile/libsamplerate/actions) by GitHub Actions.
|
||||
|
||||
---
|
||||
|
||||
## Win32
|
||||
|
||||
There are detailed instructions for building libsamplerate on Win32 in the file [`docs/win32.md`](https://github.com/libsndfile/libsamplerate/tree/master/docs/win32.md).
|
||||
|
||||
## macOS
|
||||
|
||||
Building on macOS should be the same as building it on any other Unix platform.
|
||||
|
||||
## Other Platforms
|
||||
|
||||
To compile libsamplerate on platforms which have a Bourne compatible shell, an ANSI C compiler and a make utility should require no more that the following three commands:
|
||||
```bash
|
||||
./configure
|
||||
make
|
||||
make install
|
||||
```
|
||||
|
||||
## CMake
|
||||
|
||||
There is a new [CMake](https://cmake.org/download/)-based build system available:
|
||||
```bash
|
||||
mkdir build
|
||||
cd build
|
||||
cmake ..
|
||||
make
|
||||
```
|
||||
|
||||
* Use `cmake -DCMAKE_BUILD_TYPE=Release ..` to make a release build.
|
||||
* Use `cmake -DBUILD_SHARED_LIBS=ON ..` to build a shared library.

%description
|
||||
libsamplerate is a C library capable of arbitrary and time varying
|
||||
conversions; from downsampling by a factor of 12 to upsampling by the
|
||||
same factor. The conversion ratio can also vary with time for speeding
|
||||
up and slowing down effects.
